How do I convert a GSM file to CAF?

Go to the GSM to CAF converter page. Upload your GSM file (or drag and drop). Select CAF as the target format and optionally choose ALAC or AAC codec. Adjust sample rate or bitrate if desired. Click 'Convert' and download the resulting .caf file. For multiple files, enable batch conversion.

Why should I convert GSM to CAF?

GSM is a low-bitrate telephony codec (13 kbps) used for voicemail and phone recordings. CAF is Apple's Core Audio Format, supporting high-quality codecs like ALAC (lossless) and AAC. Converting to CAF allows playback on macOS/iOS, editing in GarageBand, and archival with better audio fidelity.

How does GSM to CAF conversion handle audio bitrate, sample rate, and channels?

The conversion decodes the GSM stream to PCM and re-encodes to the CAF codec you choose. With ALAC, the decoded PCM is preserved bit-perfectly, keeping the original sample rate and channels (usually mono). With AAC, you can change bitrate and sample rate, which may alter quality. Any metadata embedded in the GSM file, such as recording timestamps, is transferred if supported.
