How do I convert AMR to GSM?

Upload your AMR file, select GSM as the output format, and click Convert. Our tool will re-encode the audio using the GSM full-rate codec. Once done, download your .gsm file. You can process multiple AMR files in batch if needed.

Why should I convert AMR to GSM?

AMR is a bandwidth-efficient codec used in modern mobile recordings, while GSM is a legacy full-rate codec found in older phones, voice mail systems, and embedded devices. Converting AMR to GSM ensures playback on such legacy hardware. GSM’s fixed 13 kbps bitrate can also be useful when a predictable file size is required.

What happens to the audio quality during AMR to GSM conversion?

Both AMR and GSM are lossy speech codecs operating at 8 kHz sample rate. During conversion, the audio is decoded from AMR and re-encoded to GSM full-rate at a fixed 13 kbps bitrate. This means the original AMR quality is lost in the transcoding process; you won't get a bit-perfect copy, but speech intelligibility is preserved for compatible devices.
