Reverb

Rolling audio recorder for Android
New in version 0.1.1
Preserves recordings, buffer data and legacy settings when upgrading from 0.1.0.
Fixes MediaStore exports and migration, and improves recording interruption history.
Refines inline playback, trim seeking, predictive Back and buffer selection.
Restores the Library Back button and hardens Quick Settings, service handoffs and storage recovery.
Reverb lets you capture audio, keep a rolling history and save the parts you need.

Capture

  • Independent One-shot and Looping buffers

  • Disk-backed audio history that restores across app restarts

  • Configurable retention limits by time or size

  • Hardware-aware audio format, sample rate, source, route and channel options



Save and listen

  • Select a range on the waveform and export it as WAV

  • Listen while fine-tuning your selection

  • Play saved recordings directly in the Library

  • Trim into a new recording while preserving the original

  • Rename, move and delete saved recordings



Privacy
No ads, trackers or accounts. Reverb does not request network permission.

Battery use
Continuous microphone capture consumes power even though Reverb reduces work
when its capture screen is not visible. Battery use varies by device and
recording settings.
