    • A music sound generation apparatus generates music-sound data based on sound source data, and outputs the music-sound data in synchronization with audio data obtained separately from the music-sound data. A channel assigner assigns a predetermined number of channels to the audio data and the music-sound data. A read control unit reads the audio data and the music-sound data in accordance with their assigned channels. A signal processing unit generates predetermined music by controlling the sound level of the read audio data and the read music-sound data on each assigned channel and mixing the audio data and the music-sound data. When detecting no unoccupied channel, the channel assigner determines, as an unoccupied channel, a channel selected from channels excluding the channel to which the audio data has been assigned. The signal processing unit performs sound elimination on the unoccupied channel.
    • 音乐声音产生装置基于声源数据生成音乐数据,并且与音乐数据分开地获得的音频数据同步地输出音乐数据。 频道分配器向音频数据和音乐声音数据分配预定数量的频道。 读取控制单元根据其分配的频道读取音频数据和音乐数据。 信号处理单元通过在每个分配的频道上控制读取的音频数据和读出的音乐数据的声级并且混合音频数据和音乐声音数据来产生预定音乐。 当检测到没有未被占用的信道时,信道分配器将未被占用的信道确定从除已分配音频数据的信道之外的信道中选择的信道。 信号处理单元在未占用信道上执行声音消除。
