It doesn’t seem like it is currently possible to build interleaved banks via FMOD Designer. Our music is set up in Designer, and it appears that it is therefore impossible to have stereo VAG support on PS2 via the Event API. Am i mistaken?

hi everybody!

i just wanted to implement dynamic music with multichannel wav-files and "channel mix" effect.
i wasted plenty of time to find out, that the maximum fmod could handle was 3 stereo pairs.
loading files with more than 8 channels in fmod designer leads to an error (something like "this is no audio file").
when loading a file with exactly 8 channels and following the designer documentation (page 140; fun with multichannel files), i can audition it correctly. but when i load the project within the game (PC), it sometimes ends up in painful loud distortioned sound or nothing at all (depending on the parameter).
i’ld be happy if somebody might tell me what i’m doing wrong, or if i don’t, anybody who finds that bug.

nevertheless, aweful library. i love it

thx in advance

p.s.: designer 4.11.05; fmodex 4.11.05

Thanks acrosby thats a useful link, we’ll keep that in mind when other people ask about it :)

atti, are you using the latest version? i had similar issues, i guess it was related to having multichannel and non-multichannel files in the same bank or something like that.

anyway we are using files with encoded as mp3 with 4 stereo pairs and it’s working now, i believe the fix was put in the release from earlier this month.

edit – duh..i just saw your version number. i’m using 4.11.04 so i guess that the bug is still hanging around somehow.

If you supply fmod with multichannel wave files it will work, it complicates the gui too much to have to supply multiple mono wave files and tell it that they are 1 sound.

I think you can make wavs of up to 32 channels in SoundForge 9.0 too. Just go File-New and select the number of channels.

"loading files with more than 8 channels in fmod designer leads to an error (something like "this is no audio file")."

Is this issue fixed?

Can anyone recommend any good tools for building a 16-channel wave file out of 16 mono wave files (free or cheap tools would be ideal)?
The ones I’ve been able to find so far have only been able to build waves with <= 8 channels.
(We’d like to be able to import interleaved music files with 8 stereo tracks into FMOD designer)

I’m curious as to how this could be implemented in Designer. If we import an interleaved FSB, would each individual channel show up? This would be ideal, as it would allow us to create a really nice dynamic music system based off of events, parameters, and crossfading of channels in streams….

Yes. Designer can now load sounds with up to 16 channels.

FSBankEx supports this (part of the programmers sdk toolset), you can use 16 mono wav files and output. I’m not sure if FMOD Designer supports .fsb files but we can look into it, if it doesnt , it will be a simple tweak to do it.

FSBankEx just requires you to select ‘single interleaved file’ as the build mode, specify a directory with your 16 mono wavs, output the .fsb format as pc/pcm and you will get a 16 channel interleaved file.

yes, you can configure the file type in the wav bank to show up as multiple mono or groups of stereo streams. (right click on the wav in the bank and click channel setup)

then you can slap a channel mixer effect on it, and configure which channels you want, so that you can control each individual stream’s volume independently.

we are using this to crossfade different tracks (essentially, different submixes of a song like drum or ambient parts) that play in sync with eachother, then use fmod parameters to control which tracks fade in and out. works pretty well so far!

(thanx to ben batt from firelight who informed me of how to do this. here is his comment:

"Just a note about the “Channel Mix” effect: you can add envelopes to control more channels from the Effect Properties dialog (accessed by right-clicking on the effect control widget in the event editor view). If you use this, you’ll probably want to look into changing the channel setup of the waveforms you use (right-click on the waveform in the wave bank view) to “3 x Stereo” or similar.")

Last I checked, FMOD Designer didn’t support interleaved fsb’s. You can import them, but it would barf when you tried to build the banks. I would love it if you guys made that "tweak" as it would allow us to be a lot more creative with our audio and would remove Audition as a critical part of our music pipeline.

Thanks, Acrosby. I’ve sent you a PM to discuss further – but my main concern with this approach is that this probably requires the software mixer, yes? I’m guessing the Channel Mix effect wouldn’t work with the Wii or PS2 reduced libraries…so I’m wondering if there is another way to control the volume of each stereo track in an interleaved stream through designer…

2nd vote for this. I assumed that this functionality was already present, but having the ability to use an FSBANKEX built FSB in place of an FSB made in Designer would be a very useful tweak.

This is incorrect, the channel mix effect works on hardware voices on wii and ps2.

I was actually referring to importing an FSBANK generated fsb into a Designer wavebank in the same way that you would import a .wav file. Is that what you mean, too?

Our current pipeline for multitrack music is:
Set of wavs (one for each channel) -> Adobe Audition’s Surround Encoder -> 6-channel interleaved wav -> FMOD Designer.

I would like to replace that Audobe Audition -> multichannel wav step with an FSBank -> Interleaved FSB step, which would both cut a commercial tool out of our pipeline and allow us to do > 6 channel audio.

That is GREAT news. Thanks, Brett!

Yes – exactly agreed. FSBANKEX is currently the ONLY tool I have for multi-channel audio files, so being able to either build them in Designer, or import them would be ideal.

Just wondering if there’s a timeframe for when we might be able to see this functionality (import interleaved FSB into designer)?

If it is far out in the future, I’ll need to change-up the pipeline to incorporate one of these multi-channel WAV tools…

Thanks.

we’ll look into it i’m sure it will only take us a few lines of code to make it work.
