Hi,
1.04.35 FMOD Designer tool has pretty much only one option for compressed sound on PS3 and that is MP3. In FMOD Ex docs IMAADPCM is mentioned as supported format but I don’t see option for it in FMOD Designer tool.
In one of the recent topics in FMOD EX forum was mentioned that you guys are waiting on AT3 format from Sony.
Can you tell me what are your plans about other compressed audio formats for Playstation 3 in FMOD Designer tool ( ADPCM, AT3 .. atc )

What we’re trying to do is stream multichannel compressed audio. What would be the best way to go about this?

[quote:2oeh3yat]Man, I can’t wait for multichannel support in MP2 and XMA encoded banks. That’s going to be the best thing ever. Well, that and gapless looping in MP2 files [/quote:2oeh3yat]

Agreed! With the right kind of support, we will be able to accomplish great things in the realms of interactive and reactive score implementation.

If you’re using FMOD Designer, the best thing to do is use a program like Adobe Audition to combine the separate tracks into a single multi-channel wav file and then create an Event out of that wav. In my experience, FMOD handles up to 6 channel wav files. If you’re not using FMOD Designer, you can use FSBank to create an fsb file using the Interleaved setting. In both cases, you are currently limited to ADPCM or PCM, as mutli-channel support in MP3, MP2, and XMA is still pending (AFAIK).

[quote="brett":p8in5my9] We do support at3 for streams only though, and won’t remove that. It’s just the realtime sound fx that are the issue right now.[/quote:p8in5my9]

Is streaming at3 supported from FMOD Designer? If so, how do I set up an at3 streaming bank (My current options in Designer on PS3 seem to be MP3/MP2/ADPCM/PCM).

Ryan.

Has AT3 support been added yet? I am interested in getting my AT3 format sounds playing on the PS3.

Thanks,
Kyle

You could look into Ogg Vorbis. I haven’t tried multi-channel myself, but according to the FMOD docs this is supported.

Sony don’t support at3 any more, and neither do we. The available formats are the ones you listed.

Gapless mpeg looping is now available, as is multichannel mp3 streams. Just to follow up on this old thread.

Sony themselves have dropped support for AT3 so we are as well. (https://ps3.scedev.net/forums/thread/11954)
We just added mp2 support for low memory overhead and better codec speed, and we will be adding seamless looping with multichannel mpeg support soon as well.

We do support at3 for streams only though, and won’t remove that. It’s just the realtime sound fx that are the issue right now.

So using Adobe Audition, I’d export as a ProLogic II ADPCM or PCM wav file, then take that file and create an event with it? Is that correct? How does the interleaved setting on FSBank help me in this situation?

Is multichannel mp2 supported as well? Or is that still pending?

Right now, the PS3 options in FMOD Designer are PCM, ADPCM, and MP3. Neither MP2 or AT3 are selectable. Is that because of missing functionality or is it just an oversight?

You open the Surround Encoder (View->Surround Encoder), map the tracks of music to channels in the surround, and then hit the export button, exporting as a single interleaved wav file (16 bit). You import that WAV file into FMOD designer.

In my case, I put the drums into stereo L/R, the lead into stereo Ls/Rs, the bass into the LFE, and the rhythm into the center channel. We’re doing rock type music, so that works for us, but a different type of music might suggest a different approach.

BTW – When you assign something to the LFE channel in the Surround Encoder, make sure to turn the sub all the way up or you won’t hear that track in your music.

FSBank won’t help you if you’re using FMOD Designer. At least, not yet. I’ve put in a request that FMOD designer be able to import interleaved FSB files, but they haven’t gotten around to it yet.

multichannel mp2 is not available yet, just pcm/adpcm/mp3. It will probably come in 4.09 after things settle down and we can update 4.07 to stable branch.

MP2 will be available in our next release and, as mentioned in the above post, AT3 has been dropped.

Okay cool, so Audition can export a true 6 channel interleaved wav file as opposed to matrix encoding a surround mix to a two channel file. That interleaved wav file is supported by FSBank when using the interleaved setting. However, the interleaved setting is not yet available in FMOD Designer. I just took a look in Nuendo and it looks like Nuendo can create interleaved wavs as well. Thank you for the help.

This thread is 4 years old, in the future feel free to start a new thread in preference to replying to old ones. Things have changed quite a lot since this thread was last touched, in response to your question itself: yes MP3 can seamlessly loop. We do support MP2 on all platforms except PS3. Also if you haven’t seen any activity on your question after a week, give it a bump (empty reply) to push it back to the top, someone will get to it. :)

For anyone else wanting to use mp3 compression in the interactive music section, I wanted to point out that, although it works a lot of the time, looping and stitching of segments together can often have pops/seams (no matter how much I tweak the tempo or the source wavs). However, I haven’t had any problems with looping events using mp3 compression (not sure why it’s only a problem with interactive music). I was informed that it’s impossible to predict which songs will not loop/stitch together seamlessly, so I opted to use ADPCM for music on a recent project (fortunately my file size constraints weren’t too restrictive). Going forward, I’m told that CELT will help alleviate the problem, but I haven’t tested that yet. I should also mention that this mp3 issue also shows up on the PC.

Is an additional license required for (FMOD user) MP2 useage, or do you already have patent licenses in place ?

That’s almost right. FSBank is an alternative to FMOD Designer. If you are using FMOD Designer, you should import the wav directly, no need to run it through FSBank. In fact, if you run it (or anything else) through FSBank and import the generated .fsb into Designer, it won’t work, which is what I was saying in my previous post.
