Hello everyone. I’m new at the forum, but this seems to be the best place to get solutions to issues concerning Fmod.

I’m involved with Resolution Interactive AB that are making games for the iPhone and using Fmod. I’m the sound/music guy, and we’ve decided to use multi-channel music in order to make the soundtrack somewhat interactive.

There’s just one problem – we need a 6-channel .ogg file(like in the multi-channel music example that comes with the designer), and I don’t know how to export into multichannel ogg vorbis.

I can make a 6-channel .wav or .ac3 -file with all the channels and levels right, but I have no clue of how to convert it into an .ogg -file! So I guess there are 2 ways of solving the puzzle, either finding the software that allows me to export 6 individual mono-channels(or 3 stereochannels) into the multichannel ogg, or to find a converter that is able to do this from an existing file.

If any of you’ve got the know-how, please help out!

Best regards / Josef Falkensköld

For iPhone use I would highly recommend you do not use ogg if at all possible. It is one of the most CPU intensive formats to decode. Switching to something less expensive like ADPCM or MP2 would be beneficial.

If you want to create a multichannel file from individual mono or stereo files you could use the FSBankLib API on the Mac or FSBankEx tool on Windows (if you have access to a Windows machine).

Just a little note, I used a Mac app call ‘TwistedWave’ to create the 6 channel ogg. It’s a nice and cheap little editor, which makes constructing and reordering multi-channel files really easy.

cheers,
