Dynamic Time Warp (DTW) in Matlab  Update Link / Bad Link
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  Update Link / Bad Link
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.

Free Online MathWorks Seminar: Fixed-Point Digital Audio Processing using the Signal Processing Blockset    Update Link / Bad Link
Simulink�, when combined with the Signal Processing Blockset, enables engineers to quickly and effectively create bit-accurate product-level and algorithm-level specifications. This webinar will explore finite-word-length effects on system performance and other design trade-offs when moving from floating-point to fixed-point data types.

ACUSYS -Simulation and analysis of pressure pulsation in complex piping and plants  Update Link / Bad Link
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  Update Link / Bad Link
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.
