Python openAL 3D声音 [英] Python openAL 3D sound

问题描述

我刚开始使用python，正在制作音频处理程序。
我试图在我的python应用程序中使用openAL来实现3D声音，但我只能使其工作

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

这是我的3D声音代码：

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)

代码已执行，但没有播放声音

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

推荐答案

事实证明，其中有些在Bitbucket存储库页面上如何使用PyAL的示例此处。基于 audioplayer.py 示例，我制作了这个令人讨厌的示例，根据正弦波在左右耳机扬声器之间进行了声音选择：

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
