[Sndobj-devel] Recording Sound w/ pysndobj

[Nikolas F. <cor...@gm...>]

Hello,

I'm a two week old newbie to OOP and python, but I have lots of Matlab
experience from my research. I found psysndobj a few days ago, and it
looks promising for my current foray into python audio. My long-term
goals using pysndobj are:

(1) buffer audio streaming in from a microphone
(2) plot the spectrum of the audio stored in the buffer
(3) give the user an option to select a band of frequencies from the
display, in order to band-pass filter subsequent audio buffers around
the chosen frequency-band
(3) update the buffer and spectrum display every second or so

I gather that pysndobj can do the recording, buffering and filtering,
and I was thinking of pyQT for the GUI.  I'm currently far, FAR away
from those goals.  Currently, I only understand how to monitor my mic:

###Start Code

import sndobj
import time

#Create input and output objects
input = sndobj.SndRTIO(1, sndobj.SND_INPUT)
output = sndobj.SndRTIO(1, sndobj.SND_OUTPUT)

#Setup input object
mic = sndobj.SndIn(input)

#Set output
output.SetOutput(1, mic)

#threading
thread = sndobj.SndThread()
thread.AddObj(input, sndobj.SNDIO_IN)
thread.AddObj(output, sndobj.SNDIO_OUT)
thread.AddObj(mic)

#start processing
thread.ProcOn()
time.sleep(30)
thread.ProcOff()

###End Code

Does anyone have any **simple** examples of how to use SndBuffer in
pysndobj? Comments/other recommendations on using pyQT for displaying
and interacting with the spectrum? I realize that this is a high-level
inqury, but I'm floundering a bit with coding, since its a bit
difficult to find relevant examples online, which is how I learned a
lot in Matlab (by editing other people's code to my purpose).

Thanks!
