Complete Guide: AMR to MP3 Converter
Everything you need to know about using this tool effectively
The AMR to MP3 Converter decodes AMR voice recordings and re-encodes them as MP3. MP3 is supported by every device and platform, making it the easiest format for sharing Android voice memos or call recordings anywhere. All conversion runs in your browser using FFmpeg via WebAssembly.
AMR (Adaptive Multi-Rate) is the speech codec used by Android devices for voice memos and call recordings. It has limited support outside Android, making it difficult to share or play on other devices. This tool uses FFmpeg to decode AMR and produce an MP3 file that plays on any phone, computer, or media player.
Share voice memos on any platform
Convert Android AMR voice memos to MP3 to share via email, messaging apps, or cloud storage with recipients who use any device.
Upload call recordings online
Call recorder apps save in AMR. Convert to MP3 to upload recordings to transcription services, cloud storage, or sharing platforms.
Play Android recordings on iPhone
iPhones cannot play AMR files natively. Convert to MP3 to send and play voice recordings on Apple devices.
Embed voice recordings in presentations
PowerPoint, Google Slides, and similar tools accept MP3 but not AMR. Convert voice memos to MP3 before embedding in a presentation.
Back up voice recordings
Convert AMR recordings to MP3 for long-term storage in a widely supported format that will remain accessible regardless of future software changes.
Transfer AMR file to your computer
Copy the AMR file from your Android device via USB or cloud storage.
Upload AMR file
Click to browse or drag and drop your AMR file into the upload area.
Convert
Click Convert to MP3. FFmpeg decodes the AMR and encodes the result as MP3.
Download MP3
Download your MP3 file for playback or sharing on any device.
AMR is optimised for speech. Voice recordings convert well, but AMR captures music poorly due to its narrow frequency range.
Converting AMR to MP3 applies two rounds of lossy compression. The quality is limited by the source AMR.
For transcription purposes, WAV is preferable to MP3 as input for most speech-to-text services.
AMR files from call recorder apps may be very short and produce very small MP3 files.
Keep your original AMR files in case you need to re-convert.
Why does AMR audio sound like a phone call?
AMR-NB has a frequency range of 300–3400 Hz, which is the same bandwidth as telephone audio. This is a characteristic of the source recording, not a conversion artifact.
Does converting AMR to MP3 lose quality?
Yes. Both AMR and MP3 are lossy formats. The conversion applies a second round of compression on top of the already-compressed AMR source.
Are my files uploaded to a server?
No. FFmpeg runs in your browser via WebAssembly. Files are processed locally.
Why does the first conversion take longer?
The first conversion loads the FFmpeg WebAssembly binary. This takes a few seconds. Subsequent conversions are immediate.
Where are AMR files stored on Android?
AMR files from the default Voice Recorder app are typically stored in the Recordings folder or in /storage/emulated/0/Recordings/ on the device's internal storage.
