DEVICE AND METHOD TO GENERATE VALUES OF SUBBANDS OF SOUND SIGNAL AND DEVICE AND METHOD TO GENERATE AUDIO COUNTS OF TIME AREA Russian patent published in 2011 - IPC H03H17/02 G10L19/02 

FIELD: radio engineering.

SUBSTANCE: version of device (100) realisation to generate values of subbands of sound signal in channels of subbands of sound signal comprises facility (PO) of window processing by analysis for window processing of frame (120) from input audio counts of time area, located in sequence of time, stretching from earlier count to later count, using window function (190) of analysis, containing sequence of window coefficients, to produce counts been through window processing. Window function of analysis comprises the first quantity of window coefficients produced from high window function, containing sequence from large second quantity of window coefficients, besides, window coefficients of window function are produced with the help of interpolation of window coefficients of high window function. Device (100) additionally comprises facility (170) of computations to compute values of subbands of sound signal, using counts been through window processing.

EFFECT: increased transmission pass band compared to sound system with higher delay with comparable level of quality.
