A reproducing method and apparatus include an audio signal processor, a controller, and at least one decoder. The audio signal processor receives digital audio signals for more than one channel reproduced from a disc, and processes the received digital audio signals. The controller sets at least a first channel for reproduction, and generates a first control signal indicative thereof. The first decoder receives the processed audio signals and the first control signal, and extracts and decodes audio signals for the first channel included in the processed audio signals based on the first control signal.
