What is a .GSM file?
GSM files are audio files saved in the Global System for Mobile (GSM) format, which compresses voice recordings using a lossy codec optimized for telephony. Unlike high-fidelity formats like WAV or APE, GSM focuses on reducing file size while maintaining clear speech, making it ideal for phone calls, voicemail, and other voice communication applications. These files are commonly used in mobile networks, call recording systems, and older telephony equipment.
You may encounter GSM files when saving recorded phone calls, exporting audio from VoIP or PBX systems, or sharing voice messages across mobile networks. File Viewer Plus can play GSM files and convert the audio to formats like MP3 or M4A at different bitrates and frequencies, allowing them to be used on a wider range of devices and media players.
