This short script continuously reads sound data from the windows soundcard (microphone of line-in) and displays the updated frequency spectrum. It is mostly, a data acquisition example using the built-in Windows sound card.
Hi, does it work under linux/mac os x?
Can u tell me how to find the frequency spectrun of the recorded speech signal.
After the plotting command. This allows for continuous update.
Albert Lu, try setting duration = .2 in the script.
It would be nice if the plot is updated constantly
