Hey everyone, I have multitracks for several songs. Each song has a guitar.ogg, rhythm.ogg, and song.ogg, and I was wondering if it was possible to combine them all (without a loss in quality) into one .ogg file (to compile the entire song into one file). What I've done with a couple is import the three tracks into Audacity and exported as WAVE then FLAC Frontend'ed them. Of course, this causes the files to be much larger than they should/could be.
Moderation: Changed "Combining" in topic title to "Mixing".
Full Version: Mixing multiple Vorbis files into one track
I don't believe you can mix files to a new Vorbis file without re-encoding.
Hrm, well then I suppose my best option would be to export it as MP3 or Vorbis? My goal is to combine the three parts into one file without re-encoding (well this is out of the picture since its supposedly not possible) and no loss in quality (since I have to re-encode, I want a file closest to the originals as possible). What would you guys recommend I do to achieve that? If you have any questions, or need me to explain something more clearly, just ask 
Do you have the original, lossless music files? How did you get each sound? Did you record them? Or did you get the sounds from someone else?

If I remember correctly the latest version of Sony Soundforge works with ogg files. You should be able to use that to import each individual track and combine them into one single file which you would then be able to save. I don't know if that would involve any kind of re-encoding though and I don't know what bitrates Soundforge supports. And it's not cheap about $150 IIRC.

No, I only have the three Vorbis files, no lossless files (unfortunately). Let's not discuss how I came into them (I must respect the Terms of Service). I suppose its not possible then without a re-encoding?
In terms of how the encoded information is stored, a simple 'additive' process to merge the encoded files is, unfortunately, not possible. I think the process you first described is really all that is available.
Doesn't ogg support "chained bitstreams" by spec., which are created by simply joining the files together? In a DOS windows: copy /b a.ogg + b.ogg + c.ogg joined.ogg

Certainly, but I believe the OP is wanting to merge them as in a multitrack recording.
Ah, sloppy reading... Then surely reencoding is required.
Okay well thanks a lot guys for clearing this up for me!
