About GSM Files
A .gsm file is an audio file saved in the GSM 06.10 format, a speech compression standard developed in Europe for the Global System for Mobile Communications (GSM) network. The format uses lossy compression optimized for human speech, making it efficient for transmitting voice at low bitrates while maintaining intelligibility. GSM files were commonly used in telephony applications, voice mail systems, and early mobile communications, where small file sizes and fast transmission were critical.
The GSM format gained popularity in the 1990s alongside the adoption of mobile phones, and US Robotics later supported it for use in modem-based voice applications. While it is less common today, .gsm files may still appear in legacy systems, VoIP software, or archived telephony recordings.

Converting GSM Files
You can convert .gsm files to other formats to improve compatibility or quality:
- Converting to MP3: Expands compatibility with most devices and players, though it applies another layer of lossy compression, which can further reduce audio clarity.
- Converting to AAC: Offers better compression efficiency than MP3 with similar audio quality, especially on Apple devices, while keeping file sizes smaller for easier sharing and playback.
