Dynamic Time Warp (DTW) in Matlab  
The code and example on this page show a simple implementation of dynamic time warp alignment between soundfiles. In addition to using this for scoring the similarity between sounds, we can also use it to `warp' a soundfile to match the timing of a reference, for instance to synchronize two utterances of the same words.

VTAR - Vocal Tract Acoustic Response Calculation  
VTAR is a MATLAB-based computer program for vocal tract acoustic response calculation. Based on a frequency-domain vocal tract model [Zhang and Espy-Wilson, 2004, J. Acoust.Soc. Am., 115(3), 1274], VTAR is able to model various complex sounds such as nasals, rhotics and liquids.

ACUSYS -Simulation and analysis of pressure pulsation in complex piping and plants  
ACUSYS, developed using MATLAB and Simulink, simulates the stationary and transient response of the fluid medium inside a piping network, induced by pressure or flow pulsation's applied to discrete points. ACUSYS simulates the fluid medium as a monodimensional linear wave field electro-acoustic analogy), optionally with variable sound speed, bounded in pipes, containers, and piping accessories.

PSonE2 and PSonE3 - Design and evaluation of passive sound transmission for multi-layer structures  
PSonE2 and PSonE3 are programs that offer detailed evaluation of sound transmission for multi-layer structures represented by flat panel models. PSonE2 evaluates the acoustic signal gain for various acoustic environments, coating layers, vehicle depth, and incident pressure load for a two-layer model.
