Description

This project is the MATLAB development of a virtual sound level meter. The program will read in a calibrated .wav file and allow the user to analyze it as one would analyze a sound field with a sound level meter. The software implements Fast, Slow, Impulse and LEQ; A, C and Flat Weighting; Ln and Noise Dose analysis; Octave and 1/3 Octave band analysis; high resolution FFT analysis and spectrograms. Band analysis can be made using fast FFT methods or slower, but ANSI standard methods.

Source code requires MATLAB + Signal Processing Toolbox.
Developed under MATLAB R2010a (but might work with some earlier versions)

Executable version does not require MATLAB and runs under Windows XP, Vista, and Windows 7.
