Source format: MP2
MP2 (MPEG-1 Audio Layer II) is a compressed audio format that was widely used in broadcasting, digital radio, and older video production workflows. It is still found in some TV, DVD, and archival media files. MP2 offers decent audio quality at moderate bitrates, but it is less efficient than newer formats such as MP3 or AAC.
Target format: GSM
GSM audio usually refers to the GSM 06.10 speech codec, a very low-bitrate format designed for telephony and voice-only recordings. It is optimized for speech, not music, and produces small files with limited fidelity. GSM is mainly used in legacy phone systems, voicemail, and some voice-processing applications.
How to perform the conversion
The most reliable way to convert MP2 to GSM is with FFmpeg, which supports both formats and is available on Windows, macOS, and Linux.
- Install FFmpeg if it is not already available on your system.
- Open a terminal or command prompt.
- Run a command such as
ffmpeg -i input.mp2 -ac 1 -ar 8000 -c:a gsm output.gsm.
This command does the following:
-i input.mp2selects the source file.-ac 1converts the audio to mono, which is appropriate for GSM speech encoding.-ar 8000sets the sample rate to 8 kHz, the standard rate for GSM speech.-c:a gsmchooses the GSM audio codec.
If you prefer a graphical workflow, you can also use desktop audio tools that support FFmpeg-based export, but FFmpeg is usually the simplest and most dependable option. You can convert the file on 101convert.com for free, without installing any software.
Notes on quality and limitations
MP2 to GSM is a lossy-to-lossy conversion, so some quality loss is unavoidable. Because GSM is a speech codec, music, stereo content, and full-range audio will sound heavily degraded after conversion. For best results, use this conversion only when the destination must be a voice-only GSM file.
Also note that GSM support is limited in modern players and editors. If compatibility is important, consider whether a more common voice format such as WAV or MP3 would better suit your needs.
