How do I convert a W64 file to AU using LetsConvert?

Upload your W64 file, choose AU as output, and optionally select a codec (PCM for lossless or mu-law/A-law for compatibility), then hit Convert. Your AU file will retain the original PCM sample rate and channels when using lossless mode.

Why convert from W64 to AU instead of keeping the original file?

W64 (Sony Wave64) is a 64-bit RIFF container designed for large multichannel audio in broadcast and DAWs. AU (Sun/NeXT) is a compact Unix-era format with near-universal support in Java and classic audio players. Converting makes audio accessible to legacy systems and can reduce file size when using compressed codecs.

Does the conversion preserve sample rate, bit depth, and channels?

In lossless mode, PCM sample data, bit depth (16/24/32-bit), sample rate, and channel mapping are copied without re-encoding. If you opt for mu-law or A-law, the audio is converted to 8-bit companded PCM, which alters dynamic range but ensures compatibility with telephony and early Unix software. Metadata is typically discarded, so save important tags separately.
