How do I convert GSM to ALAC with LetsConvert?

Upload your GSM file to LetsConvert, select ALAC as the output format, choose your preferred sample rate (e.g., 44.1 kHz) and bit depth (16 or 24 bit), then click Convert. Once finished, download the .m4a file with ALAC encoding. No need to set codec parameters—LetsConvert handles the decoding and encoding automatically.

Why should I convert GSM to ALAC instead of keeping GSM?

GSM is a lossy telephony codec (13 kbps, 8 kHz) used for voicemail and phone systems, while ALAC is Apple's lossless codec for high-fidelity audio. ALAC files play seamlessly in iTunes, Apple Music, and most modern media players, offer better metadata support, and are ideal for long-term archiving. Keep in mind that converting GSM to ALAC won't add missing frequencies, but it prevents further quality degradation and makes the file more universal.

What happens to the audio quality and technical attributes during GSM to ALAC conversion?

The converter first decodes GSM to uncompressed PCM at its native 8 kHz sample rate. It then encodes that PCM into ALAC without any lossy compression. If you choose a higher sample rate (e.g., 48 kHz), the audio is up-sampled, which fills in zeros rather than restoring detail. Channel count is maintained, but since GSM is mono, the output will be mono unless you explicitly upmix. Bit depth is typically 16-bit, matching the PCM intermediate. Metadata like album/title tags may be preserved if present in the source GSM file.
