Python：将传感器数据转换为连续的调频音频

Question

I have a piece of python script that runs through a continuous loop (~5Hz) to obtain data from a set of sensors connected to my PC, much like a proximity sensor.

I would like to translate this sensor data into audio output, using python and in a continuous manner. That is: whilst my sensor loop is running I want to generate and play a continuous sinusoidal audio sound, of which the frequency is modulated by the sensor output (eg higher sensor value = higher frequency). This is sort of the output that I want (without the GUI, of course: http://www.szynalski.com/tone-generator/ )

I've looked through a lot of the available packages (pyDub, pyAudio, Winsound)but all seem to solve a piece of the puzzle, either signal generation, saving or playing, but I can't seem to find out how to combine them.

• It's possible to perform frequency modulation and link different frequencies together and then save them, how to play them in real-time and without clogging up my sensor
• It's possible to play threaded audio using WinSound -> but how to update frequence in real-time?

Or is this not a feasible route to walk on using python and should I write a script that inputs the sensor data into another more audio-friendly language?

Thanks.

Does it not work if you just add winsound.Beep(frequency_to_play, 1) in the loop?
