Hello,
I'd like to be able to analyze incoming audio from a sound card using
Python, and I'm trying to establish a correct architecture for this.
Getting the audio is OK (using PyAudio), as well as the calculations
needed, so won't be discussing those, but the general idea of being able
at (roughly) the same time: getting audio, and performing calculation on
it, while not loosing any incoming audio.
I also make the assumption that my calculations on audio will be done
faster than the time I need to get the audio itself, so that the
application would be almost real time.
So far my idea (which works according to the small tests I did) consist
of using a Queue object as a buffer for the incoming audio and two
threads, one to feed the queue, the other to consume it.
The queue could store the audio as a collection of numpy array of x samples.
The first thread work would be to put() into the queue new chunks of
audio as they are received from the audio card, while the second would
get() from the queue chunks and perform the necessary calculations on them.
Am I in the right direction, or is there a better general idea?
Thanks!
