Abstract
Circuit, method for audio signal processing with excursion estimation compensation, and non-transitory storage medium are provided. The circuit comprises a delay circuit, compensation filter, excursion estimator, peak detector, gain determination circuit, and gain adjustment circuit. The delay circuit is for delaying a digital audio signal to output a delayed digital audio signal. The compensation filter is for generating a compensated digital audio signal according to the digital audio signal for excursion estimation compensation for a speaker type. The excursion estimator is for determining an estimated excursion signal for the speaker type according to the compensated digital audio signal. The gain determination circuit is for generating a gain setting signal according to the estimated excursion signal and a threshold value. The gain adjustment circuit is for generating an adjusted digital audio signal according to the gain setting signal and delayed digital audio signal.
