To: "pjsip list" <pjsip at lists.pjsip.org> Date: Wednesday, 16 November, 2011, 5:40 AM Hi Vikas, The tonegen generates sin wave of both specified freqs, in get_frame(), the sum of all amplitudes is returned. Don't know the signal processing term. If your need other alternative, just implement it using pjmedia port framework, so your app can use it in the same way as tonegen or any other pjmedia ports.
