About AMR to PCM
Convert AMR to PCM. AMR encodes narrowband speech for GSM calls at 12.2 kbps and below. PCM is raw pulse-code samples with no container or headers. Sample rate and width must be set by hand since headers carry none..
Why convert AMR to PCM?
- Larger files than lossy shares with PCM uncompressed quality.
- Keep quality where supported.
- Private, no upload - runs in your browser.
AMR vs PCM
| Codec | AMR-NB | PCM 16-bit |
|---|---|---|
| Compression | lossy | uncompressed |
| Sample behavior | Quality set by bitrate | Full quality kept |
| Typical use | AMR encodes narrowband speech for GSM calls at 12.2 kbps and below. | PCM is raw pulse-code samples with no container or headers. |
When not to convert AMR to PCM
- Skip PCM for the smallest share: lossless output stays large, so prefer a lossy target when sending AMR files.
- Keep a master copy: repeated exports stack small losses, so archive AMR before batch PCM shares.
Limits
Starting point: AMR - AMR encodes narrowband speech for GSM calls at 12.2 kbps and below. Tuned for voice calls, so music loses detail by design. Sample rate and width must be set by hand since headers carry none. Encode PCM (PCM 16-bit) from AMR at 256k for music or 128k for speech, starting from the master.
