AUDIO SIGNAL PROCESSING METHOD AND AUDIO SIGNAL PROCESSING APPARATUS THEREFOR |
摘要 |
An audio signal processing apparatus and method are provided. The apparatus includes a stability determiner and a sigma-delta modulator. The stability determiner divides a frequency band of an input audio signal into one or more sub-frequency bands, compares a level of the input audio signal for each of the sub-frequency bands with a threshold for the sub-frequency band, and generates a stability determination signal according to a result of the comparison. The sigma-delta modulator sigma-delta modulates the input audio signal according to the stability determination signal, and outputs a modulation signal. |
