FreqAnalyst ~ Spectrum Analyzer VST

Posted by tom2tec on

Blue Cat’s FreqAnalyst is a free spectrum analyzer plug-in that lets you monitor the spectral content of your audio signal in real time.

This plug-in has been designed to provide extreme smoothness and high resolution for both time and frequency: unlike most spectrum analyzers, Blue Cat’s FreqAnalyst is able to display continuous variations even with a very high frequency resolution, thanks to its unique smooth interpolation algorithms.

Most aspects of the audio to frequency display conversion can be managed, which lets you total control over the monitoring. A special thresholding system has been developed to help you see the important parts of the spectrum easily. In case you need extra precision in a particular frequency range, you can zoom the display and check the part of the graph you are interested in.

The ABC Music Project ~ Plain Text Notation Format

Posted by tom2tec on

ABC, developed by Chris Walshaw, is a format designed to notate music using plain text. It was originally designed for folk tunes of Western European origin which can be written on one staff, but has since been extended to support the notation of complete, classical music scores.

Since its introduction at the end of 1991, ABC has become very popular. Programs on many operating systems use ABC as an input and/or output format. There are programs which produce printed sheet music or allow for computer performances, search in tune databases, or that analyze tunes in some way.

The aim of this project is to promote the ABC language by maintaining the ABC standard and a set of software and source code that manipulate and present music written in ABC.

ABC Tune Search

The abc tune search / tune finder gives you access to thousands of folk & traditional tunes from across the web.

VSLM ~ Virtual Sound Level Meter

Posted by tom2tec on

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

Posted by tom2tec on

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.

WaveShop ~ Windows Audio Editor

Posted by tom2tec on

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.

Humdrum Toolkit ~ Music Analysis & Research

Posted by tom2tec on

David Huron created Humdrum in the 1980s, and it has been used steadily for decades. Humdrum is a set of command-line tools that facilitates musical analysis, as well as a generalized syntax for representing sequential streams of data. Because it’s a set of command-line tools, it’s program-language agnostic. Many have employed Humdrum tools in larger scripts that use PERL, Ruby, Python, Bash, LISP, and C++.
