The audiodev Module

(Unix only) The audiodev module provides sound playing support for Sun and SGI computers. Example 9-8 demonstrates this module.

Example 9-8. Using the audiodev Module

File: audiodev-example-1.py

import audiodev
import aifc

sound = aifc.open("samples/sample.aiff", "r")

player = audiodev.AudioDev()

player.setoutrate(sound.getframerate())
player.setsampwidth(sound.getsampwidth())
player.setnchannels(sound.getnchannels())

bytes_per_frame = sound.getsampwidth() * sound.getnchannels()
bytes_per_second = sound.getframerate() * bytes_per_frame

while 1:
 data = sound.readframes(bytes_per_second)
 if not data:
 break
 player.writeframes(data)

player.wait()
