What is a GSM file?

GSM is a speech compression format based on the Global System for Mobile Communications. It was developed to optimize audio transmission over mobile networks, focusing on intelligibility rather than fidelity. GSM audio is often encoded at 13 kbps, using the Full Rate speech codec defined by the ETSI standard.

GSM is used in VoIP, voicemail systems, and older mobile networks. While it's not suitable for music, it remains relevant for speech-focused applications in low-bandwidth environments.

How to open GSM files

GSM files can be opened with Audacity (with FFmpeg), VLC Media Player, and SoX. They're often found in VoIP and legacy mobile applications.
