p5.AudioIn() does not work when build app using cordova. Therefore, I’ve used [cordova plugin](https://github.com/edimuj/app-audioinput-demo) to receive microphone audioContext. Now, I want to connect above context as input to p5.fft to visualize waveform.  
How can I achieve this?

Hi @sarthak_g ,  
welcome to the forum !  
I never used P5 embeeded in cordova, but I suppose you can use the [setInput()](https://p5js.org/reference/#/p5.FFT/setInput) function to set your audioContext as source.
