Read the file that has been saved [x,Fs] = audioread('voice.wav') Add Gaussian noise to the voice signal y = awgn(x,10,'measured') Save the noisy voice filename = 'noisyvoice.wav' audiowrite(filename, y, Fs) Plot the noisy signal along with the original signal and analyzing both.
PWM signal very noisy at high frequencies - Audio ...
https://forum.arduino.cc/t/pwm-signal-very-noisy-at-high-frequencies/957224
Hi all, I'm using the tone() function at the moment to generate a PWM signal that drives a small speaker directly from my Arduino Nano 33 BLE digital pin. At lower frequencies (c. <8000Hz), the tone comes out fine as a fairly clean sound, but as it goes up in frequency, around 15-20kHz, the sound becomes very noisy and doesn't make a clear pitch. Looking at the signal …
