HIGH PERFORMANCE AUDIO TRANSMISSION CHANNEL

摘要

The invention concerns an audio receiver system comprising: a modulator (1) for modulating a first digital audio signal with a first factor and a second digital audio signal with a second factor greater than the first, said second signal comprising a plurality of words having length of 1 bit over a predetermined time interval; an output device (11) comprising a loudspeaker (10) and means for transmitting the second signal to the loudspeaker (10) in analog form. The invention is characterised in that it further comprises a control device (2) connected to the modulator (1) on receiving the second signal and to the output device (11), the control device being capable of controlling the output device as from part of said predetermined time interval, the length of said part being determined on the basis of the desired volume.
