maximum~ problem

Aug 29 2012 | 2:32 am

Hi there, can you help me figure out why the maximum~ object doesn’t pass the ‘greater’ signal clean?
I am learning max and would like to contruct an instrument that differentiates the two incoming sound signals and pick the one with the greatest amplitude. Thank you!

I fixed the mis-connection on the patch I posted, but it still does not pass the greater signal clean.

Maximum~ doesn’t do what you think it does. It’s like a dynamic greater than less than. If one inlet sees a one and the other a zero, it passes the one. Audio signals jump all over the place.

What you want is a ducker/gate kind of thing. You need to analyze the volume of each signal (maybe using [peakamp]) and go from there.

Thank you! I will go back to the drawing board and use the if then object (as attached) and analyze the signal dB and go from there. Thanks a lot!

I still don’t understand where the Maximum~ object would be utilized. I thought it was differentiating signals based on amplitude. There is a maximum for max that is very clear, but the msp one, I don’t understand. If anybody can clarify further, I will appreciate it.

You use it the same way as the max one, doing math comparisons, but at audio rate. Not really for actual audio.
