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

Musicalgorithms ~ Create Your Own Music
Algorithms and Interactive Tools for Exploring Music Composition, Analysis, and Interdisciplinary Learning.
This web site has interactive tools that provide a unique learning experience for users, regardless of their musical training. Students of music composition can explore algorithmic composition, while others can create musical representations of models for the purpose of aural interpretation and analysis. Here, the algorithmic process is used in a creative context so that users can convert sequences of numbers into sounds.
Spek ~ Acoustic Spectrum Analyzer
Spek (IPA: /spɛk/, ‘bacon’ in Dutch) helps to analyse your audio files by showing their spectrogram. Spek is free software available for Unix, Windows and Mac OS X.

TiMidity++ ~ Synthesizer & Player
TiMidity++ is a software synthesizer. It can play MIDI files by converting them into PCM waveform data; give it a MIDI data along with digital instrument data files, then it synthesizes them in real-time, and plays. It can not only play sounds, but also can save the generated waveforms into hard disks as various audio file formats.
TiMidity++ is a free software, distributed under the terms of GNU general public license.
Features:
- Plays MIDI files without any external MIDI instruments at all
- Understands SMF, MOD, RCP/R36/G18/G36, MFI
- Converts MIDI files into various audio file formats: .wav, .au, .aiff, .ogg and so on
- Uses Gravis Ultrasound compatible patch files and/or SoundFonts as the voice data
- Displays information about the music that is now playing
- Various user interfaces: ncurses, gtk, Win32-GUI, and others
- Plays remote MIDI files over the network
- Plays MIDI files in archive files
- Displays sound spectrogram for the playing music
- Trace playing
WaveShop ~ Windows Audio Editor
WaveShop is a free, open-source audio editor for Windows XP/Vista/7/8 32-bit and 64-bit. WaveShop is fast, lightweight, and bit-perfect, meaning samples aren’t altered unless they need to be. Editing a portion of an audio file only affects that portion; the rest of the file is untouched. Blocks of audio can be cut and pasted without changing their contents at all. This is especially useful for patching a finished master without corrupting its dither. Waveshop’s features include peak, RMS and spectral analysis, normalizing, fading, sample rate conversion, audio generation, plug-ins, and more, all with unlimited undo and comprehensive help.
