File Information

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.

Extends previous function ( into a Matlab Class.

The GUI uses an instance of this class.

See for a detailed run-through of the code and the programming techniques utilised.


Sound Card Spectral Analysis inspired this file.

MATLAB release MATLAB 7.0.4 (R14SP2)
Other requirements Windows platforms only (I assume - not tested under *nix platforms)
