Vslm_0_4_1.m requires the signal processing toolbox. Users should then run vslm_0_4_1.m to run vslm. Vslm_0_4_1_docs.zip and unzip both to the same directory. Matlab users should download the vslm_0_4_1_matlab_source.zip and The archive also includes vslm_0_4_1.fig and vslm_0_4_1.m which are the MATLAB source files MATLAB USERS Vslm.hnd is the HelpNDoc file which is the source file for all the documentation formats Vslm.pdf which is a PDF version of the same documentation Vslm.htm and the /files subdirectory which contains an html format help file The documentation includes vslm.chm, a windows helpfile format help file This is actually a wrapper program that runs the true executable, matgui, and shows asplash screen while the MATLAB runtime library loads (this can take a while). To start vslm run the vslm.exe executable. This will extract the contents into the directory and install the MATLAB runtime library if necessary Move the vslm_0_4_1_pkg.exe file to the directory where you want the vslm executable to be installed (create the directory if necessary) and run the file. This file includes the windows executables, help files, and MATLAB runtime libraries. Windows users without MATLAB and the signal processing toolbox installed should download the vslm_0_4_1_pkg.exe. Main GitHub Project Site: WINDOWS EXECUTABLE USERS: You can download VSLM executables and latest stable release from the GitHub release page and get the most up-to-date development version from the main GitHub Project site. It has been developed for the analysis of calibrated digital recordings. This software does not do real-time sound level measurement. Source code requires MATLAB + Signal Processing Toolbox.ĭeveloped under MATLAB R2010a (but might work with some earlier versions)Įxecutable version does not require MATLAB and runs under Windows XP, Vista, and Windows 7. Band analysis can be made using fast FFT methods or slower, but ANSI standard methods. 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. wav file and allow the user to analyze it as one would analyze a sound field with a sound level meter. This project is the MATLAB development of a virtual sound level meter.
