Matlab Toolboxes

fdtools  Fractional Delay Toolbox for Matlab

This toolbox provides a set of MATLAB routines that can be used to
design fractional delay FIR and allpass filters and to plot their responses.
The basic MATLAB and the MATLAB Signal Processing Toolbox are needed.

warp  Warping Toolbox for Matlab

WarpTB is a MATLAB toolbox for frequencywarped signal processing.
Practically any signal processing algorithm can be warped by replacing all the unit delay elements by first order allpass blocks.
Frequencywarping changes the frequency resolution of the system. Using a suitable value for a warping coefficient LAMBDA,
the frequencyresolution of the system approximates closely the frequency resolution of human auditory system.
This makes frequencywarped signal processing techniques beneficial in many speech and audio signal processing applications.

Matsig  An objectoriented signal processing class library for MATLAB

Matsig is an objectoriented signal class library for MATLAB 6.5 and later. It implements a signal class, simplifying operations and manipulations common in audio signal processing and speech processing.

Aparat

Aparat is a software toolkit and graphical user interface for glottal
inverse filtering and glottal flow parametrisation. It works in MATLAB
environment, using MATLAB 6.5 or later.

Other Software

VBAP software

Vector Base Amplitude Panning (VBAP) is a method for positioning virtual sources to multiple loudspeakers.
The number of loudspeakers can be varying and they can be placed in an arbitrary 2D or 3D positioning.
VBAP produces virtual sources that are as sharp as is possible with current loudspeaker configuration and
amplitude panning methods, since it uses at one time the minimum number of loudspeakers needed, one, two,
or three. The VBAP method has been developed by Ville Pulkki
