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. -- Thanks & Regards, Naveen Tamanam
