Estimating the term…
Disclosed are an audio rate conversion system and an electronic apparatus. The audio rate conversion system includes an integrator-comb filter, a multi-rate filter and a first half-band filter, an input of the integrator-comb filter being accessed with digital audio data, an output of the integrator-comb filter being sequentially connected to the multi-rate filter and the first half-band filter; where, the integrator-comb filter is configured to reduce a rate of the digital audio data according to a preset decimation rate; the multi-rate filter is configured to convert a rate of digital audio data output by the integrator-comb filter into a rate of digital audio data corresponding to an accessed control signal according to the control signal; and the first half-band filter is configured to reduce a rate of digital audio data output by the multi-rate filter.
