ADPCM vs MPEG-4 DST
| Codec | ADPCM | MPEG-4 DST |
|---|---|---|
| Compression | lossy | lossless 1-bit |
| Sample behavior | Quality set by bitrate | Full quality kept |
| Typical use | ADPCM predicts samples to quarter voice-band bitrates. | MPEG-4 DST packs 1-bit DSD streams losslessly for archiving. |
When not to convert ADPCM to MPEG-4 DST
- Skip MPEG-4 DST 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 MPEG-4 DST shares.
