I use scanrecorder, and often come back to 2 hours worth of audio. Rather than listening to 2 hours worth of audio to see if your company was dispatched, i wrote a matlab program to detect the fire tones in the wave file and report where in the file the tones where detected. also play 2mins of audio where the tone was detected.
i have it working in matlab right now. i am trying to write one for scilab which is free to download and can do alot of signal processing. future projects can be ctss decode and reading straight from the line-in and only recording when a company fire tone is detected.
email jrihl@yahoo.com and i will give the code for anyone to use.
download scilab at www.scilab.org or google scilab matlab you have to pay for, but is a standard for signal processing.
