Global System for Mobile (GSM) is an audio format that the European Telecommunications Standards Institute (ETSI) created for use with European cell phones. It is a compressed format that stores audio encoded at a bitrate of 13 Kbps.

Because the GSM format is primarily used in telephony, most GSM files contain telephone conversations. However, GSM files may also contain music or other audio, saved at the level of quality you'd expect from a telephone conversation.

How to open a GSM file

You can open a GSM file with VideoLAN VLC media player or FFmpeg, to play or convert the audio it contains.

How to convert a GSM file

VideoLAN VLC media player, NCH Switch, SoX, and FFmpeg can all convert GSM files to more common audio formats. For example, VLC can convert GSM files to the following formats:

  • .MP3 - MP3 Audio
  • .FLAC - Free Lossless Audio Codec
  • .OGG - Ogg Vorbis Audio
