SoundTree Recorder

Audio recorder with topic organization, marks, and page-like waveforms.
New in version 0.10.28
- Added a quick recording button to the Library section so that a recording can be initiated directly from Topic-contexts
- Fixed an issue where volume buttons didn't work during playback over Bluetooth headphones.
- Fixed the Input Source button on the Record tab showing a stale device after it was disconnected (e.g. unplugging a USB microphone)
- The Input Source picker now shows previously selected devices that are no longer connected, greyed out, instead of just dropping them from the list
SoundTree is a personal audio recorder and organizer with an emphasis on bookmarks.

Everything stays on your device - no accounts, no cloud, no tracking, and no network permission at all.

Record high-quality M4A audio with a live scrolling waveform, pause and resume without starting a new file, and save from the notification while your screen is locked. Drop marks during recording or playback to flag moments worth revisiting. Sort recordings into a hierarchical topic tree, nested as deeply as you like. Back up automatically to an external drive or USB device.

Also supports audio-passthrough to earphones for monitoring audio inputs.

  • New in version 0.10.25
    - Improved the Audio Passthrough feature by moving it to a dedicated thread. This should reduce cases where passthrough audio sounds choppy while recording.
    - Reduced startup time on devices with many recordings in the library. This was caused by the orphaned-audio-file safety scan blocking startup until it finished; the scan now runs asynchronously.
    - Fixed a startup bug where the app would sometimes restore to the Listen tab or Library/Details tab with nothing loaded.
