Complementary transfer function design of crossover filters in loudspeaker systems

摘要

The invention provides a system and method of designing complementary transfer functions (CTF) [109] for crossover filters that adjust for various crossover considerations. According to the invention, a computer-implemented system and procedure, in a specific audio environment, processes crossover factors [110], designs a CTF filter in a computer simulation [111], correlates measurements of crossover parameters with the computer simulations [112], and adjusts the CTF design [14] until there is a high or predetermined degree of correlation between the computer simulation and the crossover measurements. In particular, the inventive system and method achieves proper blending between chosen sets of subwoofers [105] and satellite speakers [101] in loudspeaker systems.
