摘要：
User is allowed to designate a desired mode defining the respective numbers of channels and mixing buses, and processing for mixing input signals of the number of channels corresponding to the designated mode is performed repetitively to generate signals for the individual buses. The time of arrival of the last step in the mixing processing for the number of channels, corresponding to the designated mode, is detected to output an accumulation result obtained at the last step, and new accumulation is started with a digital audio signal inputted at a step following the last step. Digital audio signals processed by a first signal processing circuit are stored into a memory and transmitted to a second signal processing circuit via a cascade-connection. The second signal processing circuit adds the audio signal, processed for each of the steps, to audio signals input via the cascade-connection and writes added signal into the memory.
摘要（中）：
允许用户指定定义相应数量的通道和混合总线的期望模式，并且重复地执行用于混合与指定模式相对应的通道数量的输入信号的处理，以产生用于各个总线的信号。 检测对应于指定模式的通道数的混合处理中的最后一步的到达时间，以输出在最后步骤获得的累加结果，并且以在 在最后一步之后。 由第一信号处理电路处理的数字音频信号被存储到存储器中，并通过级联连接发送到第二信号处理电路。 第二信号处理电路将针对每个步骤处理的音频信号添加到经由级联连接输入的音频信号，并将附加信号写入存储器。
