The .W64 file is a Sony Wave64 Audio file. It was created to solve the strict 4GB size limit of the standard WAV format by using 64-bit headers. This allows audio engineers to record multitrack sessions, long podcasts, or live events that run for hours without splitting files. You can open these files with professional tools like Steinberg WaveLab, Audacity, or Vegas Pro.
The major downside of the .W64 format is poor consumer compatibility. Standard media players, smartphones, and web browsers cannot natively play .W64 files. Because they hold raw, uncompressed PCM audio, the file sizes are massive, often reaching tens of gigabytes. This makes them incredibly expensive to store and nearly impossible to share over email or standard cloud links.
To share, archive, or listen to these recordings easily, you must convert them. For web delivery and mobile playback, convert .W64 to MP3 or AAC. For high-quality archiving that takes up less space, convert to FLAC, which provides lossless compression. If you need standard DAW compatibility and the file is under 4GB, convert to WAV.
