An audio-mixing apparatus and processing method reduces the time for audio-mixing and the PCM conversion processes and reduces memory capacity. The audio-mixing apparatus has a memory for storing a mixing data piece generated from an operation data piece which precedes a different operation data piece being processed at present, a mixing processor for performing a mixing process of the different operation data piece and the mixing data piece read out of the memory to generate a different mixing data piece, and a PCM converter for sequentially performing a PCM conversion process of the mixing data pieces to deliver PCM output data piece.
