Abstract: An apparatus and a method for efficiently converting, by means of mixdown, audio signals recorded in multiple tracks into stereo signals. A plurality of audio signals input from an input terminal are recorded into a plurality of tracks of a recording medium. A mixer reads the audio signals recorded in the multiple tracks, subjects the audio signals to mixdown according to a mixer parameter set by an operation section, and records the processed signals as audio signals in the recording medium without reproducing the processed signal in real time. A plurality of mixer parameters are set, and a user can select a desired mixer parameter.

Abstract: An audio mixing method includes: performing an audio processing operation upon a first audio input derived from at least one decoded audio input to generate a processed audio output, and generating a mixed audio signal by mixing at least a second audio input and the processed audio output. An audio mixing apparatus includes an audio processing circuit and an audio mixing circuit. The audio processing circuit is utilized for performing an audio processing operation upon a first audio input derived from at least one decoded audio input and accordingly generating a processed audio output. The audio mixing circuit is coupled to the audio processing circuit, and utilized for generating a mixed audio signal by mixing at least a second audio input and the processed audio output.
