Hi Michael, I am trying to detect the tone on IVR.That tone occurs at one point of time before IVR navigates further. On Wed, Jun 10, 2015 at 1:42 AM, Michael Jerris <mike@jerris.com> wrote:
It sounds like a ring tone, if thats the case, you should probably work off the specs for that tone instead of the recording which might have other artifacts in it. What exactly is the full scenario where you need to detect an inband ringback tone?

Hi Nandy,
I am glad to see your reply. I am trying to detect the tone which sounds like a simple ring. and I can't guess when that could occur, so I listen for the tone through out the call. I am attaching the tone.

Hi,
What are you trying to do with tone_detect? Is it call progress? Fax detect?

Hi,
I am using following command for tone detection,
tone_detect <uuid> <key> <tone_spec> [<flags> <timeout> <app> <args>] <hits>
Many times I end with the false detection. In my case I haven't given all optional args. I just gave tone_detect uuid key tone_specs. It would be something like,
tone_detect 8582g3b8-f7db-10e4-2ac4-c01885c1ffd3 tone_name frp1,frp2,frp3
Where frp1, frp2 and frp3 are the frequencies of few peak amplitudes of the tone. Those frequencies are detected through audacity by plotting spectrum, Spectrum specs are, Alogorithm: Spectrum, Fuction: Hanning window or Bartlett window Size: 512 Axis: Log Frequencies
Is there anything I am missing. Any suggestions are highly appreciated, Thanks.
