It doesn’t create smooth waveform transitions between each frequency step so you’ll hear pops whenever the frequency changes. Sometimes it can take a while before it starts playing. On Ubuntu: sudo apt-get install python-pyaudio Make sure you’ve installed pyaudio to make this run. This script generates a frequency sweep from 50 Hz to 10 kHz and is easily adjustable.
