Should you convert AMR to WAV?

Only when software insists on WAV. It stores the decoded AMR perfectly, but the detail the AMR discarded is already gone, so the WAV is bigger without sounding better.

WAV also plays in more places: every computer, audio editor and DAW, and most phones.

AMR is narrow-band speech audio from phones and call recorders; WAV is uncompressed, studio-quality audio. Use WAV while editing and for systems that demand it, such as phone systems, samplers and some broadcast tools.

How to convert AMR to WAV

  1. 01

    Add your AMR

    Drop your AMR file onto the box, or click to choose it. It is read from your disk and stays there.

  2. 02

    Check the settings

    The output is already set to WAV. Change the bitrate if you want to; the defaults suit most files.

  3. 03

    Save the WAV

    Press convert and save the WAV. Several files come back together as a ZIP.

What changes when AMR becomes WAV

Bigger, not better

WAV can’t restore what AMR compression removed. It does make editing easier and stops further loss, which is why editors and some broadcast systems ask for it.

Phone-quality sources stay phone quality

AMR recordings are usually sampled at 8 kHz for speech. Converting to WAV makes them play anywhere, but can’t add clarity that was never recorded.

A one-time engine download

AMR is decoded by FFmpeg compiled to WebAssembly, a 31 MB download the first time. After that it is cached, and the conversion never leaves your device.

Expect a much larger file

WAV is far bigger for the same content. Choose it because something needs WAV, not to send or store the file. AMR: About 90 KB a minute. WAV: About 10 MB a minute at CD quality.

This page is put together from our notes on each format, choosing only what is true of AMR and WAV, so every pairing states the same facts the same way. How these pages are made.

Why it doesn’t upload

Recordings are often private: interviews, voice notes, unreleased music. Your browser can decode and encode audio itself, so there is no reason to send it anywhere.

How to check for yourself

Worth knowing

  • About the AMR. AMR is sampled at 8 kHz, so converting it to a high-quality format won’t add any clarity; it will still sound like a phone call.
  • About the WAV. A WAV made from an MP3 is ten times bigger but sounds exactly like the MP3; the lost detail doesn’t come back.
  • MP3, WAV, M4A, OGG, Opus and FLAC are converted by your browser directly. WMA, AMR, APE, AC3 and the other specialist formats use the FFmpeg engine, a one-time 31 MB download.

Questions

Does converting AMR to WAV lose quality?

No quality is lost converting to WAV, though it can’t restore what the AMR already discarded.

Will a WAV play in my car or on my phone?

WAV opens everywhere: every computer, audio editor and DAW, and most phones.
