Reverb

Rolling audio recorder for Android

SmallThingz Recorder

Description

Reverb keeps a rolling audio buffer on your Android device so you can save something that has just happened. Audio that you do not save is automatically discarded as the buffer rolls forward. Features

  • Disk-backed rolling buffer that survives app restarts
  • Streamed WAV export without loading the full recording into memory
  • Built-in playback, rename, delete, and move tools
  • Configurable retention time and storage limits
  • Hardware-aware audio format, sample rate, source, route, and channel options
  • No ads, trackers, accounts, or network access
Battery use Continuous microphone capture consumes power even though Reverb reduces work when its capture screen is not visible. Battery impact varies by device and is similar to continuous audio playback.
