this is my first post. I want to create a .wav file from an array of amplitude and frequencies. How can I do this ? Thank you I am able to get the spectrum too.

  • "Amplitude and frequencies": do you mean that what you have is a the result of an FFT transform ? Can you tell us how was this array generated ? – Gabriel Devillers Dec 19 '18 at 17:45
  • that's it, and i've made some transformations on my signal, so i have one array containing amplitude and one list containing frequencies. – nvoul Dec 19 '18 at 18:00

Use the write function to create a wav file. Make sure that the array is in integers as well.

  • Ok but what should my array contain ? The amplitude of the signal ? – nvoul Dec 19 '18 at 17:58
