How do I convert a MAT4 file to AU using LetsConvert?

Upload your .mat4 file, choose AU as the target format, and click 'Convert'. For batch conversion, select multiple MAT4 files. The tool automatically decodes the MAT4 matrix encoding and encodes the audio into AU's uncompressed PCM format. You can adjust sample rate and bit depth before conversion if needed. Once finished, download the .au files to your device.

Why should I convert from MAT4 to AU instead of keeping the original format?

MAT4 is a niche format used in digital audio workstations for matrix-encoded multi-channel audio. Converting to AU (Sun Audio) makes the file playable on legacy Unix systems, Java-based audio apps, and embedded players without third-party codecs. AU files are also uncompressed, so the conversion avoids any generation loss—making it ideal for archival or interoperability.

How does the conversion handle channel layout and metadata from MAT4 files?

The converter decodes each MAT4 track and maps its channels to AU's multi-channel PCM layout. Sample rate and bit depth are preserved exactly as in the original, with no dithering or resampling by default. Matrix metadata used by MAT4 for spatial positioning is not supported in AU, so it is discarded; however, the PCM audio data is unaltered, ensuring you retain the full dynamic range and timing.
