What is a .GSM file?

The GSM file format is an audio format that uses the GSM 6.10 lossy compression algorithm. It is designed for voice audio compression in telephony systems, providing good compression ratios and acceptable quality for voice data.

Background

The GSM file format emerged as a standard for compressing voice audio data in mobile communications. It is widely used in telephony systems due to its ability to compress audio data effectively while maintaining clarity in voice transmission. The format is particularly optimized for the human voice, making it less suitable for music or other complex audio. GSM files are often used in voicemail systems, audio messaging, and other telephony applications. Despite its specific use case, the format can be opened and edited with several audio software applications, making it versatile for developers and audio engineers working with telephony systems.
