How to convert AIF to AMR
- Add your .AIF file - drop it in the box above or click to browse.
- Convert it to .AMR in a few seconds.
- Download your new .AMR file.
What to expect
- AMR-NB runs at 8 kHz mono - roughly telephone quality. Stereo, high frequencies, and fine detail in the original
AIFare permanently discarded. - The conversion is lossy and irreversible; keep your original
AIFfile because convertingAMRback will not restore the lost quality. - Most desktop media players cannot play
.amrfiles reliably - VLC is a safe choice for playback testing.
Frequently asked questions
Why does my audio sound bad after converting to AMR?
AMR is a speech codec that models the human voice and discards everything outside that range, so music, instruments, and stereo content all degrade heavily. This is a fundamental limitation of the format, not a settings problem.
Should I use AMR for music files?
No - for compact lossy audio use AAC or MP3 instead. AMR only makes sense when a specific device or app demands it.
What is the difference between AMR-NB and AMR-WB?
AMR-NB (narrowband) samples at 8 kHz and offers the widest device compatibility. AMR-WB (wideband) samples at 16 kHz and sounds slightly better, but not all devices or apps accept it.
Can I convert AMR back to AIF?
You can reverse the conversion with FFmpeg or a GUI tool, but any quality lost during the AMR step is permanently gone - the restored
AIF will not match the original.Programs that convert AIF: Switch Audio File Converter Software · Freemake Video Converter · WavePad · Tiny Audio Converter
