Source format
MP2 is a compressed audio format from the MPEG-1 Audio Layer II standard. It was widely used in broadcasting, digital radio, older video workflows, and some archival audio systems because it offers smaller files than uncompressed audio while remaining relatively simple to decode. MP2 is still encountered in legacy media, transport streams, and professional audio pipelines where compatibility with older equipment matters.
Target format
W64 is the Wave64 audio container format developed by Sony as an extension of WAV for files larger than the 4 GB limit of standard RIFF/WAV. It is used mainly in professional audio production, post-production, and archival workflows that need very large, uncompressed audio files. W64 supports long recordings and high sample rates, and it is often chosen when standard WAV is too limited.
How to perform the conversion
The most reliable way to convert MP2 to W64 is to decode the MP2 audio and save it as uncompressed PCM inside a Wave64 container. A practical desktop tool for this is FFmpeg, which supports both formats.
- Install FFmpeg on your computer.
- Open a terminal or command prompt in the folder containing your MP2 file.
- Run a command such as
ffmpeg -i input.mp2 -c:a pcm_s16le output.w64. - If you need higher precision, you can use 24-bit PCM instead:
ffmpeg -i input.mp2 -c:a pcm_s24le output.w64. - Check the resulting file in an audio editor or player that supports Wave64.
If you prefer a simpler workflow, you can also convert the file on 101convert.com for free without installing any software.
Notes on quality and compatibility
This conversion is lossy to lossless-container: MP2 is already compressed with audio loss, and converting it to W64 does not restore the original quality. The output will be a larger uncompressed file, which is useful for editing but not for reducing size. For best compatibility, use PCM audio in the W64 container, since some tools may not support compressed audio inside Wave64. Also note that W64 support is less universal than standard WAV, so confirm that your target software can open .w64 files before converting.
