Audifold: Channel Inspection

Audifold helps you inspect the channels inside an audio file before you hand it off. Import a supported audio file from Files and see each channel's sample peak, RMS level, near-silent sample share, first signal time, and near-full-scale sample count. A 32-window signal map helps reveal a quiet channel or a late entrance. Keep a local library of audits, add a recipient note, compare two files side by side, then share a clear PDF inspection sheet or editable CSV. Files and reports stay on your device unless you choose to share them. Audifold measures sample levels and timing. It does not calculate LUFS, true peak, clipping, phase, or acoustic quality. Supports decodable audio files with 1–8 channels up to one hour and 512 MB; format support depends on iOS decoding. No account, subscription, ads, analytics, tracking, cloud sync, or developer-server upload.
