A GSM file is an audio file format primarily used for voice data, particularly in telephony applications, originating in Europe. It uses the GSM (Global System for Mobile communications) standard for encoding audio, resulting in a compressed file well-suited for storing telephone conversations and voice recordings.
Key Characteristics of GSM Files:
- Purpose: Primarily designed for storing speech and voice data efficiently.
- Encoding: Employs the GSM audio codec, which is a lossy compression algorithm.
- Usage: Commonly used for recording phone calls, voice messages, and other speech-related audio.
- File Extension:
.gsm
Technical Details:
The GSM codec prioritizes bandwidth efficiency over high fidelity, making it suitable for environments with limited bandwidth, such as mobile networks. While it effectively compresses audio, the compression results in a noticeable reduction in audio quality compared to uncompressed formats.
Programs That Can Play GSM Files:
Many audio players and editing software support the GSM format, including:
- VLC Media Player
- Audacity (with the optional FFmpeg library installed)
- Media Player Classic
- Switch Audio File Converter
Summary
In essence, a GSM file is a compressed audio file format tailored for voice recordings, particularly phone calls, where efficient storage and transmission are prioritized over pristine audio quality.
