audio input in max


    Apr 18 2006 | 10:26 pm
    Hello, I am trying to create a very simple patch in which when someone talks in to a microphone it triggers a video to play. However the way the patch is working right now is that the signal has to be constant for the video to be playing, but I just need the participant to say one word and the video to start. What should I use as the audio input in max to do this, I have no clue. Does anyone out there know? Thanks! Jen

      you can just connect adc~ to a peakamp~ object setted on a volume threshold and that's it: you'll get an amplitude change due to the spoken word into the microphone. What do you mean with " the signal has to be constant"?

      Are you sure this works? How could you make peakamp~ work without audio being switched on? (I am sure it doesn't ;-)
      Jen, follow the logic, you need a bang, or a 1 to start the movie, once its started, you don't want it to trigger anymore, and you don't want it to stop. You didn't paste a patch into your mail, so I guess you translate the level of audio directly to control on/off of the movie - put a [select 1] behind that... and the other 1001 possibilties to solve such problems will be easy to find after you went through all the tutorials....

      i guess that if the audio is always on as the mic is plugged in, then you put a threshhold level that is higher than noise/rumors level but lower than the spoken word volume.
      this is not the best solution but it might be the max objects' area where you need to point to and search a bit.
      just that :-)
