What is an AMR file?

AMR – AMR voice audio. AMR is the audio format of mobile phone voice calls and old voice memos: tiny files, made for speech, not music. Converting makes a new file: the sound is decoded and written again, so converting from a lossy format never brings back what was lost.

What is a WAV file?

WAV – WAV audio. WAV is uncompressed audio from Microsoft and IBM: every sample is kept, so files are large (about 10 MB a minute) and editing programs love them. Converting makes a new file: the sound is decoded and written again, so converting from a lossy format never brings back what was lost.

Good to know

  • The sound is decoded and written as a WAV file, every sample kept.
  • AMR lost detail when it was made, and WAV cannot bring it back: the file gets bigger but sounds the same as the AMR.
  • Tags such as title and artist are kept where the new format has room for them. Only the first audio track is converted; pictures and video are left out.
