摘要： The present technology relates to a signal processing device, a signal processing method, and a program that allow for easier sound source separation.
The signal processing device includes a sound source separation unit that recursively performs sound source separation on an input acoustic signal by using a predetermined sound source separation model learned in advance to separate a predetermined sound source from an acoustic signal for learning including the predetermined sound source. The present technology can be applied to a signal processing device.

摘要： For example, digital watermark information can be appropriately extracted.
An information processing apparatus includes a decoder that extracts, using a certain learning model, additional information included in a mixed sound signal where a plurality of sound source signals is mixed together. A change in the sound source signals and the mixed sound signal caused by addition of the additional information is imperceptible.
