Minim getLineIn feedback

Core Library Questions

i'm programming something that captures sound from the computer micro and creates some visual stuff with FFT and a beat detect.

The thing is that what is captured by the micro is played at the same time, creating some kind of feedback when volume is turned up.

the question is if it's possible to mute the sound but at the same time not to cut the getLineIn data flow, in the way that visuals continue working, but without any sound played.

thank you, i tried hard with my english ;)

Hej,it's quite a while ago, but I think, it will help people like me, who tried to find

a solution. You must simply mute the input in the setup:

Copy code

minim = new Minim(this);
audioInput = minim.getLineIn(Minim.STEREO, 1024);
audioInput.mute();

The Data is not lost and the input audio should not be played. I got the same

problem with FFT and SoundFlower. The AudioInput was doubled and so I got

a distorted feedback. Hope it works.

How about sketches like this one, which don't produce a feedback loop and don't use mute() ?
