M4A w skrocie
M4A
Convert to M4A when you need a compact, modern audio file for music, podcasts, lectures, or spoken-word distribution with strong playback support and good metadata handling.
It is an excellent target for listening copies and portable libraries.
For raw editing or mastering, uncompressed or lossless production formats remain better choices.
AU w skrocie
AU
Convert to AU when preserving compatibility with older Unix or workstation software, educational assets, or historical multimedia archives.
In most present-day workflows the practical task is to decode AU content and move it to WAV, AIFF, or a modern compressed format.
Use AU only when downstream compatibility makes it necessary.
