Import a batch
Create a named batch and choose files through Android Files. Each batch holds up to 12 clips. Use mono/stereo audio lasting 0.4–180 seconds, at most 50 MB per input, sampled at 8–192 kHz. PCM16/24/32 and float32 RIFF WAV are supported. Android system decoders can also read supported MP3, M4A/AAC, FLAC and Ogg files. Codec support depends on the device. AIFF, RF64 and multichannel audio are unsupported.
Working copies use 48 kHz float32 WAV. Other rates use a 32-tap, 1024-phase windowed-sinc conversion. Tags, artwork and original codec data are omitted. Keep originals separately. Limits: 12 batches, 12 clips per batch, 20 saved targets and 400 MB of private working WAVs, including unused files until cleanup.
Set, render and inspect
Choose a target from −30 to −8 LUFS and a sample peak ceiling from −6 to −0.5 dBFS. Apply settings explicitly. A measured clip in range can provide the reference target. Existing outputs are eligible only when their target and ceiling exactly match current settings.
The meter uses 48 kHz K weighting, 400 ms blocks with 100 ms steps, an absolute −70 LUFS gate and a relative −10 LU gate. It sums mono/stereo channel energy without dual-mono compensation. Constant gain is shared across stereo channels. Below-gate silence cannot be matched. Sample peak protection can leave a clip below the target; it is not a limiter or compressor.
Listen and save
Listen to actual working source or current rendered result. Playback stops when the app is paused or local work starts. Save a chosen WAV, measurements CSV or settings JSON, or a ZIP of current included WAVs with Measurements.csv, Settings.json and Readme.txt. Measurements are taken from actual written files. Saving does not establish recipient delivery. This bundle cannot restore editable projects.
Local recovery
Failed index writes preserve previously committed data. An unreadable index blocks normal writes. Save the exact unreadable copy before resetting links. Reset keeps working audio until you explicitly clean unused files; it does not reconstruct projects. Retry unused-audio cleanup in Help. Clearing cached exports preserves saved batches and external files. Save original and external copies before deleting a clip, a batch or the app.
