I would think a fan might make a regular noise (motor, air buffeting), not to mention that putting a microphone directly into an air path can wreck it. A simple solution might be to connect to an analogue tv tuner or radio tuner off-station, to get the (almost) white noise from it. -- [tim@localhost ~]$ uname -r 2.6.27.25-78.2.56.fc9.i686 Don't send private replies to my address, the mailbox is ignored.
