Audio Signals

using this code user can actually feel the effect of filtering on audio signals and also see how filtering varies with changing the filter used Platforms: Matlab

These routines scramble an audio file by moving around short, overlapping windows within a local window. They can be used to create new versions of existing recordings that preserve the spectral content over longer time scales, but remove structure at shorter timescales. This can be useful e.g....

Marsyas, which stands for Music Analysis, Retrieval and Synthesis for Audio Signals is specially designed to be an Open Source software framework for audio processing. The main goal of the framework is to provide a general, extensible and flexible architecture that allows easy experimentation... Platforms: Windows

This application lets you view audio signals in a frequency display. It uses an FFT algorithm to convert the time signal to the frequency signal. There are several options to customize the display, i.e. zoom, scale etc.The application is intended to be used mainly by musicians. Platforms: Mac

This code implements automatic gain control for audio signals, which attempts to apply a smoothly-varying gain to an audio waveform in order to keep its energy close to some target level. This version also tries to balance the energy in individual frequency bands. It works by taking the... Platforms: Matlab
