Just got this working, it is very cool. Not a single click or noise, just absolutely perfect looping. A lot of websites say it is not possible due to restrictions of the format but we’ve done some cool stuff to make it possible.

sweet! :) that just chopped a nice big chunk out of our memory useage. fantastic stuff. – thanks Brett.

Is this something that requires FMOD Designer, or will we also be able to just load up a file with System::createSound("blah.mp3", FMOD_LOOP_NORMAL, etc.) and then playSound() and it’ll loop seamlessly?

you have to use fmod designer or fsbank, most of the work is on the encoder side. You need an encoder that knows about looping. most dont.

Any ETA on this one? Is it a Tool only thing (fmod designer)? Would there be any changes on the Runtime?

I said next release,, so its this week, probably tuesday.

The decoder side has nearly no change, just a very small one to stop fmod resetting the codec every time it does a seek, which caused a tiny click.

Just so I understand… So lets say I have a complex (fmod designer) loop heavy event like Greg’s car engine in 44.1kHz 16bit, 48kHz 32bit or whatever format… after exporting (mp3 or mp2) all the loops will loop perfectly?

a few questions come to mind…

will it be possible to preview/audition the loop (encoding), before exporting?
will it also be possible to put already made mp3 or mp2 (loop) files and bypass the encoder?

  • not related
    is there a (editing) software that makes an mp3/mp2 loop without converting the audio data to wave (leaving the mp3/mp2 data intact, just adding loop points)?

Yes, in fact i used greg’s car models to test this on, and his car sound loops play absolutely perfectly. They sound awesome.

The only way to preview is to use audition client on 360 (for xma), or use eventplayer after exporting the data with fmod designer. (associate .fev with event player in windows and just double click on the fev)

You can’t put ‘already made mp3 loops’ because there is to my knowledge nothing that loops mpeg data perfectly like fmod’s encoder. This is not a common thing. Many websites say it is impossible to create gapless-loop perfect mpeg data, we have done it through several modifications to the encoder, it is an encoder thing, not an decoder thing as I think i’ve said a few times.

To answer you last question, no there is no editing program that can just ‘loop mpeg data’. Editing programs always work in pcm.
