1. A signal processing device comprising:
processing circuitry configured to:
generate a signal of a reverb component on a basis of object audio data of an audio object and a reverb parameter for the audio object; and
perform rendering processing on the signal of the reverb component on a basis of the reverb parameter, wherein the reverb parameter includes a pre-delay delay time that indicates a delay time to when reflection sound or reverberation sound other than early reflection sound is first heard relative to a time when direct sound is heard and an early reflection delay time that indicates a delay time to when early reflection sound is heard.
