Hi,
I attached a really small patch I created to start a soundfile when a face is infront of the camera.
I use windows, so I use Processing to detect the face. That is the [OSCroute /face] object. /y is another parameter (influenced by a color detection) that should later controle the volume.
If there is a face, than the value of 1 is transferred to /face and the tabplay should start and loop. If there is no face the value of 0 is transferred, but I don`t know how to stop a play. It should stop directly and not after the ongoing play is finished.

And moreover, it should stop, if the value of 0 is 2 seconds constant, because the face detection is not always stable.

And another problem, I don´t know how to use the onebang correctly.

Can you help me? That would be so great!

Thanks a lot,
Anna

i do believe the message [stop( will stop it use a metro counter that counts up to two, [select 2] - bang stop. whenever motion (or whatever the signal is) is detected, send [0( to the counter to reset it. and a bang to the metro to reset that.

one bang will only emit a maximum of one bang through if banged through the left inlet. until it is reset with a bang in the right inlet.

hope that helps

Thanks for your help, but I have still problems.
I uploaded a rar file that includes a sample and the pd patch.

I left out the counter thing, because I didn´t make the stop sample work.
Any suggestions how to solve it?

Thx,
Anna

This doesn't solve the 2-second zero rule, but it stops the playback when 0 is received.
Hope this helps a little...

Thanks a lot, that helps so much.
But I have a question: How does the change object work?
I think it changes the 0 at the ende back to 1 to start the new trigger, but how?

So, I try to figure out how to include the counter.

Thanks a lot!

The change object only lets a numeric value thru when it's a different value than the previous one. I can imagine that your face-detection sends a continuous stream of 1's when it's detecting, you only want the first positive trigger the sample.
