python - 如何在python 3上生成正弦波音调

我想使用1kHz频率的python 3生成正弦音调。我在stackoverflow (old question)上发现了一个老问题,但它使用的是python 2的pyaudio

我还有其他方法可以使用python 3吗?

尝试安装音阶时出错

最佳答案

tonescale installation instructions
建议使用pyaudio的python3版本:python3-pyaudio。

还有pygame

Windows的pyaudio install instructions建议
它提供了二进制车轮,因此应该平稳运行。
但是他们确实提到在异常情况下
可能需要PortAudio的编译。

您可能想尝试使用archive中的downrev轮。
