    • A multi-channel input signal is downmixed to a multi-channel output signal by one of four downmixing routines. The downmixing routines compute the output channels by multiplying each of a number of coefficients by one of the input channels, and then accumulating the resulting products to form the output channels. For efficiency, the four downmixing routines perform various different computations on the input channels using different combinations of coefficients. For a given combination of input and output channels, a downmixing routine is chosen that will perform all of the necessary computations for downmixing the input to the output, while minimizing the number of computations performed with zero-valued coefficients. As a result, computational efficiency is increased by avoiding unnecessary computations, while at the same time, programming effort and program size are maintained at reasonable levels.
    • 通过四个降混程序之一将多通道输入信号下混合到多通道输出信号。 降混程序通过将多个系数中的每一个乘以输入通道之一来计算输出通道,然后累加所得到的乘积以形成输出通道。 为了效率,四个下混程序使用不同的系数组合在输入通道上执行各种不同的计算。 对于给定的输入和输出通道的组合,选择一个下混程序,其将执行所有必要的计算,以将输入下混混入输出,同时最小化用零值系数执行的计算次数。 因此,通过避免不必要的计算,提高了计算效率,同时将编程工作和程序大小保持在合理的水平。
