Browser media documentation: pitch preservation and playback speed
A few useful answers
Will my recording be uploaded?
No. Playback uses the file on your device. Only bookmarks and playback settings are remembered in this browser. Reopen the same file to restore them; export a backup to move them.
Can I listen with the screen locked?
Background playback depends on your browser, device and power settings. The browser may suspend playback or segment timers when the tab is hidden or the screen is locked. Keep this tab visible for reliable segment boundaries.
Does changing speed change pitch?
The player requests pitch preservation at every speed. Support and sound quality depend on the browser and file format. If your browser cannot preserve pitch, use normal speed.
