File Information

The file is written for MATLAB 6.5 it aquires data from the sound card . Fourier spectral power analysis one second of audio signal sample is analyzed by simply running the M-file. The frequency contents of the voice analyzed are shown of a plot. I have used this program to compare voice qualities of many music starssome proved realy as good as they claim others didn't. the property to look for on the plot is the number of peeks, the frequency spacing between peeks, their relative amplitude ratios. for good sopanos higher frequency contents has to large

MATLAB release MATLAB 6.5 (R13)
Other requirements none

This audio analyser is a nice coded file that works as a good starting point for spectral analysis of voice.
