About ADPCM to DTS-HD
Convert ADPCM to DTS-HD. ADPCM predicts samples to quarter voice-band bitrates. DTS-HD adds lossless extensions over the DTS core track. Extension layers may not decode everywhere; verify channel count..
Why convert ADPCM to DTS-HD?
- Larger files than lossy shares with DTS-HD lossless quality.
- Keep quality where supported.
- Private, no upload - runs in your browser.
ADPCM vs DTS-HD
| Codec | ADPCM | DTS |
|---|---|---|
| Compression | lossy | lossless |
| Sample behavior | Quality set by bitrate | Full quality kept |
| Typical use | ADPCM predicts samples to quarter voice-band bitrates. | DTS-HD adds lossless extensions over the DTS core track. |
When not to convert ADPCM to DTS-HD
- Skip DTS-HD 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 DTS-HD shares.
