New TwoToneDetect in the works - Python based

[gfdfortynine]

Andy
I'm a having a problem with false pages with V57. It started when I added a second dept to the config.
It triggers the original department "1" when the tones to the new departments "2" are put out.
I have raised the B tone length to 3 from 2 and had added debounce of 2 on dept 1
Alert was not sent to department 2. I have rarely had falsing in the past (used V52) but has happend 3 times in the last couple days. (man these guys have no sense of humour at 3am )
I am using the left channel to feed this software and my right channel (another scanner) is supplying a live feed so maybe it has something to do with that.
I have tried to replicate this on a second computer but it works correctly on it ie. alerts go to department 2
Dept 1 tones are Atone = 1472.9 and Btone = 1513.5
The new stations tones are Atone = 510 and Btone = 365. Also this incident was a stacked page
the other stations tones are Atone = 584 and Btone = 553

Attached is the debug file but only shows really that there were tones recieved.

Is it possible to add some addititional filtering to the Atone? Seems the software is always sitting there with the Atone triggered waiting for Btone while there is voice traffic on the channel.

Also this morning dept 1 had a call and all that happened was the text with no audio was sent no emails. Sorry no debug file for that but might have been the index error.


Great software Andy and Thanks.

Have you had the left/right setup running in the past without falsing?

Also, make sure that when you added the second tone set to the tones.cfg file you used a new tone number for the heading i.e. [Tone1] for the original and [Tone2] for the new one. Using [Tone1] for both is a common copy/paste error and would cause issues. Using the Editor should do this automatically but double check it.

The no audio emails being sent is very likely the index issue with v57.

I have had the left right set up working without issue from the begging. The priority channel on the live feed is the same as the paging scanners channel. BTW I have just gave ttd is own audio input (had an extra usb for the live feed) every once in a while I would get audio from the live feed mixed in so it had to be done

To late to check the duplicate Tone1 I deleted department 2 from the system (is still in testing phase) but I did use the config software to set it up. The second computer does show Tone2.
I will download v58 and reconfig the second department and let you know the results.

Thanks

Ok a few things come to mind. First, the program right now gets the audio input in mono mode. When I've done testing here, the audio gets mashed together from both left/right into a single channel. When you had the left/right setup in the past, did audio from the live feed scanner cause the program to start looking for tones (i.e. something other than "No Audio" on the main screen)? If not, I'm surprised.

Since your live feed had the same channel as a priority channel you probably wouldn't notice it most of the time since both left/right would be hearing the same thing.

Second, if I understand you correctly, the program was saying it detected Dept 1 when Dept 2 was actually paged? That I don't understand...the tones are far enough away from each other that they shouldn't have issues. The only thing I can think of is that if there was also other radio traffic on the live feed channel that was interfering, that might cause it, but I wouldn't think it would be that consistent to do it three times in a row.

This is a strange case...did anything else change, either when you went to v57 or when you added the second department?

yes it sent the page recieved to dept 1 with department 2 tones, Dept 2 received nothing.
When the feed scanner was receiving I never seen anything in the ttd window unless of course it was the same channel and the traffic was close. The feed scanner is hooked to a big antenna and the pager scanner just uses the on board one.

The only thing that I changed was I lowered the squelch on the pager scanner a bit and raised its on board antenna 6". I wasn't getting dept. 2 pages for some reason ie no display in ttd window, so I was attempting to rectify that. So fixing that created this LOL

I tried V58 on test computer and works fine on dept 1 but will not pick up ToneB dept for dept 2 which is 365. The ttd window is displaying between 1000 and 2000. Shows fine on V52 and V57 with same audio track

[aaknitt]

For those having trouble with v57 detecting tones but not sending emails (i.e. the "index error"), please try v57a, which I just posted to the Previous Releases page

I only posted the EXE file, not the whole ZIP directory, just copy that file into your existing v57 directory. Let me know if that resolves the issue or not.

As for v58, the more detailed feedback the better. I know a few people seem to have it running ok, anyone else, good or bad?

Thanks,

Andy

On your second computer that you're getting Department 2 ok on, are you also detecting Department 1 on that computer? If you're able to reproduce this somehow and send me recordings of whatever you've got that would help...if I can reproduce it here, we can fix it. If it can't be reproduced, that's going to be hard to figure out.

Hi Andy,
I'm currently testing V58 and all seems fine so far. Just 1 dept. with 1 set of tones. Using Win7 with a Minitor IV as the receiver. Thanks for a superb product!

yes dept 1 was working. I was using the live audio archives to try and simulate the problem (had my playbook feeding my computer) The file's to big to upload here.

See my previous post it has a recording from dept 2 which worked and some findings on V58

I'm getting 510 Hz and 365 Hz on v57 and v58 with the file you posted. Any chance you're using a microphone for this testing? If so, it could be an issue with the frequency response of the speaker/microphone combination. Small speakers have poor low frequency response, which may cause a higher frequency in the spectrum to dominate. There is a definite 1500 Hz hum on all of the audio in the left channel of that audio, if you're using a mic with small speakers you might pick that up instead of the 365 Hz component.

Was using patch cord head phone to mic in for test.
v52 and v57 with that track work with same hook up.

Hello,
I was curious as to why when I make a tone in audacity and play it through my computer it does not pick up the correct frequency. In audacity I go to generate and click on tone. For waveform I use Sine, frequency: 296.5 hz and amplitude of 0.8 it shows in two tone detect as 891.0 HZ.

If someone could help it would be greatly appreciated

How are you feeding the tone from Audacity into TwoToneDetect, and which version of TwoToneDetect are you using?

Try taking that tone set out of the tones.cfg file and then play the tone set...let me know if you get the correct frequency for the A and B tones as it's playing on the main screen of the program.

Also, what Btonelength and Btonedebounce are you using in your tones.cfg file?

I am using a double ended stereo cable. I was using the latest version 58 but downloaded 57 and 57 detects all tones accurately with 2hz

I am using a double male speaker cable to run the tones from audacity back into my computer.

I was using version 58 which was giving me the false tone readouts. However, I downloaded version 57 and it picked up the tones within a 2hz difference from the tone.

I removed the 510 and 365 tones from tones config.. no difference in frequency readout with V58 still ok V57

I am using a 3 sec Btone length with a 4 debounce for Dept 1 and 3 sec no debounce for Dept 2

BTW V57a up all day 2 calls no falsing. The county did a bunch of paging today and some of them were the stacked combo that seemed to be the culprit.
I'm gonna add Dept 2 again to see how it goes. I have changed the debounce from 2 to 4 and ttd has its own audio input channel since the falsing, so its worth trying IMHO.

For those having trouble with v58 being off-frequency, is this repeatable? I'm having trouble reproducing it here, it's reading the same as v57 and prior for me on a few different setups.

Andy

Thanks Andy. v57(a) is working fine now with the fix. Going to revisit v58 and do some more testing. Can't be specific as to the problems. It kept displaying a bunch of lines and would fill the page and the IndexError, at that point I went back to v57. I am really looking for v59 with stereo left or right selection option. :-)

Anytime I attempt a lower tone it picks it up at a higher tone frequency ranging anywhere from 550-2550 hz, I will attempt to record a video of this happening
