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. <b>Features</b> <ul> <li>Disk-backed rolling buffer that survives app restarts</li> <li>Streamed WAV export without loading the full recording into memory</li> <li>Built-in playback, rename, delete, and move tools</li> <li>Configurable retention time and storage limits</li> <li>Hardware-aware audio format, sample rate, source, route, and channel options</li> <li>No ads, trackers, accounts, or network access</li> </ul> <b>Battery use</b> 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.
