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.
- 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
UN GRAN PROYECTO QUE TIENE GRANDES POSIBILIDADES TANTO EN DOCENCIA COMO EN FUTUROS DESARROLLOS EN EL CAMPO DE LA ACÚSTICA DE SALAS, ANÁLISIS DE LA RESPUESTA IMPULSIVA, ETC...
Really simple, and useful use it for my voice recordings so i can know that i didn't talk too loud!
Great project! I recommend this program strongly!
