Import a source

Tap Import WAV and choose a file in Android Files. Supported input is little-endian RIFF WAV with 2–8 recorded channels, PCM 16/24/32-bit or IEEE float32, and sample rates of 8–192 kHz. Extensible WAV must use all bits in its sample container. RF64, Wave64, compressed WAV and mixed-source stem separation are not supported. Each file may be up to 128 MiB. Keep up to 24 takes and 512 MiB of private source copies.

Choose the tracks

Each lane displays its recorded waveform, sample peak and RMS level. The waveform uses 96 peak buckets across the whole source. Inclusion checkboxes choose which channels will become outputs. Name tracks saves every name together; take names, selections and language survive reopening. Try a sample take explicitly creates synthetic stereo audio. Production starts empty.

Listen and stop

Listen creates a 16-bit mono preview of the first five seconds, or the whole source when shorter. Stop, selecting another take, and leaving the app stop playback. Float peaks can exceed 0 dBFS in the source; previews and outputs saturate at full scale.

Create and save WAVs

Create WAVs writes a separate 24-bit PCM mono WAV per selected channel at the original sample rate and duration. It does not resample, normalize, dither or copy source metadata. Integer PCM keeps its most significant 24 bits; float samples clip to the signed full-scale range and round to 24-bit values. The source checksum is checked before and after extraction. Output names include a channel number and a sanitized track name.

Save ZIP opens Android Files with the mono WAVs and an export manifest. Individual download buttons save one WAV. Share ZIP opens Android’s recipient chooser; delivery depends on the chosen recipient app. Android may remove cached exports. Save copies outside the app. The private export cache is limited to 512 MiB; use Help → Clear cached exports after saving them. Each export gets a separate private directory, so creating a new export does not overwrite an earlier shared result.

Storage and deletion

The imported source is copied into app-private storage. Removing a take removes its private source and names after confirmation; previously created cached and externally saved exports can remain. Clear cached exports is a separate confirmed action and may invalidate old shared cache links. Retry source cleanup handles a previously failed deletion. An unreadable saved library is preserved; Help offers Retry opening library and Save unreadable index. Android automatic cloud backup is disabled. Clearing app data or uninstalling removes private records.
