Noice Cancelling

Hello. Is it possible to create a anti-noise from a recorded sound with this library?
e.g.: record a sound by microphone. process the Phase-shifting and play it through the speakers?
thx. mb1701

Hi there,
I'm not exactly sure what you are trying to achieve. You will not likely be able to remove noise very effectively by phase-shifting. That works better for hum removal. A filter is probably what you need.

thx for your reply. what I want to achieve is to eliminate sounds in an office environment by headphones attached to the PC-Out. So I want record the incoming sounds (by microphone) and create REALTIME the phase-shifted anti-noise to the headphones. what I learned from the noise-cancelling headphones, they only reduce the lower-frequencies. so I thought maybe I could use the library to success :-)
