How do I convert an M4A file to W64 using LetsConvert?

Upload your M4A file, choose W64 as the target format, and set the PCM audio parameters (sample rate and bit depth). Click Convert, and the tool decodes the M4A to an uncompressed W64 file. You can then download it for playback or import it into a DAW like Sound Forge or Pro Tools.

Why convert M4A to W64 instead of using M4A directly?

M4A is compressed with AAC, which loses quality and may not be natively supported by older audio editors. W64 stores uncompressed PCM, so it avoids re-compression and is fully compatible with professional editing software. It also supports files over 4 GB, which is useful for long recordings.

What happens to audio quality and metadata when converting M4A to W64?

The conversion decodes the M4A stream to PCM without altering sample rate or channel count. However, any compression loss from AAC is permanent—W64 cannot restore it. Metadata like title and artist may be carried over, but W64's metadata support depends on the software; we recommend checking the output file's tags after conversion.
