METHOD OF SEPARATE SYNCHRONOUS REPRODUCTION USING SINGING DOLL, CONTROLLED FROM SMARTPHONE OR COMPUTER Russian patent published in 2020 - IPC A63H3/28 

FIELD: physics.

SUBSTANCE: this method of separate synchronous reproduction of musical and other audio compositions is used for toys (including dolls) or other entertainment, developing or training devices. Its distinctive feature is separate reproduction by toys of voices or musical instruments belonging to prototypes, to accompaniment (instrumental), sounding on separate device – smartphone, computer or any other sound-reproducing equipment. Ensemble (group) performance of a musical or other audio composition is divided into channels which reproduce separate sound streams from separate musical instruments or persons. Traditional form of reproduction of a previously recorded audio stream involves separation either over spatial channels (two – stereo, four – quad, etc.), or on a frequency band (high, medium, low frequencies, etc.). Within the framework of this patent, a method for separation of a sound source belonging to a person, a musical instrument, a group of musical instruments, vocalists and other sound sources is proposed. Application of this method is possible both in autonomous mode of operation without connection to Internet (in this case audio recording is stored directly on smartphone or computer), and in mode of interaction with server component, when audio recording can be obtained from special database via Internet.

EFFECT: such method most adequately implements reproduction of previously recorded audio materials.
