AMR to WAV Converter

How it works

1. Choose your AMR file, or drop it on the page. You can add several files at once.
2. Pick the sample rate and bit depth, or keep the source values to avoid any change.
3. Click Convert. Processing happens on your device and shows progress; you can cancel at any time.
4. Preview the result and download the WAV file. With several files, download them all as one ZIP.

About AMR to WAV conversion

AMR (Adaptive Multi-Rate speech codec) suits speech on very small files, and reading old phone recordings. WAV (Waveform Audio File Format, RIFF container) suits editing, mastering, sampling and handing audio between programs without quality loss.

AMR is lossy, and no converter can restore detail that was already discarded. The WAV file will sound the same as the AMR source and will be larger; the point of the conversion is compatibility with software or hardware that needs WAV.

For a 4-minute track, a typical AMR file is about 0.4 MB and a typical WAV file is about 42 MB. Your own result depends on the bitrate and the audio itself.

AMR vs WAV

WAV support: Opens in every audio editor and operating system. Browsers and phones play it, though not every player shows tags.

AMR support: Many phone voice recorders, call recorders and MMS messages use it, but desktop players often do not.

Quality and compatibility notes

• WAV: Large files: about 10 MB per minute at CD quality. The classic format stops at 4 GB, which RF64 extends.
• AMR: Designed for speech only: music sounds thin and narrow. Narrowband AMR is 8 kHz mono.
• Tags: WAV stores limited: RIFF INFO chunks, and BWF or iXML metadata in broadcast files.
