Source format overview
MP2 is the MPEG-1 Audio Layer II format, an older compressed audio format used in broadcasting, digital radio, and some legacy video workflows. It is a lossy format, meaning some audio data is discarded to reduce file size. MP2 is still encountered in TV, radio, and archival media, especially where compatibility with older hardware or standards matters.
Target format overview
VOX is a telephony audio format commonly associated with Dialogic ADPCM audio. It is designed for speech and voice recordings rather than high-fidelity music. VOX files are typically very small and are used in voice prompts, IVR systems, call-center applications, and legacy telephony software. The main advantage of VOX is compact size for spoken audio, but it offers limited fidelity and very little metadata support.
How to perform the conversion
The most reliable way to convert MP2 to VOX is to use FFmpeg, a powerful command-line multimedia tool. Because VOX is a specialized format, conversion usually requires setting the correct codec and audio parameters for speech-oriented output.
- Install FFmpeg on your computer if it is not already available.
- Open a terminal or command prompt in the folder containing your MP2 file.
- Run a conversion command such as
ffmpeg -i input.mp2 -acodec adpcm_ima_ws -ar 8000 -ac 1 output.vox. - Check the resulting file in the target application or with an audio player that supports VOX.
If your VOX target system expects a different ADPCM variant, you may need to adjust the codec. In some workflows, mono audio at 8000 Hz is preferred because VOX is often used for speech playback.
You can also convert the file on 101convert.com for free, without installing any software.
Notes on quality and compatibility
MP2 to VOX is a lossy-to-lossy conversion, so audio quality will decrease, especially for music or complex sound. VOX is best suited to voice recordings; stereo audio, wide frequency content, and high sample rates are usually unnecessary and may not be supported by the destination system.
Compatibility can vary because VOX is not a single universally standardized consumer format; some software expects a specific ADPCM flavor or raw headerless data. If the converted file does not play correctly, try changing the codec or sample rate, or consult the requirements of the receiving telephony system.
