问题 I want to record sound (voice) using PortAudio (PyAudio) and output the corresponding sound wave on the screen. Hopeless as I am, I am unable to extract the frequency information from the audio stream so that I can draw it in Hz/time form. Here's an example code snippet that records and plays recorded audio for five seconds, in case it helps any: p = pyaudio.PyAudio() chunk = 1024 seconds = 5 stream = p.open(format=pyaudio.paInt16, channels=1, rate=44100, input=True, output=True) for i in

问题 In my Twilio-base application I create outgoing call via Twilio rest API. When target side responds, I put him to recently created conference.
