1. An information processing device comprising:
circuitry configured to function as:
a high-precision component extraction unit that:
acquires, as an unprocessed signal, a digital signal not subjected to predetermined signal processing and having a first quantization precision, and
extracts, from the unprocessed signal, high-precision component information regarding signal components included in the unprocessed signal; and
a quantization precision reproduction unit that:
acquires, as a processed signal, a digital signal obtained by performing the predetermined signal processing on the unprocessed signal and having a second quantization precision reduced from the first quantization precision, and
generates a reproduction signal in which the quantization precision of the processed signal is reproduced to the first quantization precision on a basis of the high-precision component information without using the unprocessed signal as a direct input to the generation of the reproduction signal.
