An audio signal transmission system includes an input section, an output section and a transmission section interposed therebetween. The transmission section analyzes the spectrum of the input audio signal and performs signal processing based on the result of this analysis and in accordance with the physical response characteristic of the output section.

DETAILED DESCRIPTION It is therefore an object of the present invention to provide an audio signal transmission system which is capable of producing a high-fidelity output.
po To achieve such an object, according to the present invention, there is provided in one aspect an audio signal transmission system comprising: (a) an input section; (b) an output section; and (c) a transmission section for transmitting an audio signal between said input and output sections, said transmission section including: first means for analyzing the spectrum of the audio signal input by said input section; and second means for processing the audio signal on the basis of the output of said first means and in accordance with the physical characteristics of said output section.
Another object of the present invention is to provide an audio signal transmission system which is capable of realizing the desired frequency characteristic of the crossover network, setting the crossover frequency freely and minimizing distortion due to the crossover network.
To achieve such an object, according to the present invention, there is provided in one aspect an audio signal transmission system comprising: (a) an input section; (b) an output section including a plurality of output means having different physical response characteristics; (c) a transmission section for transmitting an audio signal between said input section and said output section, said transmission section including first means for analyzing the spectrum of the audio signal input by said input section; and second means for dividing the audio signal into a plurality of subaudio signals in accordance with the output of said first means, which subsignals are supplied to the corresponding ones of said output means of said plurality.
Other objects and features of the present invention will be apparent from the following detailed description of embodiments thereof when taken in conjunction with the accompanying drawings.
