Default Audio processing from line-in using Linux

If there are any Linux users here, do any of you pipe your receiver
into the line in jack of your sound card and process it using software
in Linux? I am trying to avoid days of searching and work if there
might already be a method in use by someone else.

Thanks,

What type of processing do you have in mind?

I was thinking of doing various filtering for noise etc. in real time.

Hi,

I use linux and there's lotsa new stuff out at Sourceforge and
Freshmeat.net.

Do a Google from http://www.google.ca/linux (or .com)

I use Audacity myself for treating recorded .wav files.

Some of these programs have a modular setup. You can 'wire them' using
the blocks you want.

Some misc. radio software

http://software.freshmeat.net/browse...rby=&offset=40

nine or ten Linux software links at the bottom of this page. Some ham
decoding software using the sound card input.

http://www.g3vfp.org/download.html

============================================
Check out MULTIMON, too.
http://www.google.ca/search?hl=en&ie...G=Search&meta=

The multimon software can decode a variety of digital transmission modes
commonly found on UHF radio.

A standard PC soundcard is used to acquire the signal from a
transceiver. The decoding is done completely in software.

Currently, the following modes are supported: AX.25: 1200 Baud AFSK,
2400 Baud AFSK (2 variants), 4800 Baud HAPN, 9600 Baud FSK (G3RUH),
POCSAG: 512 Baud, 1200 Baud, 2400 Baud and Miscellaneous: DTMF and ZVEI.
=============================================

Good luck
