While designing a new feature for a software application that I'm working on, I am attempting to define a table structure for audio files, and I have the following question. Do mp3, m4a, wav, aac, wma, and aiff support multiple streams, and if so how commonly used is the multiple stream feature of each?

Questions on Audio-Video Production Stack Exchange are expected to relate to audio or video recording and production within the scope defined in the FAQ. Consider editing the question or leaving comments for improvement if you believe the question can be reworded to fit within the scope. Read more about closed questions here.
(I'm not your downvoter, but StackOverflow is probably a better choice for this question. Don't know if any of the mods have the powers to migrate it across). Here's my answer anyway:
WAV supports multi-channel audio, although it's not very efficient in terms of disk space. I'm pretty sure MP3 is limited to stereo. I'm not sure about the others, but I would recommend storing each stream in a separate file anyway.
