AMR is the format many call recorders, older Android phones and feature phones use for voice recordings. Computers and modern players often cannot open it. Convert AMR to MP3 to listen, share or keep the recording safely.

AMR vs MP3: what changes

AMR (Adaptive Multi-Rate) was designed for mobile phone calls, so it squeezes speech into very small files at telephone quality. MP3 is a general-purpose format that plays everywhere. The MP3 sounds the same as the recording but takes more space, because MP3 is not specialised for narrow-band speech.

When to convert AMR to MP3

Use it for call recordings you need to share, voice memos from an old phone, recordings requested as evidence or for transcription, and any .amr file that will not play on your computer.

Before you convert

AMR recordings are made at telephone quality, usually 8 kHz, so they sound muffled compared with music. Converting cannot add the missing detail. The MP3 will also be larger than the tiny AMR file. Follow the law in your country about recording and sharing calls.

Convert AMR to MP3 on any device

Call recordings on Android are usually in a folder named Call, Recordings or Sounds in internal storage. Open this page on the phone, tap the upload box and choose the file from Files.

Common problems and fixes

My call recording is in .amr and will not open

Many Android call recorders and older phones save AMR, designed for voice over phone networks. MP3 opens in every player and email.

The MP3 still sounds like a phone call

AMR records only the narrow frequency range of a phone call. Converting keeps that range; it cannot add missing detail.

Is the MP3 much bigger?

Yes, AMR is tiny (about 1 MB for ten minutes). The MP3 is larger but plays anywhere.

Frequently asked questions

Does AMR-WB (wideband) work too?

Yes. Both AMR-NB and AMR-WB recordings are supported, including .3ga files from some Samsung phones.

Why does the recording sound like a phone call?

AMR stores only the frequencies needed for speech on a phone line. The MP3 keeps exactly that sound.
