Title: SIGNAL PROCESSING DEVICE, METHOD, SPEAKER AND ELECTRONICS APPARATUS
Abstract:
A signal processing device, a signal processing method, a speaker and an electronics apparatus. The signal processing device comprises a multi-band dynamic range controller, wherein the multi-band dynamic range controller receives an audio signal (S1100) and includes a first band splitting unit and a resonant band adjustment unit; the first band splitting unit is configured to split the audio signal into multiple bands and obtain at least one resonant band therefrom (S1200), which has a resonant frequency band signal in a resonant frequency range of the audio signal; and the resonant band adjustment unit is configured to adjust the resonant frequency band signal based at least on a resonant band dynamic range control gain (S1300) and output an adjusted resonant frequency band signal (S1400) for combination with other band signals into a compression output signal.
