调用play函数来播放声音,需要传入需要播放声音的波形,和采样率。 import sounddevice as sd sd.play(myarray, fs) 查看声音设备 计算机上可能有多个声音播放/录制设备,sounddevice会默认使用系统默认的设备。调用query_devices()函数会显示系统所有的声音设备。 sd.query_devices() 下面是我计算机上的声音设备,>标示为...

AudioArrayClip类是AudioClip的直接子类,用于从一个numpy音频数组构建音频剪辑。AudioArrayClip类只有一个构造方法,在构造方法内定义了一个内嵌函数make_frame,该make_frame函数作为AudioArrayClip构建音频帧的方法。 1、构造方法调用语法: __init__(self, array, fps) ...

To play a sound in Python, you’ll need to install a separate library. Note: Although the wave module itself doesn’t support audio playback, you can still listen to your WAV files as you work through this tutorial. Use the media player that came with your operating system or any third...
