Sony patents system that splits music to control automatic instruments
Sony describes a signal processor that takes a mixed audio track and separates it into individual sounds like drums or vocals. It then identifies what type of sound each part is and sends it to the right device, such as an automatic musical instrument or a standard speaker.
In the filing’s own words
Provided is a signal processing apparatus having: a sound source separation unit configured to perform sound source separation on a mixed sound signal obtained by mixing a plurality of sound source signals; a sound source type determination unit configured to determine a type of a predetermined sound source signal obtained by the sound source separation; and an output destination control unit configured to output the predetermined sound source signal to a corresponding output device on the basis of a determination result of the sound source type determination unit.
What exactly they claim (claim 1)
1. A signal processing apparatus comprising: circuitry configured to: perform sound source separation on a mixed sound signal obtained by mixing a plurality of sound source signals; determine a type of a predetermined sound source signal obtained by the sound source separation; and output the predetermined sound source signal to a corresponding output device in a plurality of output devices on a basis of the type of the predetermined sound source signal, wherein the circuitry acquires reproduction apparatus information indicating a type of each of the plurality of output devices, and decides the corresponding output device that outputs the predetermined sound source signal by matching the type of the predetermined sound source signal with the type of the corresponding output device indicated by the reproduction apparatus information, wherein the plurality of output devices includes at least one automatic playing musical instrument, wherein the plurality of output devices includes a speaker separate from the automatic playing musical instruments, and wherein the plurality of output devices includes a headphone separate from the automatic playing musical instruments, wherein the circuitry is connected to the plurality of output devices by wire or by wireless connections.
