I'm a student doing an MA in music tech and I am building an installation art piece and need advice on setting up a simple MAX MSP patch.

Basically, what i want to happen is for a microphone to pick up sound in a room. When the decibel level in the room reaches a certain threshold, I want to trigger playback of a piece of music. 

Simple. I want the playback of the music to last for 3 seconds every time the threshold is reached, but play back constantly if the noise level remains above the threshold.

Please please please can someone who knows how to do this get in touch and help me out, it will only take a moment of your time and will help me out tremendously.

I just had to do a similar thing, although I only had to trigger a MIDI note

of a specific duration every time the input reached the threshold.

I'm very new to msp but have used max for some time so i don't even know how

But this little example which I have tried to adjust for your needs could do

the trick, especially if you have a sampler to trigger with a MIDI note...

If not, then, you can combine it with a sampler in MSP.

It delays the flushing of the MIDI note with 3 seconds when the sound goes

below the threshold, in effect holding the note as long as it is over the

threshold and only playing for 3 seconds if the intensity just peaks once.

of a specific duration every time the input reached the threshold.
I'm very new to msp but have used max for some time so i don't even know how
to play samples yet!

could someone comment this code so that it is easier to understand what is being done here.

i have a similar project and this would be great information to have.
