Entering equations in max

January 22, 2006 | 4:39 pm

Hi all

I am aiming to use max/msp as the interface for a listening test I will run next month. Essentialy I want to make a program which automatically selects one of 2 algorithms and mathmatically processes an audio file according to the selected algorithm then outputs the signals to the relevant speakers. Is this sort of thing possinble in max/msp. Any help greatly appreciated.

Thanks
Ian

Absolutely. If the processing can be done live, you could route
output from sfplay~ left or right using "gate~ 2" in order to apply
one or the other processing. Objects like poly~, mute~ and/or pass~
might be useful to avoid processing taking place in the algorithm
that is not currently used.

If the processes are to heavy to do in real time, you could look into
mxj in order to do processing on the content of a buffer~. Check out
the documentation and java code for "mxj~ buf.Op".

If the sound to be processed is the same all the time, and the two
processes are also constant, the simplest solution would be to
prepare the sound files beforehand, and decide on the fly which one
to play.

Best,
Trond
