What is the difference between AU and MAT4, and why should I convert?

AU is an older Sun Microsystems audio format used in Unix environments, known for simple PCM or u-law encoding. MAT4 is a modern, more efficient audio format offering better compression and broader support across current media players and devices. Converting ensures compatibility and reduces file size.

Does converting AU to MAT4 preserve audio quality and metadata?

Yes. The converter maintains the original sample rate, bit depth, and channel configuration during transcoding. Metadata such as artist, album, and title are copied over to the MAT4 file. If the source AU uses lossy compression like u-law, existing artifacts remain; for linear PCM AU files, you can opt for lossless MAT4 encoding to retain 100% of the original audio data.
