How do I convert MP3 to W64?

Click the uploader to select your MP3 file, then choose W64 as the output format. Press 'Convert' and wait for the process to finish. The tool decodes the MP3 to PCM and stores it in a Sony Wave64 container, keeping the original sample rate and bit depth. For multiple files, use the batch mode to convert all MP3s at once.

Why convert MP3 to W64 instead of keeping MP3?

W64 is a 64-bit wave container developed by Sony, commonly used in game engines such as Unity and Unreal. It removes the 4GB file size limit found in standard WAV files and supports high channel counts. Converting MP3 to W64 allows you to use MP3 audio in these professional pipelines. Note that W64 files are much larger because they store PCM audio uncompressed.

What happens to the audio data when converting MP3 to W64?

The MP3 stream is fully decoded into linear PCM, which is then written into a W64 container without any additional lossy encoding. The sample rate, bit depth, and channel layout remain identical to the decoded MP3. Since MP3 is lossy, the original compression artifacts are already present in the PCM data, and the W64 file will preserve them exactly.
