What is AMR?

AMR (Adaptive Multi-Rate) is an audio format optimized for speech. Developed for mobile phone networks, AMR efficiently compresses voice at very low bitrates-as low as 4.75 kbps while remaining intelligible.

Many Android phones save voice recordings in AMR format. The format is also used in MMS messages and VoIP applications. While excellent for speech, AMR is not suitable for music.

Why Convert AMR Files?

AMR files often need conversion because:

  • Limited playback support - Many media players cannot open AMR
  • Quality concerns - AMR is heavily compressed for speech only
  • Editing needs - Audio editors may not support AMR
  • Archival purposes - MP3 or WAV are better for long-term storage

Convert AMR to Other Formats

AMR to MP3

The most common conversion. MP3 plays everywhere and preserves voice recordings in a universally compatible format.

AMR to WAV

Uncompressed audio for editing. WAV files can be imported into any audio editor for processing or transcription.

AMR to M4A

Convert for Apple devices. M4A (AAC) works seamlessly with iPhone, iPad, and iTunes.

AMR to OGG

Open-source alternative for Linux and applications using royalty-free formats.

Convert Other Formats to AMR

Create AMR files for mobile compatibility:

MP3 to AMR

Convert audio for legacy mobile devices or MMS messages. Note that AMR is speech-optimized and will degrade music quality significantly.

WAV to AMR

Compress recordings for minimum file size. Useful when bandwidth or storage is extremely limited.

AMR Technical Specifications

  • Full name: Adaptive Multi-Rate Audio Codec
  • Developer: 3GPP (3rd Generation Partnership Project)
  • File extension: .amr
  • Compression: Lossy (speech-optimized)
  • Bitrate range: 4.75 kbps to 12.2 kbps
  • Sample rate: 8 kHz
  • Channels: Mono only

AMR Compatibility

Devices That Create AMR

  • Many Android voice recorder apps
  • Feature phones
  • Some VoIP applications

Playing AMR Files

AMR has limited native support. VLC media player handles AMR, but many standard players do not. Converting to MP3 ensures playback everywhere.

How to Convert AMR Files

  1. Upload your AMR file - Select your voice recording
  2. Choose your output format - MP3, WAV, M4A, and more
  3. Download converted file - Play your recording anywhere

Works on Any Device

Convert AMR files in your browser:

  • Windows, Mac, Linux, Chromebook
  • Chrome, Firefox, Safari, Edge
  • iPhone, iPad, Android

Pro Tip

If you regularly receive AMR voice recordings, batch convert them to MP3 immediately. This ensures you can always play them and creates a backup in a more stable format.

Common Mistake

Using AMR for music or high-quality audio. AMR is speech-only and will severely degrade any audio that is not voice. Always use appropriate formats for the content type.

Best For

Converting voice memos and recordings from Android phones. Essential for playing mobile voice recordings on computers and other devices.

Not Recommended

Do not use AMR for music, podcasts with music, or any audio requiring quality beyond basic speech intelligibility.

Frequently Asked Questions

AMR (Adaptive Multi-Rate) is an audio format optimized for speech recording on mobile phones. Many Android devices save voice memos in AMR format.

Many media players do not support AMR. VLC can play AMR files, but for universal playback, convert to MP3 which works on all devices and players.

AMR is optimized for speech at very low bitrates (4.75-12.2 kbps). Quality is acceptable for voice but poor for music. It prioritizes intelligibility over fidelity.

AMR to MP3 conversion preserves all information in the AMR file, but AMR is already highly compressed. The MP3 will sound similar to the original AMR-voice-quality audio.

AMR uses extreme compression designed for mobile networks with limited bandwidth. A minute of audio can be under 100KB, compared to 1MB+ for MP3.

No. AMR is speech-only format. Music converted to AMR will sound distorted and low-quality. Use MP3, AAC, or OGG for music.

Convert AMR to M4A or MP3 first. iPhone does not natively support AMR playback. After conversion, the file will play normally.

AMR-WB (Wideband) is an enhanced version with better quality, using 16 kHz sample rate instead of 8 kHz. It is used in HD Voice calls.
