About AMR and WAV Formats

What is AMR?

AMR is a speech codec standardised by 3GPP in 1999 for mobile phone calls. Narrowband AMR samples at 8 kHz and uses 4.75-12.2 kbps, so files are tiny but limited to telephone-quality voice.

Commonly used for:

  • Phone call recordings
  • Voice notes on older and Android phones
  • Voicemail systems

What is WAV?

WAV was introduced by Microsoft and IBM in 1991 and stores audio as uncompressed PCM samples. CD-quality stereo WAV (16-bit, 44.1 kHz) uses about 10 MB per minute, and every audio editor, DAW and media player can open it.

  • Recording, editing and mixing in any DAW
  • Mastering and archiving at full quality
  • Broadcast, sampling and sound-design work
  • Maximum compatibility with hardware and software

Why convert AMR to WAV?

Few desktop players and transcription tools read AMR; WAV makes voice recordings playable and editable anywhere.

AMR keeps only speech frequencies, so a converted WAV will sound like a phone call. Converting cannot restore missing detail.

Frequently Asked Questions

No further quality is lost: WAV stores the decoded AMR audio without compression. Detail that AMR discarded when it was created cannot be restored, so the WAV will sound the same as the AMR, not better.

AMR is a lossy compressed format, typically 1-2.5 MB per minute. WAV is uncompressed (about 10 MB per minute at CD quality), so the WAV will usually be 5-10x larger.
