How to convert AMR to WAV
- Add your .AMR file - drop it in the box above or click to browse.
- Convert it to .WAV in a few seconds.
- Download your new .WAV file.
What to expect
- AMR-NB (the standard
.amrfile) records at 8 kHz - telephone bandwidth - so the converted WAV will sound like the original phone call, not a studio recording. - File size grows substantially: a one-minute AMR voice note is roughly 90 KB; the same audio as uncompressed WAV is about 1 MB.
- Some
.amrfiles are actually AMR-Wideband (16 kHz); they will sound noticeably better than a standard AMR-NB file after conversion.
Frequently asked questions
Does converting to WAV improve the audio quality?
No. WAV stores exactly what the AMR decoder outputs. The quality ceiling is fixed by the original AMR recording and cannot be recovered.
Why is the converted WAV file so much larger than the AMR?
WAV stores raw uncompressed audio. A typical AMR voice recording at 12 kbps expands to roughly ten times the original file size as WAV.
Can I convert AMR to WAV on a phone?
On Android, several audio converter apps support AMR natively. On iPhone, AMR is not supported by default - use a desktop tool or the converter above instead.
How do I set a specific sample rate in the output WAV?
With ffmpeg, add the
-ar flag: ffmpeg -i recording.amr -ar 16000 recording.wav.Programs that convert AMR: AMR Player · FormatFactory · Freemake Video Converter · SUPER · Switch Audio File Converter Software
