pyaudio

I'm currently developping a VOIP tool in python working as a client-server. My problem is that i'm currently sending the Pyaudio input stream as follows even when there is no sound (well, when nobody talks or there is no noise, data is sent as well) : CHUNK = 1024 p = pyaudio.PyAudio() stream = p.open(format = pyaudio.paInt16, channels = 1, rate = 44100, input = True, frames_per_buffer = CHUNK) while 1: self.conn.sendVoice(stream.read(CHUNK)) I would like to check volume to get something like this : data = stream.read(CHUNK) if data.volume > 20%: self.conn.sendVoice(data) This way I could

I am having an issue with my code which causes a memory error. I believe it is caused by this function (see below). def sendAudio(): p = pyaudio.PyAudio() stream = p.open(format = FORMAT, channels = CHANNELS, rate = RATE, input = True, output = True, frames_per_buffer = chunk) data = stream.read(chunk) client(chr(CMD_AUDIO), encrypt_my_audio_message(data)) def keypress(event): if event.keysym == 'Escape': root.destroy() if event.keysym == 'Control_L': #print("Sending Data...") sendAudio() #print("Data Sent!") What the function does is read from the microphone then send that data over the

I'd like to tell you what I've tried and then I'd really welcome any comments you can provide on how I can get PortAudio and PyAudio setup correctly! I've tried installing the stable and svn releases of PortAudio from their website for my Core 2 Duo MacBook Pro running Snow Leopard. The stable release has a sizeof error that can be fixed(?) , but the daily svn release installs fine with ./configure && make && make install (so this is what I'm using). The tests are compiled properly and I can get the binaries to produce output/can read microphone input. Ok, so then PyAudio has troubles.

Good day, I'm trying to record my speaker output with Python using PyAudio. Currently, I'm able to record my microphone input and send this over to the 'listener'. What I'm trying to do now is create a loopback, so it will record the output from my speakers. I was able to do this with the 'Stereo Mix' from windows, but since this needs to be cross platform, there should be another way to do this. Does anyone has some advice on how I could achieve this? Here is my current code for recording an input stream. import socket import pyaudio import wave #record CHUNK = 1024 FORMAT = pyaudio.paInt16

I'm trying to grab samples from a stream of audio and put them in a shared Queue. I have another process that pulls from this queue. When I run, I get this error: * recording Traceback (most recent call last): File "record.py", line 43, in <module> data = stream.read(CHUNK) File "/Library/Python/2.7/site-packages/pyaudio.py", line 605, in read return pa.read_stream(self._stream, num_frames) IOError: [Errno Input overflowed] -9981 EDIT: Apparently problem has been around for a while with no solution posted (I tried their suggestions): PyAudio Input Overflowed -9981 - No solution working Geting

I use Python 2.7.3, Mac OS 10.8.2 and Xcode 4.5.1 I am trying to record sound using PyAudio following the instructions in http://people.csail.mit.edu/hubert/pyaudio/ and using the program """PyAudio example: Record a few seconds of audio and save to a WAVE file.""" import pyaudio import wave CHUNK = 1024 FORMAT = pyaudio.paInt16 CHANNELS = 2 RATE = 44100 RECORD_SECONDS = 5 WAVE_OUTPUT_FILENAME = "output.wav" p = pyaudio.PyAudio() stream = p.open(format=FORMAT, channels=CHANNELS, rate=RATE, input=True, frames_per_buffer=CHUNK) print("* recording") frames = [] for i in range(0, int(RATE / CHUNK
