Sound Card Spectral Analysis

01 Jul 2008 (Updated 09 Jul 2008)

Acquire data from soundcard and plot in time and frequency domains

File Information
Description	Acquires buffers of data from the system default sound card, calculates the power spectrum of the data and plots this along with the raw sampled data to screen. Useful as a quick and dirty (and completely uncalibrated) audio frequency spectrum analyser. See http://iheartmatlab.blogspot.com for further details.
Acknowledgements	This submission has inspired the following: Sound Card Spectral Analyser GUI
MATLAB release	MATLAB 7.0.4 (R14SP2)
Other requirements	Windows platforms only (constrained by 'audiorecorder')
