Hi Jeff,

I Don't know how much use this is to you, but referring to the sub-aural frequencies (beating) heard when two notes are almost in tune.

a beat frequency isolator patch...

The beating between two notes can be isolated and used to control some other parameter,e.g. noise, or the amplitude of another sound, or after scaling, something else.

Should work with Pd-extended Ed

Hi, can someone please enlighten me re: what I am calling real time DSP. How possible would it be to create following scenario.

1. create real world acoustic sound (e.g. piano note)
2. mike that sound
3. monitor sound over headphones
4. analyze and process according to analysis in real time (immediate).

for example play note isolate per instructions an upper partial/harmonic in that note and equalize (or whatever you would call it) to have just that partial be heard. So that in real time you are hearing just that harmonic.

Thanks in advance if anyone is willing to answer this.
