Hi
I don't really know which is the best forum to post this so I'm going to try a few [mods - apologies for the duplication]

I have a really long shot of a laser cutting into stone and I have a sort of buzzing / hissing sound effect I want to use but it is pretty constant all the way through... so what I want to do is play the clip and use some software [I know I can get access to soundforge and ACID, maybe something else is what I need though] to twiddle some sort of knob to change the volume / envelope or something [don't know much about sound] so that it appears to get louder or hissier or something when the laser is going more slowly across the surface - and record the knob twiddling so it can be played back / rendered to wav... I just need to tie the audio and visual together somehow really.

I have a custom 'slowness' attribute on a locator in maya which I could bake out and use that as a control if that's possible without writing custom software. It's too long a shot [5000 frames] to bake the graph and manually use it as a guide to keyframe in say after effects

Hope that makes sense
thanks for reading

I am not to sure what you want to do, let me clear this up. Do you want to create a sound effect outside of maya then import into maya so you can animate to the sound?

If this is what you want maya has a sound import but the catch is it has to be wave. Just goto File>Import>Find your sound file. Next in the timeline right click on it and goto sound> your sound file. This ensures sound in maya so you can sync up lip sync. You can scroll the timebar and the sound will play. Doing a playblast this will enusure the sound is rendered out as well.

O ya one more thing if you want to play with sound make sure that your playback speed is set to realtime PAL24 fps or NTSC30 fps.

Hope this helps.

Thanks dragonP but tthat's not what I'm trying to do... I have already rendered and comped my scene and now I'm working on sound effects for it. But I saw a friend last night who is a musician and he's going to help me with it, so hopefully problem solved.
thanks anyway
