Title: SIGNAL PROCESSING METHODS AND APPARATUSES FOR ENHANCING SOUND QUALITY
Abstract:
Disclosed are signal processing methods and apparatuses for enhancing sound quality. A signal processing method of a transmission apparatus comprises: a step of determining a valid bandwidth on the basis of a plurality of parameters for encoding an input signal; a step of preprocessing the input signal on the basis of the determined valid bandwidth; and a step of encoding the preprocessed input signal in accordance with the determined valid bandwidth. A signal processing method of a reception apparatus comprises: a step of decoding a bitstream or a packet received via a transmission channel; a step of determining a valid bandwidth on the basis of a plurality of parameters used in the decoding; and a step of postprocessing a decoded signal on the basis of the determined valid bandwidth.
