Abstract
The disclosure provides a crosstalk canceling system and method, and a sound processing apparatus, and the system includes: a sub-band filter component configured to frequency-divide an original audio signal transmitted over a sound channel of the multimedia device into sub-band signals, and to delay and apply gains to the sub-band signals according to preset delay values and gain values corresponding to the sub-band signals; a synthesizer configured to generate a crosstalk canceling signal from the sub-band signals which are delayed and to which the gains are applied; and a signal generator configured to generate a play signal of another sound channel than the sound channel from which the crosstalk canceling signal is derived, according to the crosstalk canceling signal, and an original audio signal of another sound channel than the sound channel from which the crosstalk canceling signal is derived, thus canceling crosstalk in effect.
