virtual sound level meter

We have hosted the application virtual sound level meter in order to run this application in our online workstations with Wine or directly.

Quick description about virtual sound level meter:

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.

Features:

• MATLAB Based Software Sound Analyzer
• Mimics results of an ANSI Standard Integrating Sound Level Meter
• Includes Lp, LEQ, Octave and 1/3 Octave Band, NC, RC and FFT Analysis

Audience: Science/Research, Education, Engineering.

Programming Language: MATLAB.
