If I may pop in, I don't think
any consumer editors will export true
"multi-track audio" (eg. Track 1 = English (Stereo), Track 2 = Spanish (Stereo)), where you can choose which one to listen to at one time...
Even the $500 Sony Vegas Pro [recently bought out by MAGIX] can't do that, although you can 'trick' any of these programs into retaining the multi-track audio as
"multi-channel" ('5.1 audio'); where you essentially take the English Audio Track output to Channels 1 and 2 (front L and R), and put the Spanish Audio Track to Channels 3 and 4 (rear L and R), etc.
The problem with this, is if you playback the material on a PC with headphones, you will 'hear' ALL of it at once.
[Note: This is fine if you are trying to combine 'videogame recordings and mic input and maybe a Skype input or other audio' - since you WANT to hear 'everything at once' (after adjusting the volumes) - if this is what you are trying to do, you can try a 5.1 audio "hack" of doing it, it just takes a lot of steps (in any video editor), to assign "game L and R" to "Channel 1 and 2, "mic audio L and R" as Channel 3 and 4 (Mono, if you want, since most microphones record in monaural), etc]
If you are trying to use this '5.1 Multichannel "hack" method for full Language Tracks, you can isolate the playback of front and rear speakers if you have it playing on external Speakers or a Mixer/Amplifier that you can turn off the front or the rear [say, on a 'full stereo system' type of setup]; but if you are listening to it from a file with headphones, you'll just hear
both Languages at once (all Channels at one time)...
The only way that I know of, aside from Rendering to a Disc format (eg. BluRay/DVD, where you can put multiple Languages as Full Audio Tracks that you can choose from when listening), is:
Render out your 'main' video and desired audio Track as one output file (or Video as one file, Audio as one file), then Render out your 'other Tracks' as Separate Audio files (WAV/m4a/etc) - and then
Multiplex everything you want all together with a program that will 'assign' true Multiple Tracks within an AVI/MP4/MKV type of file - one that you can choose the different Tracks (eg. Languages) when you are listening to it, like playing it back on a PC, for example.
I might be wrong though, please anyone let me know if I am - I would love to know how to do this within PowerDirector!
