micro.py

micro.py is a tiny python module that captures microphone input and makes the raw data available by a read function. It makes use of python-gstreamer.

Legal

I grant anyone the right to use this work for any purpose, without any conditions, unless such conditions are required by law. There is no warranty.

Example usage

example.py records one second, unpacks the data and prints the values


#!/usr/bin/env python

import micro, time, struct

start=time.time()

micro.record()

while time.time()<start+1.0:
	data = micro.read(1000,1)

	for i in struct.unpack( '500h' , data):
		print i

micro.stop()

micro.loop.quit()

Reference

record(): Starts recording
stop(): Stops recording
read(n=-1, timeout=False): Reads n bytes. If n n is negative or non-existent, read whole buffer. You can also specify a timeout.
loop: The gobject.MainLoop() that is required for using gstreamer. As the mainloop is running in a separate thread, you need to stop this thread by executing loop.quit() in order to make your program terminate - otherwise it will wait for this thread forever.
