Oct 26, 2014 · I'm trying to record the output from my computer speakers with PyAudio. I tried to modify the code example given in the PyAudio documentation, but it doesn't work.
Mar 13, 2016 · stream_play.close() play.terminate() "RATE" is the number of samples collected per second. "CHUNK" is the number of frames in the buffer. Each frame will have 2 samples as "CHANNELS=2". Size of each sample is 2 bytes, calculated using the function: pyaudio.get_sample_size(pyaudio.paInt16). Therefore size of each frame is 4 bytes.

Nov 28, 2011 · ivan-onys gave an excellent answer, but there is a little addition to it: this script will produce 4 times shorter sound than expected because Pyaudio write method needs string data of float32, but when you pass numpy array to this method, it converts whole array as entity to a string, therefore you have to convert data in numpy array to the byte sequence yourself like this:
Jul 28, 2015 · All examples I found using PyAudio rely on writing the NumPy array to a WAV file first, but I'd like to have a preview function that just spits out the NumPy array to the audio output. Should be cross-platform, too. I'm using Python 3 (Anaconda distribution).
