我正在英特尔爱迪生板上尝试 pyaudio,但它在内置测试中失败。在我的设置下单独录制和播放效果很好,但如果我尝试将输入连接到输出,则会出现错误。
文件“wire_full.py”,第 33 行,数据 = stream.read(CHUNK) 文件“/usr/lib/python2.7/site-packages/pyaudio.py”,第 605 行,读取返回 pa.read_stream(self ._stream, num_frames) IOError: [Errno 输入溢出] -9981
有谁明白有什么问题?
以下是在 pyaudio 中将输入连接到输出的示例代码:
"""
PyAudio Example: Make a wire between input and output (i.e., record a
few samples and play them back immediately).
This is the full duplex version.
