Reverb

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.
