FIELD: acoustics.
SUBSTANCE: invention relates to audio signal processing. Device for wide bandwidth signal generation from audio signal with limited band pass comprises patches generation module, signals processing module and combining module. Patches generation module is made with possibility of harmonic patching algorithm execution for, to obtain signal after patching. Patches generation module is made with possibility to execute harmonic patching algorithm for current time unit with wide bandwidth from plurality of successive time units with wide bandwidth using time unit preceding in time with limited band pass from plurality of successive time units with limited audio signal band pass with limited band pass.
EFFECT: technical result is improved wide bandwidth signal generation with exclusion of additional delay.
