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, -Al A. -- remove NUNYA to email me ~/.signature |

What type of processing do you have in mind?

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

Do a Google from http://www.google.ca/linux (or .com) I use Audacity myself for treating recorded .wav files. -- Gregg *It's probably useful, even if it can't be SPICE'd* http://geek.scorpiorising.ca |

You can 'wire them' using the blocks you want. http://www.opensound.com/ossapps.html http://alsamodular.sourceforge.net/ http://linux.omnipotent.net/article....ticle_id=10916 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 |
