Re: Little OT : Software for Active Noise Cancelling or Reduction

[Mirco Piccin <pictux@gmail.com>]

Hi, 
i find this thread:
http://forum.audacityteam.org/viewtopic.php?f=28&t=442

It's quite old, but it could be a start point.

The aim is to create an anti-phase in realtime.
This job is done by a don't-know small (and suppose poor) chip into some headphones that provide noise cancelling/reduction.
So i suppose it's not so difficult to do the same using a pc process and Debian (or other linux distro, of course).

Of course i don't want absolute noise cancelling (i think that it's also impossible).
A good reduction is enough.

Regards
M

Is it technically not feasable, meaning that a room is too large to do noise
cancelling in, or not feasable from the linux software prespective?
