About AMR to LPCM
Convert AMR to LPCM. AMR encodes narrowband speech for GSM calls at 12.2 kbps and below. LPCM is linear PCM as carried on DVD and Blu-ray discs. Disc rips may interleave channels; verify mapping after conversion..
Why convert AMR to LPCM?
- Larger files than lossy shares with LPCM uncompressed quality.
- Keep quality where supported.
- Private, no upload - runs in your browser.
AMR vs LPCM
| 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. | LPCM is linear PCM as carried on DVD and Blu-ray discs. |
When not to convert AMR to LPCM
- Skip LPCM 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 LPCM 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. Disc rips may interleave channels; verify mapping after conversion. Encode LPCM (PCM 16-bit) from AMR at 256k for music or 128k for speech, starting from the master.
