This is common on:\n\n - School or exam devices\n - Work or enterprise-managed browsers\n - Systems with proctoring or lockdown software\n\nNote that some sites do not allow connection to their media. As a fallback you can use Tab capture mode {{icon:screenshot_monitor}}.\n\nIf none of the above helps, reinstall the extension and try again.\n\n<tags>troubleshooting, no media, no sound, connection error, not working, tab capture</tags>\n\n<!-- suggest screenshot: settings panel with Tab Capture toggle -->\n\n---\n\n# Spotify (Web Player) not working\n\n`Free` `Pro`\n\nIf Spotify is playing via **Spotify Connect** (e.g. \"Playing on iMac\"), the audio is not inside the browser tab, so Transpose cannot connect.\n\nTry this:\n- If prompted, **allow site permissions** for Spotify.\n- Refresh the page, then open Transpose.\n- In Spotify, switch playback to **This Web browser**.\n- Start the track first (via Spotify or the Transpose play button).\n- Open Transpose.\n- **Pro (side panel):** if controls do not reconnect, click the Transpose extension icon in the toolbar to re-activate the tab.\n\nAlso make sure you only have **one Spotify tab** playing. \n\n<tags>spotify, connect, web player, no media, troubleshooting</tags>\n\n---\n\n# What does \"No media\" or \"Page not supported\" mean?\n\n<!-- panel:no-media -->\n<!-- panel:no-media-blocked -->\n\n`Free` `Pro`\n\nThese panels appear when Transpose cannot find controllable media on the current page:\n- **No playable media** — the page has no audio or video that Transpose can attach to.\n- **Page not supported** — the domain or page type is not supported by the extension.\n\n**What to do**\n- Start playback on the page before opening the extension.\n- If prompted, click **Allow access** and approve the browser permission dialog.\n- Open the video or audio on its own dedicated page rather than in an embedded player.\n- Reload the page and try again.\n- 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\n**Pro (side panel):** Navigate to a page with media — the side panel reconnects automatically. If the 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 media, page not supported, connection, tab capture</tags>\n\n---\n\n# Why does Transpose ask me to \"Allow access\"?\n\n<!-- panel:allow-access -->\n\n`Free` `Pro`\n\nThis panel appears when the extension needs explicit permission to connect to audio or video on the current site. This 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- **Re-activation** — you navigated away or the page was reloaded, and the extension needs permission again.\n\n**What to do**\n1. Click **Allow access** in the panel.\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**Pro (side panel):** If the panel appears after navigating away, clicking the Transpose extension icon in the toolbar re-activates the tab and reconnects — without reopening the side panel. Or close and reopen the side panel.\n\n\n<tags>troubleshooting, activation required, allow access, add permissions, connection</tags>\n\n---\n\n# What does \"Start playback\" mean?\n\n<!-- panel:start-playback -->\n\n`Free` `Pro`\n\nThis panel appears when media exists on the page but is not yet playing, or after 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# What does \"Disconnected\" mean?\n\n<!-- panel:disconnected -->\n\n`Free` `Pro`\n\nThis panel appears when the extension was connected but lost its connection to the page. This 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\nUnlike the \"Allow access\" panel, permission is already granted — the issue is that the content-script connection was interrupted.\n\n**What to do**\n- **Side panel:** Click the Transpose extension icon in the toolbar to re-inject and reconnect on the current page. If that doesn't work, close and reopen the side panel.\n- **Popup:** Close the popup and reopen it on the new page.\n- 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<tags>troubleshooting, disconnected, connection lost, reconnect, navigated away</tags>\n\n---\n\n# What does \"Pitch not available\" or \"No compatible player\" mean?\n\n<!-- panel:no-pitch-shift -->\n<!-- panel:no-compatible-player -->\n\n`Free` `Pro`\n\nThese panels appear when Transpose can detect audio playing on the page but cannot attach its pitch processor directly to the media element. This 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 {{icon:screenshot_monitor}} icon in the panel, 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\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, tab capture, tab audio, connection</tags>\n\n---\n\n# What is Tab Capture mode?\n\n`Free` `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 panel action ({{icon:screenshot_monitor}}) when shown in connection/troubleshooting panels, 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`Free` `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\n**Pro users**:\n- Pro uses an improved algorithm that reduces clicks and noise.\n- Delay is much lower compared to the Free version.\n- On weak PCs, glitches can still occur. \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`Free`\n\nPitch shifting requires buffering the audio (200–400ms). \n\nThis delay between audio and video is normal in the Free version. \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, free version, 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 files?\n\n`Free` `Pro`\n\nYes.\n1. Open the extension settings (**More options** icon {{icon:more_vert}} → *Play local file*).\n2. Choose an audio file (mp3, wav, etc.) from your computer.\n3. Play it and adjust pitch/speed/loops.\n\n<tags>local files, mp3, wav, offline, from computer</tags>\n\n---\n\n# Can I save audio to a file?\n\n`Free` `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`Free` `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`Free` `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`Free` `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`Free` `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 advanced loops work?\n\n`Pro` `Features`\n\nIn Transpose Pro, loops are much more precise and flexible than in the Free version. \n\nThey use a higher-accuracy algorithm and frame-based timing for smooth, gapless playback.\n\n**Creating an advanced loop**\n- Click the **Range button** {{icon:arrow_range|material-symbols-outlined}}.\n- If there are only **two markers**, they are auto-selected as the loop range and the **repeat icon** {{icon:repeat}} is enabled.\n- If there are **more markers**, all marker buttons and timeline heads (1, 2, 3 …) start blinking: \n - Click once to choose the start marker. \n - Click again to choose the end marker. \n\n > Long press a marker button to get in to range select mode directly\n\n**Loop playback options**\n- **Repeat icon** {{icon:repeat}} → toggle the current loop on/off.\n- **Laps icon** {{icon:laps|material-symbols-outlined}} → repeat the entire song.\n- **Wait-in count** {{icon:update}} → insert 1–4 metrical counts before each repeat, based on the tempo setting. \n\n**Marker interactions**\n- **Click a marker** → jump playback to that time.\n- **Long-press a marker** → enter *select range mode*.\n- **Markers button** or **Shift + click** → enter *edit markers mode* {{icon:edit}}, where you can: \n - Rename the label. \n - Adjust the exact time (input). \n - Sync the marker to the current playback position ({{icon:pin_drop}}). \n\n**Timeline**\n- Markers are shown as rounded numbered labels (1, 2, 3 …) in chronological order.\n- Click a circle to jump to that time.\n- Click anywhere on the timeline bar to jump; when paused you get a short (≈300 ms) preview (*scrub time* configurable in Settings).\n- Markers are always sorted by time.\n- Click the **+ button** {{icon:playlist_add}} at the end of the marker list to create a new marker at the current time. \n\n**Tip:** Combine advanced loops with **clips** (see [What are clips and how do I use them?](#what-are-clips-and-how-do-i-use-them)) to build step-by-step practice sequences.\n\n<tags>pro, features, looping, loops, markers, clips, timeline</tags>\n\n<!-- suggest screenshot: Pro timeline with markers blinking and loop range active -->\n\n---\n\n# How do loops work in the Free version?\n\n`Free` `Features`\n\nThe Free version 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 **repeat icon** {{icon:repeat}} between them. \n\n**Loop toolbar options**\n- **Repeat song** {{icon:laps|material-symbols-outlined}} → loop the entire track.\n- **Wait-in count** {{icon:update}} → add a short count-in before repeating.\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# 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`Free` `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. Enable **Reference Tuning** in Settings {{icon:tune}} → *Audio engine options*.\n2. In the Pitch panel, set **Track** to the recording's tuning frequency.\n3. 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 are clips and how do I use them?\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 playback and effect settings. \n\nClips are tied to a specific time range in one track, while saved songs are whole-track entries you can recall later.\n\n**Creating a clip**\n1.

Results depend on how the track is mixed.\n\n**Main controls:**\n- **Vocal reducer (Depth)** \n\n Master dry/wet control. \n\n - At **0%** the original signal passes through. \n - At **100%** you only hear the fully processed signal. \n - Default 80% = strong but blended effect.\n- **Vocal Cut (vocalCut)** \n\n Crossfades between two reduction techniques: \n\n - **0%** → multi-band notch filters (precise, cleaner). \n - **100%** → phase cancellation (L–R subtraction, more aggressive, may add artifacts).\n- **Center Focus (centerFocus)** \n\n Shifts the stereo focus of the reduction. \n\n - Useful if vocals are not perfectly centered. \n - Move slightly left or right to better target vocals before Mid-Side processing.\n- **Precision (Q)** \n\n Controls the filter sharpness: \n\n - High Q = very narrow, surgical cuts. \n - Low Q = broader cuts, better for variable vocals but may affect nearby instruments.\n- **Low Cut / High Cut** \n\n Pre-filters to clean the signal before reduction: \n\n - **Low Cut**: removes rumble below e.g. 100 Hz. \n - **High Cut**: removes hiss/\"air\" above e.g. 8000 Hz, helps reduce artifacts from cymbals/hi-hats. \n\n**Tips:**\n- Start with - **Vocal reducer (Depth)** first, then fine-tune the other controls.\n- Works best on stereo mixes where vocals are centered.\n- May not fully remove vocals; it is designed for practice and karaoke use, not for studio-quality separation. \n\n<tags>pro, features, vocal reducer, karaoke, mid-side, remove vocals</tags>\n\n<!-- suggest screenshot: Pro settings panel with Vocal Reducer controls -->\n\n---\n\n# How do I save songs?\n\n`Pro` `Features`\n\nSaved songs is the current workflow name.\n\nIf you previously used the word \"presets,\" this now maps to saved songs in the current UI.\n\nUse the Save flow in side panel History (Recent/Saved) to store songs in lists with their settings.\n\nFor step-by-step instructions, see [How do I save songs to a playlist?](#how-do-i-save-songs-to-a-playlist).\n\n<tags>pro, features, songs, playlists, settings, save, sync</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.
