Adobe Audition is great for decoding FTO's. I downloaded the 30 day evaluation version and liked it so much I bought the full version. I was able to get the Student Edition for $130.00, those Continuing Ed classes had an unexpected benefit!
Basically I record the FTO's using the most excellent Scanner Recorder program (free,
http://www.davee.com/scanrec/). I park the scanner on the fire frequency of interest and then allow it to record several sets of tones.
The file for a busy channel for a couple days is generally about 20 or 30 MB, depending on the amount of traffic and the quality settings, I tend to use "Radio Quality".
I then open the resultant .wav file in Audition. In the Waveform View window you will quickly learn how to "see" tone out sets by comparing the waveforms. In the Frequency Analysis window the actual tone freqs are shown.
Once set up it takes only a few minutes to analyze FTO's from a day or two's recordings . If you pay attention to the waveforms you can even discriminate different transmitters as they often have visible artifacts on the transmitters, such as unique squelch tales.
When I first got into FTO's after the 396 came out I decoded hundreds of sets of tone-outs in a period of weeks on a dozen different freqs in my area. I found that the BC780/785/796 scanners record jack is a great source of the audio but that the speaker jack works even better. I set the volume of the scanner to fill the wave form window in Scanner Recorder to an optimum level so that the wave of tones are just slightly less than filling the window and then use the computers speakers to listen to the audio. When I leave or go to bed for the night I just turn off the speaker or turn the computer volume down and leave the computer and scanner on to record audio overnight or while I am away from home.
I once had this set up on my local fire channel and went on a week's vacation and when I came home the computer had a 3 GB wav file. It took me less than an hour to go thru the entire file, cut and paste the various tone sets into separate .wav files and analyze the results. Remember to include the voice message with the tone set so you can identify the use of the tones.
