METHOD AND DEVICE FOR CONTROLLING REPRODUCTION OF AUDIO-SIGNAL BASS COMPONENTS IN ELECTRO-ACOUSTIC TRANSFORMERS Russian patent published in 2006 - IPC H04R3/04 

FIELD: acoustics, in particular, technology and device for controlling reproduction of audio-signals in electro-acoustic transformers.

SUBSTANCE: method, realized by means of device for controlling reproduction of audio-signals in electro-acoustic transformers, includes selecting frequency components of audio-signal and amplifying them with amplification coefficient, calculated on basis of audio-signal, joining them with audio-signal in a way to produce modified audio-signal, which is sent to electro-acoustic transformer. By means of filter with terminal pulse response or filter with infinite pulse response, or single band filter, band filtering of audio-signal is performed for selection and amplification of first frequency component, low-frequency filtering and/or band filtering of audio-signal is performed for selection of second frequency component, contouring line and/or energy of unfiltered, subjected to low-frequency filtering and/or band filtering, audio-signal, is calculated.

EFFECT: improved reproduction of audio-signals bass components.
