Make sure audio or video is present on the page — navigate to a page that contains media.\n2. Start playback on the page before opening the extension.\n3. If prompted, click **Allow access** and approve the browser permission dialog.\n4. Open the video or audio on its own dedicated page rather than in an embedded player.\n5. Reload the page and try again.\n6. If the site uses a non-standard or protected player, switch to **Tab audio mode** as a fallback: click {{icon:screenshot_monitor}} or go to Settings {{icon:tune}} → *Tab audio mode*.\n\nIf the problem persists, temporarily disable extensions that may interfere with audio or page execution, such as:\n\n - VPNs with filtering\n - Audio capture or recording extensions\n - YouTube enhancers, equalizers, or volume control extensions\n - Exam or proctoring software\n\nSome environments intentionally restrict access to media and advanced browser features. This is common on:\n\n - School or exam devices\n - Work or enterprise-managed browsers\n - Systems with proctoring or lockdown software\n\n**Pro (side panel):** Navigate to a page with media — the side panel reconnects automatically. If the side panel is unresponsive, click the Transpose extension icon in the toolbar to re-activate the tab, then close and reopen the side panel if needed. \n\n\n<tags>troubleshooting, no playable media, page not supported, connection, tab capture</tags>\n\n---\n\n# Message: \"Activation required\"\n\n<!-- panel:allow-access -->\n<!-- panel:allowaccess -->\n<!-- panel:activationhost -->\n<!-- panel:activationembedded -->\n<!-- panel:disconnected -->\n<!-- panel:reactivation -->\n\n`Classic` `Pro`\n\nThis message appears in two situations:\n\n**New permission needed**\n\nThe message *\"Activate Transpose on this site to continue.\"* means the extension needs explicit permission to connect to audio or video on the current site.\n\nThis can happen because:\n- **Host permission** — the main page domain requires permission.\n- **Embedded player** — an embedded player (e.g. a YouTube video on a third-party site) is on a different domain that also needs permission.\n\n**What to do**\n1. Click **Allow access** in the message.\n2. Approve the browser permission prompt that appears.\n3. The extension will reconnect automatically.\n\nKeep the permission enabled for that site so Transpose reconnects on future visits.\n\n**If it keeps asking**\n- Allow access once for each domain that prompts — the host page and an embedded player may be on different domains.\n- If a VPN, ad blocker, or privacy extension is blocking the permission prompt, disable it temporarily and try again.\n- On managed/work/school devices, browser policies may prevent granting permissions. Use **Tab audio mode** as a fallback: Settings {{icon:tune}} → *Tab audio mode*.\n\n**Reconnecting (permission already granted)**\n\nThe message *\"Activate Transpose from the browser toolbar to continue on this page.\"* means permission is already granted but the connection to the page was interrupted.\n\nThis can happen when:\n- You navigated to a different page while the side panel was open.\n- The page was reloaded.\n- The extension was updated or the content script was unloaded (e.g. tab was discarded by the browser).\n\n**What to do**\n1. Click the Transpose extension icon in the toolbar to re-inject and reconnect on the current page.\n2. If that doesn't work, close and reopen the side panel.\n3. **Popup:** Close the popup and reopen it on the new page.\n4. If Transpose still does not connect, reload the page.\n\nAfter re-activation, Transpose reconnects automatically if media is playing on the page.\n\n\n\n<tags>troubleshooting, activation required, allow access, add permissions, connection, disconnected, reconnect</tags>\n\n---\n\n# Message: \"Start playback\"\n\n<!-- panel:start-playback -->\n<!-- panel:startplayback -->\n\n`Classic` `Pro`\n\nTranspose shows **\"Start playback\"** with the message *\"Start audio or video on this page to activate Transpose.\"* This means media exists on the page but is not yet playing, or a page reload or tab navigation caused the connection to go stale.\n\n**What to do**\n1. Press Play in the site's player to start audio or video.\n2. If Transpose still does not connect after playback starts, reload the page and open the extension again.\n\n<tags>troubleshooting, start playback, connection, no media</tags>\n\n---\n\n# Message: \"Pitch not available\"\n\n<!-- panel:no-pitch-shift -->\n<!-- panel:nopitchshift -->\n<!-- panel:no-compatible-player -->\n<!-- panel:nocompatibleplayer -->\n\n`Classic` `Pro`\n\nThese messages appear when Transpose can detect audio playing on the page but cannot attach its pitch processor directly to the media element:\n- **Pitch not available** — *\"Use tab capture to continue with pitch shifting on this page.\"*\n- **No compatible player detected** — *\"Audio is playing, but no compatible player was detected.\"*\n\nThis typically happens on sites that use protected, non-standard, or offscreen audio routing.\n\n**What to do**\n\nSwitch to **Tab audio mode** as a fallback:\n1. Click the **Use tab capture** button, or go to Settings {{icon:tune}} → *Tab audio mode*.\n2. Approve the browser capture prompt if it appears.\n3. Pitch and speed control will be available for all audio on the tab.\n\nIf other audio/video extensions are installed, try disabling them — they can conflict with Transpose's audio processing.\n\nOn many sites, playback controls (play, loop, markers) still work via the direct connection — only the pitch processing is handled through tab audio.\n\n<tags>troubleshooting, pitch not available, no compatible player detected, tab capture, tab audio, connection</tags>\n\n---\n\n# What is Tab Capture mode?\n\n`Classic` `Pro`\n\nTab Capture {{icon:screenshot_monitor}} processes **all audio** from the browser tab. \n\nUse it when direct access to a video/audio element is blocked. \n\n**When to use it**\n- The extension shows \"No media\" or cannot detect a compatible player.\n- The site uses a non-standard audio setup that blocks direct connection. \n\n**How to start Tab Capture**\n- Use the {{icon:screenshot_monitor}} action when shown in connection/troubleshooting messages, or open Settings {{icon:tune}} → **Tab audio mode**. \n\n**How to exit Tab Capture**\n- Open Settings {{icon:tune}} and turn off the **Tab audio mode** toggle, or close and reopen the extension on the page. \n\n<tags>tab capture, tabcapture, troubleshooting, settings, no media</tags>\n\n---\n\n# Audio quality issues: glitches, stuttering, distortion\n\n`Classic` `Pro`\n\nFree and Pro versions both depend on device performance. \n\nTips:\n- Close other tabs and applications.\n- Disable unnecessary extensions.\n- Check your task manager for background processes (e.g. updates, backups, virus scans) that may affect audio performance.\n- Restart browser or computer.\n- Check sound card sample rate (48kHz recommended).\n- On weaker PCs, glitches can still occur — even with Pro. \n\n**Pro users**:\n- Pro uses an improved algorithm that reduces clicks and noise.\n- Delay is much lower compared to Transpose Classic. \n\n<tags>troubleshooting, audio quality, glitches, jitter, stuttering, distortion, performance, noise</tags>\n\n---\n\n# Why is there a delay between audio and video?\n\n`Classic`\n\nPitch shifting requires buffering the audio (200–400ms). \n\nThis delay between audio and video is normal in Transpose Classic. \n\nActual delay can vary by device performance, browser load, and site/player behavior.\n\nThe Pro version uses a different audio engine with much better latency by default. Pro also has a **Low Latency mode** (Settings {{icon:tune}} → *Audio engine options*) for even lower delay — ideal for instrument-following or call-and-response practice.\n\n<tags>delay, latency, sync, lag, classic, pro, low latency</tags>\n\n---\n\n# Do Pro users have less delay?\n\n`Pro` `Features`\n\nYes. \n\nTranspose Pro uses a **more advanced algorithm** with:\n- Minimal audio delay (much closer sync with video).\n- Fewer clicks and artifacts.\n- More natural sound, especially at extreme pitch or speed changes. \n\n**Low Latency mode**\n\nPro also includes a **Low Latency mode** (Settings {{icon:tune}} → *Audio engine options*) that further minimizes perceived delay at the cost of some audio quality. Useful for instrument-following drills or any situation where immediate response matters more than maximum fidelity.\n\n> Note: Low Latency mode is not available while Formant shifting is active.\n\n<tags>delay, latency, sync, lag, pro version, features, low latency</tags>\n\n---\n\n# Can I use local audio or video files?\n\n`Classic` `Pro`\n\nYes.\n1. Open the extension settings (**More options** icon {{icon:more_vert}} → *Play local file*).\n2. Choose an audio or video file (mp3, wav, mp4, mov, etc.) from your computer.\n3. Play it and adjust pitch/speed/loops.\n\n<tags>local files, mp3, wav, mp4, mov, video, offline, from computer</tags>\n\n---\n\n# Can I save audio to a file?\n\n`Classic` `Pro`\n\nNo. \n\nSaving audio streams (e.g. from YouTube) is not allowed by their Terms of Service. \n\nFor offline editing, use tools like **Audacity** with local files.\n\n<tags>save, export, download, record, audacity, mp3</tags>\n\n---\n\n# Can I use Transpose with Chromecast?\n\n`Classic` `Pro`\n\nYes, but only when you cast your **desktop**. \n\nTranspose works by processing audio in your desktop browser tab before casting; it does not provide native Chromecast app/device integration.\n\n<tags>chromecast, casting, tv</tags>\n\n---\n\n# What is Auto Save?\n\n`Classic` `Pro`\n\nWhen a new video starts and you make a change to the Transpose controls, it is saved in your Recent history automatically. The video settings are recalled automatically if you play the video later again and open Transpose.\n- You can disable Auto Save in Settings. \n\n**Related setting: Remember settings**\n- **Remember settings** keeps your last-used values (pitch, speed, etc.) as the startup defaults for new media, even when Auto Reset is on.\n- Disable it if you prefer starting fresh on every video. \n\n<tags>settings, auto save, default, remember settings</tags>\n\n---\n\n# Auto Save history not saved after closing Chrome\n\n`Classic` `Pro`\n\nIf Auto Save is enabled and your recent history or video settings are missing after closing Chrome, check the following:\n- Use Chrome in a normal profile (not Guest or Incognito). You can see this at the top right next to the address bar.\n- Make sure Chrome is not clearing site data on exit. Check Chrome Settings -> Privacy and security, and any cleanup tools you use.\n- Ensure Chrome Sync is enabled, with extensions and settings included. Check Chrome Settings -> You and Google -> Sync and Google services, then Manage what you sync.\n\n\n<tags>auto save, history, settings, video, sync, chrome, troubleshooting</tags>\n\n---\n\n# What is Auto Reset?\n\n`Classic` `Pro`\n\nWhen a new video starts, Auto Reset resets the controls back to their defaults — so each video starts fresh.\n- Previous settings are saved to history first, if Auto Save is on.\n- You can disable Auto Reset in Settings if you prefer your current settings to carry over to the next video in the same tab. \n\n**Interaction with Remember settings**\n- **Remember settings** and **Auto Reset** work differently: \n - **Auto Reset on** → each new video starts from defaults. \n - **Remember settings on** → each new video starts from your last-used values (pitch, speed, transpose, etc.), even across sessions. \n - Enable one or the other depending on whether you want a clean slate or a consistent personal baseline. \n\n<tags>settings, auto reset, default, remember settings</tags>\n\n---\n\n# How do loops work in Transpose Classic?\n\n`Classic` `Features`\n\nTranspose Classic has a simpler loop system with basic markers.\n\n**Adding markers**\n- Click the **bookmark icon** {{icon:bookmark_border}} to save the current time as a marker.\n- Each marker shows its time and optional label. \n\n**Using markers**\n- Click the **→ jump icon** {{icon:skip_next}} to move playback to that marker.\n- If two markers follow each other in time, you can loop that segment by clicking the **loop icon** {{icon:repeat}} between them. \n\n**Loop toolbar options**\n- **Repeat song** {{icon:laps|material-symbols-outlined}} → loop the entire track.\n- **Count in** {{icon:update}} → wait a few seconds before each loop repeat.\n- **Sort** {{icon:sort}} → reorder markers chronologically.\n- **Add** {{icon:playlist_add}} → create a new marker at the current time. \n\nFree loops are handy for quick practice ranges, but they lack the higher precision, editing, and sequencing options of Pro advanced loops.\n\n<tags>free, features, looping, loops, markers</tags>\n\n<!-- suggest screenshot: Pro markers + clips UI -->\n\n---\n\n# Advanced loops\n\n`Pro` `Features`\n\nIn Transpose Pro, loops are much more precise and flexible than in Transpose Classic. \n\nThey use a higher-accuracy algorithm and frame-based timing for smooth, gapless playback.\n\n<img class=\"faq-img\" src=\"/assets/images/pro-loop-button.png\" alt=\"Pro timeline with markers and loop range selected\" style=\"max-width:420px\" />\n\n**Markers and the timeline**\n- Markers appear as numbered circles (1, 2, 3 …) along the timeline.\n- Click any marker to jump playback to that position.\n- Click anywhere on the timeline bar to jump; when paused you get a short (≈300 ms) preview (*scrub time* configurable in Settings).\n- Click the **+** button to add a new marker at the current playback time.\n- Markers are always sorted by time automatically.\n\n**Selecting a loop range**\n- Click the **Range button** {{icon:arrow_range|material-symbols-outlined}} to enter range-select mode.\n- If there are only **two markers**, they are auto-selected as the loop range and the **loop icon** {{icon:repeat}} is enabled.\n- If there are **more markers**, the marker buttons start blinking — click once to choose the start marker, click again to choose the end marker.\n- The selected range is highlighted on the timeline and on the marker chips below it.\n\n<img class=\"faq-img\" src=\"/assets/images/pro-loop-list-range.png\" alt=\"Selecting a loop range in list view\" style=\"max-width:380px;margin-bottom:0\" />\n<p class=\"faq-caption\">Setting range in marker list view</p>\n\n> **Tip:** Long-press any marker button to enter range-select mode directly.\n\n<img class=\"faq-img\" src=\"/assets/images/pro-loop-toolbar.png\" alt=\"Loop toolbar icons\" style=\"max-width:380px\" />\n\n**Toolbar actions** (left to right)\n- {{icon:arrow_range|material-symbols-outlined}} **Select loop range** — select start/end markers for a loop.\n- {{icon:add}} **Add a marker** — create a marker at the current time.\n- {{icon:content_cut}} **Add to clips** — save the selected range as a clip (see below).\n- {{icon:repeat}} **Loop** — activate or deactivate loop playback.\n- {{icon:laps|material-symbols-outlined}} **Repeat song** — loop the entire track.\n- {{icon:update}} **Count in** — wait a few seconds before each loop repeat.\n- {{icon:edit|material-symbols-outlined}} **Edit** — switch to edit mode to rename or adjust markers.\n- {{icon:grid_view|material-symbols-outlined}} **List view / Blocks view** — switch between chip view and list view.\n\n**Editing markers**\n\nClick the **edit icon** {{icon:edit|material-symbols-outlined}} or the **list toggle** {{icon:grid_view|material-symbols-outlined}} to switch to the marker list view, where you can:\n\n- Rename each marker's label.\n- Edit the exact timestamp directly.\n- Set a marker to the current playback position ({{icon:bookmark_border}}).\n\n**Tip:** Combine advanced loops with **clips** (see [Clips and sequences](#clips-and-sequences)) to build step-by-step practice sequences.\n\n<tags>pro, features, looping, loops, markers, clips, timeline</tags>\n\n---\n\n# Clips and sequences\n\n`Pro` `Features`\n\nIn Transpose Pro, practice fragments are stored as **clips**. \n\nA clip is a saved audio range (loop) with its own name, time range, and effect settings — like a bookmark with memory. Clips are tied to a specific section of one track, while saved songs are whole-track entries you can recall later.\n\n<img class=\"faq-img\" src=\"/assets/images/clips-1.png\" alt=\"Pro UI showing markers, timeline and clips panel\" style=\"max-width:520px\" />\n\n**Creating a clip**\n1. Set markers to define the section you want to practice (see [Advanced loops](#advanced-loops)).\n2. Select a range by choosing a start and end marker.\n3. Click the **scissors icon** {{icon:content_cut}} to save the selected range as a clip.\n\nThe clip is added to the **Clips** panel below the markers. In the screenshot above, two clips were created from a song: *\"Pre\"* (01:42.4 → 01:54.7) and *\"Solo\"* (02:08.6 → 02:32.4).\n\n**Clip controls**\n\nEach clip card shows:\n- **Name** — editable label (e.g. \"Pre\", \"Solo\"). Click to rename.\n- **Time range** — start and end timestamps. Click either to adjust.\n- **On/off toggle** — enable or skip the clip in the sequence without deleting it.\n- **Drag handle** {{icon:drag_indicator}} — reorder clips by dragging.\n\nAt the bottom of each clip:\n- {{icon:play_circle||fill}} **Play** — start playback from this clip; the sequence continues after it.\n- {{icon:looks_one}} **Repeat count** — how many times the clip loops before moving on.\n- {{icon:update}} **Count in** — wait a few seconds before each loop repeat.\n- {{icon:more_vert}} **More** — duplicate or delete the clip.\n\n**Adding parameters to a clip**\n- Click the **+** button inside a clip to attach settings such as speed, transpose, formant, or vocal reducer.\n- Each clip remembers its own parameter values, so you can practice the same fragment at different speeds or keys.\n\n**Building a practice sequence**\n- Chain multiple clips together to form a step-by-step practice flow.\n- For example: play the *Pre* section at normal speed → repeat the *Solo* section at 75% speed → repeat the *Solo* again at full speed.\n- Toggle individual clips on/off to focus on specific parts without rebuilding the sequence.\n- The {{icon:laps|material-symbols-outlined}} **loop icon** next to \"Clips\" repeats the entire clip sequence.\n\n<img class=\"faq-img\" src=\"/assets/images/clips-2.png\" alt=\"Repeating a clip at increasing speed\" style=\"max-width:520px;margin-bottom:0\" />\n<p class=\"faq-caption\">Repeating solo at increasing speed</p>\n\nClips let you practice methodically — gradually increasing speed, changing pitch, or isolating sections — without resetting settings manually each time.\n\n<tags>pro, features, clips, sequences, looping, fragments</tags>\n\n---\n\n# What is Varispeed?\n\n`Pro` `Features`\n\nVarispeed **links pitch and speed** together, like a tape deck or turntable — speeding up also raises pitch, slowing down lowers it.\n- Toggle Varispeed in the Speed/Pitch panel to enable the linked behavior.\n- Useful when you want a natural, analog-style pitch-speed relationship rather than independent control. \n\n**Range and quality**\n\nVarispeed only allows a small pitch range (around −2 to +2 semitones). This is by design: within that range, no time-stretch processing is needed, which means the audio stays at its **highest possible quality** with no stretching artifacts. It is the best choice when you only need a slight pitch correction or fine-tuning.\n\n> Pro: Varispeed is available in Pro Trial and Pro Active.\n\n<tags>varispeed, pitch, speed, features, linked, pro, quality</tags>\n\n---\n\n# What is Extended Range?\n\n`Classic` `Pro`\n\nBy default, Transpose shifts pitch by up to **±12 semitones** (one octave up or down).\n\nEnable **Extended Range** in Settings {{icon:tune}} to expand this to **±36 semitones** — three full octaves in either direction.\n- Useful for extreme key shifts, analysis, or specialized practice needs.\n- Available for all users (Free and Pro).\n- In Varispeed mode, the range remains constrained to the tighter linked pitch-speed limits regardless of this setting. \n\n<tags>extended range, transpose, semitones, settings, features</tags>\n\n---\n\n# What is Reference Tuning?\n\n`Pro` `Features`\n\nReference Tuning lets you match Transpose to recordings or instruments that use a **non-standard pitch standard**.\n\nThe default is **A = 440 Hz** (modern international standard). Some recordings, orchestras, or instruments use a different tuning — for example Baroque ensembles often use **A = 415 Hz**, and some recordings use **432 Hz** or **443 Hz**. If you practice along with such material, everything will feel slightly off even when the transposition looks correct.\n\n**How it works**\n\nReference Tuning uses two independent values:\n- **Track tuning** — the pitch standard of the recording you are playing along with.\n- **Instrument tuning** — the pitch standard of your instrument or ensemble. \n\nTranspose calculates the difference and applies it automatically so your pitch adjustments stay in tune with both.\n\n**Practical workflow**\n1.

Set **Instrument** to your instrument's tuning frequency.\n4. Transpose and Pitch values now reflect the corrected difference.\n\n**Built-in presets**\n\nBoth Track and Instrument have quick-select presets:\n\n| Preset | Frequency |\n|---|---|\n| French Baroque | 392 Hz |\n| Baroque | 415 Hz |\n| Classical | 430 Hz |\n| Earth frequency | 432 Hz |\n| Modern | 440 Hz |\n| — | 442 Hz |\n| — | 443 Hz |\n| — | 445 Hz |\n| Chorton | 465 Hz |\n\n> Pro: Reference Tuning is available in Pro Trial and Pro Active.\n\n<tags>pro, features, reference tuning, tuning, 432hz, 440hz, baroque, pitch, settings</tags>\n\n---\n\n# What is Formant control?\n\n`Pro` `Features`\n\nFormant control changes the **timbre** (voice color) without affecting pitch.\n- Useful for adapting male ↔ female voice range.\n- Can make instruments sound darker or brighter. \n\n<tags>pro, features, formant, timbre, voice, sound quality</tags>\n\n---\n\n# Using the Vocal Reducer\n\n`Pro` `Features`\n\nThe Vocal Reducer lowers vocals in stereo music tracks so you can practice along more easily. Use it as a voice reducer on YouTube or any other site Transpose supports.\n\nIt intelligently targets center-panned vocals across multiple frequency ranges while preserving the instruments around them, more precise than basic vocal removal tools.\n\nIt works best on commercially mixed stereo tracks where vocals are centered. It will not fully isolate or remove vocals; it is designed as a practice and karaoke tool, not a studio separator. Results vary depending on the mix.\n\n<img class=\"faq-img\" src=\"/assets/images/vocal-reducer.png\" alt=\"Vocal Reducer controls\" />\n\n**Controls:**\n\n- **Vocal Reducer (Amount)**\n\n The main dry/wet control. Drag it up to hear more of the reduced signal.\n\n - **0%** — original audio, no processing.\n - **100%** — fully processed signal only.\n - Start here and increase until vocals are sufficiently reduced.\n\n- **Intensity**\n\n Controls how aggressively the reducer suppresses detected vocal content.\n\n - Low values give a subtle, natural-sounding reduction — good for light vocal lowering while keeping the mix intact.\n - High values apply deeper suppression in the vocal bands, which can remove more of the vocal but may introduce slight artifacts on some tracks.\n - Works together with Amount: Amount controls how much of the processed signal you hear, while Intensity controls how hard the processing works.\n\n- **Focus**\n\n Controls how narrowly the reducer targets vocal frequencies.\n\n - **Wide** (left) — broader reduction across a wider frequency range. Catches more of the vocal but may slightly affect nearby instruments like piano or guitar.\n - **Narrow** (right) — surgical, precise cuts focused tightly on the detected vocal content. Better for preserving instruments, but may miss vocals that move around in frequency.\n - For most pop/rock tracks, a moderate setting works well. Use narrow for tracks with busy arrangements.\n\n- **Range (Low Hz / High Hz)**\n\n A dual-handle slider that defines which frequencies the reducer is active on (20 Hz – 20 kHz, logarithmic scale).\n\n - **Low Hz** (default 120 Hz) — frequencies below this pass through untouched. Keeps bass and kick drum intact.\n - **High Hz** (default 6000 Hz) — frequencies above this pass through untouched. Preserves cymbals, hi-hats, and high-frequency shimmer.\n - Narrowing the range focuses the reduction on the vocal band and reduces side effects on instruments outside that range.\n\n- **Stereo Bias**\n\n Shifts the center detection point left or right.\n\n - Default is center (0).\n - If the vocal in a particular track is panned slightly off-center, adjust this to better target it.\n - **L** = shift detection toward the left channel, **R** = toward the right.\n\n**Tips:**\n- Start with the **Amount** slider and increase until vocals are noticeably reduced. Then fine-tune with the other controls.\n- If instruments are being affected, try narrowing the **Focus** or tightening the **Range**.\n- Works best on stereo tracks. Mono audio is passed through unprocessed.\n- For backing-track practice, combine the Vocal Reducer with pitch shift and speed control.\n\n<tags>pro, features, vocal reducer, karaoke, remove vocals, practice, voice reducer</tags>\n\n---\n\n# Shaping tone with the Equalizer\n\n`Pro` `Features`\n\nThe Equalizer (EQ) lets you shape the tone of the audio by boosting or cutting specific frequency ranges. It is useful for making instruments stand out, reducing muddiness, or adjusting the overall sound to your preference while practicing.\n\nThe EQ has **6 bands**, each represented as a colored dot on a visual frequency curve. You can drag the dots up or down to boost or cut, and left or right to change the target frequency.\n\n<img class=\"faq-img\" src=\"/assets/images/equalizer.png\" alt=\"Equalizer controls\" />\n\n**Bands and their default roles:**\n\n| Band | Default type | Default frequency | Typical use |\n|------|-------------|-------------------|-------------|\n| 1 | High Pass | 30 Hz | Cuts rumble and sub-bass below a cutoff point |\n| 2 | Low Shelf | 120 Hz | Boosts or cuts the bass region as a whole |\n| 3 | Peaking | 350 Hz | Targets the low-mid range (warmth, muddiness) |\n| 4 | Peaking | 1200 Hz | Targets the mid range (vocals, guitar body) |\n| 5 | Peaking | 3500 Hz | Targets the upper-mid/presence range (clarity, bite) |\n| 6 | High Shelf | 9000 Hz | Boosts or cuts the treble region as a whole |\n\n**How to use it:**\n\n- **Toggle on/off** — use the switch in the header to enable or disable the entire EQ without losing your settings.\n- **Drag dots** — on the visual curve, drag any band dot up/down to change gain (±12 dB) or left/right to shift its frequency.\n- **Select a band** — click a band in the strip below the curve to see its details and adjust the filter type and Q.\n- **Filter type** — click the type label (e.g. \"Peak\", \"Lo Shelf\") to change it. Available types: High Pass, Low Pass, Peaking, Low Shelf, High Shelf, and Notch.\n- **Q (quality)** — controls how wide or narrow the filter's effect is. A low Q affects a broad range; a high Q focuses on a narrow band. Use the +/− buttons to adjust.\n- **Presets** — click the menu {{icon:more_vert}} to choose from built-in presets.\n- **Reset** — use the refresh button to return all bands to flat (0 dB).\n\n**Built-in presets:**\n\n- **Flat** — all bands at 0 dB (reset)\n- **Backing Track Scoop** — reduces mids to push vocals back; good for play-along\n- **Bass Cut / Bass Boost** — reduce or emphasize low frequencies\n- **Mid Scoop** — dip the midrange for a more scooped, modern sound\n- **Treble Cut** — tame harsh or bright recordings\n- **Loudness** — classic loudness curve: boosted bass and treble\n- **Warmth / Brightness** — shift the tonal balance warmer or brighter\n- **Presence Boost** — bring out vocal and instrument clarity\n- **Speech Clarity** — optimize for spoken content or vocal lessons\n- **De-Mud** — reduce the muddy 200–800 Hz range\n- **Harshness Cut** — soften the 2–5 kHz region that can sound fatiguing\n\n**Tips:**\n- Start with a preset that sounds close to what you want, then fine-tune individual bands.\n- Small adjustments (2–4 dB) usually sound more natural than extreme boosts or cuts.\n- Combine the EQ with the Vocal Reducer for more control when practicing with backing tracks.\n\n\n<tags>pro, features, equalizer, eq, tone, frequency, bass, treble, presets</tags>\n\n---\n\n# Do my settings sync between devices?\n\n`Pro` `Features`\n\nYes.\n- Sign in with your Google account.\n- Your **saved songs, playlists, clips, sequences, and history** sync across desktop Chrome where you are signed in with the same Google account.\n- No manual export or import needed. \n\n> Pro: Cloud sync is a Pro feature.
