Need help with triggering audio (newcomer and lost)

November 2, 2011 | 10:19 am

Hey people!

I need to make a program that triggers a random soundfile (from a list of several files) whenever the computers microphone "hears" anything.

So far i can only make MAX play what the computer "hears".

I cant find any answers through searching but something tells me this is quite simple to do.

Sorry for the inconvenience, i hope someone is able to help

Kind Regards

Have you tried ezadc for mic input? or adc~ ?
a problem ive recently overcome too.
fellow rookie!

You mean to choose a random file after a "audio trigger" over your mic? But you don’t want to recognize the speech (like Siri on iPhone 4S), right? So lets say anybody claps in the hands – the next random file is playing etc.?

Yeah i use ezadc – and it picks up the mic. The problem is however that i cant make the input trigger a soundfile – i can only make it play the input back in the headphones. Thanks for the quick reply

Thats exactly what i want to do :) audio trigger that plays when someone speaks or clap their hands etc.

Here is a solution. But I can’t remeber how to convert a signal to bang. This is a TODO in that patch. But you can see the "1" inside the number~ object if you clap. Maybe you have to change the numbers a little bit for your mic. With my Mac Book Pro it works perfect.

I’m sure that the convert-thing into bang is very simple, but can’t remeber…

Now it works! The right outlet of number~ provides the float value, so compare that with 1 and done :-)

What are you using to play the sound files? Figure out what that needs and what your result from the earlier patch is and try to bridge the gap.
