How to generate a Sine wave tone on python 3

Question

I am wanting to generate a sinusoidal tone using python 3 of 1kHz frequency. I found an old question on stackoverflow (old question) about it but that was using the pyaudio which is for python 2.

Is there any other way I can do this using python 3?

Answer 1

The tonescale installation instructions suggest using the python3 version of pyaudio: python3-pyaudio.

There is also pygame .

The pyaudio install instructions for Windows suggest that it should go smoothly, as binary wheels are provided. However they do mention that in unusual situations a compilation of PortAudio may be needed.

You might want to try using a downrev wheel from the archive .
