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?

MP3,WAVand AAC(ADTSandADIFvariants) container formats do not support multiple audio streams. MP4 (.m4a) and ASF (.wma) container formats technically can support multiple audio streams.Having said that, I have only seen multiple audio streams in
AVI(DivX files with multiple languages),VOB(DVD format with audio in multiple languages) andMKV(audio in multiple languages).
