Python openAL 3D sound | 易学教程

问题

I just started with python and I am making program for audio manipulation. I am trying to implement 3D sound with openAL in my python application, but I just can get it to work

this is my code for 3D sound:

from openal.loaders import load_wav_file
from openal.audio import *

sink = SoundSink()   
listener = SoundListener()
SoundSink.activate(sink)
listener.position = (0, 0, 0)
listener.velocity = (0, 0, 0)
listener.orientation = (0, 0, -1, 0, 1, 0)
source = SoundSource()
wavsound = load_wav_file("test.wav")
source.queue(wavsound)
#SoundSink.play(source)
sink.play(source)

The code executes, but it doesn't play the sound

It turns out that there are some examples of how to use PyAL at the Bitbucket repository page here. Based off the audioplayer.py example, I made this annoying-sounding example with the sound alternative between the left and right headphone speaker according to a sine wave:

import time
import math
from openal.audio import SoundSink, SoundSource
from openal.loaders import load_wav_file

if __name__ == "__main__":
    sink = SoundSink()
    sink.activate()
    source = SoundSource(position=[0, 0, 0])
    source.looping = True
    data = load_wav_file("./sounds/Blip_Select.wav")
    source.queue(data)
    sink.play(source)
    t = 0
    while True:
        x_pos = 5*math.sin(math.radians(t))
        source.position = [x_pos, source.position[1], source.position[2]]
        sink.update()
        print("playing at %r" % source.position)
        time.sleep(0.1)
        t += 5
