Hey there,
I've been fooling around minim library to do some sound analysis.
What I want to achieve is performing FFT but do this for certain frequency ranges which are as follows;
20hz - 80hz = ........ Low Bass
80hz - 320hz = ...... Midbass
320hz - 1280hz = ... Midrange
1280hz - 5120hz = .. High Midrange/Low Treble
5120hz - 20840hz = . High Treble
For each range I need to get a magnitude so that I can send them to arduino.
Is this something possible to achieve.
Also I need to use the soundcard output of the computer as input data rather than using the built-in microphone with AudioInput function. However, couldn't find any way to do so. I reckon this is something feasible since I read the following comment lines under getLineIn function;
//it's feasible that the user may have the actual audio output of the computer as the active audio input
I do really appreciate if someone help me to sort those things.
Thank you.
