Welcome to the CNAQ project !
CNAQ : a MATLAB acquisition tool to measure and compute transfer functions and impulse responses over audio cards
Description
CNAQ is an open source software dedicated to transfert function measurement of electronical, mechanical or acoustical systems. It is written in MATLAB language and uses simple audio cards compatible with ASIO drivers to generate and acquire the signals. Using the Angelo Farina's swept sine technique to compute the transfert functions in the time or frequency domains, CNAQ is able to give VERY high frequency resolutions, even at low frequencies. Moreover, this technique allows to compute the harmonic distortion levels easily.
