| Sample behavior | Quality set by bitrate | Full quality kept |
| Typical use | ADPCM predicts samples to quarter voice-band bitrates. | AIFF is Apple's IFF-based counterpart to WAV with PCM audio. |
When not to convert ADPCM to AIFF
- Skip AIFF for the smallest share: lossless output stays large, so prefer a lossy target when sending ADPCM files.
- Keep a master copy: repeated exports stack small losses, so archive ADPCM before batch AIFF shares.
