Managing Sound Frequency

[Blotch]

Hello, Is there a way to control the sound frequency to a particular sound? So when that sound is made it triggers a video? Thank you

[Skulpture]

Yes using the sound frequency watcher.

Thank you ! If i had several instruments around the room would it be specific  to only pick up the sound of that instrument if i set the frequency correctly ?

If your instruments produce just single(or clear range) frequency then why not. It should work. You can tweak freq width and slope to tune on one instrument. 

But if you talking about musical instruments then I think you will have difficulties.
