Problem triggering audio files with kinect!

in Integration and Hardware • 2 years ago

Hello!
Okay... having major struggles with this

I am triggering sounds with motion on kinect. The first problem was it using AudioSample which triggered the sound over and over again and didnt stop.

I changed to AudioSnippet which triggered the sound just once, but then would not trigger again.

When using the rewind, play functions does not help (repeats over and over again)...

I then slowed the frameRate down to 0.5 with the rewind and play functions, which gives me the result I want, but the animation slows right down and couldnt find a way to seperate frame rates for sounds and animation

I am new to Processing so im in struggle street, any help will be greatly appreciated..

My Code:

Re: Problem triggering audio files with kinect!

looks great. going to try it out in a bit. also do you think its possible to replace the audio with video? maybe use something like the GSVideo library http://gsvideo.sourceforge.net/

also i had tried to do something with the kinect and sound too. i dont know what yours does but here is a link to what i tried. https://forum.processing.org/topic/video-trigger-using-kinect-simpleopenni-library

Re: Problem triggering audio files with kinect!

1 year ago

yeah I know you can trigger video with it, Im not sure how to do it... I was triggering audio files and frame animations with positions in Up Right Down Left and the diagonals in between... I was taking frames from video and using that instead of triggering a video file, I cant remember why I decided to use that option, I think I originally had difficulty with video files so went with frames....

Good luck, have fun with it... feel free to ask more questions, will help with what I can (I dont have a kinect camera at the moment, but if I get my hands on one will check out that link)
