Abstract:
A process for mixing digital audio signals from a plurality of inputs into a plurality of outputs comprising:formatting incoming parallel signals composed of data words so that the data words are supplied in an order of lowest value bit to highest value bit;word-wise and bit-wise synchronizing of the formatted parallel audio signals data;adding the synchronized formatted parallel audio signals in bit-wise fashion;selecting one of the formatted incoming parallel audio signals;dividing the one audio signal into a plurality of equivalent parallel signals;forwarding one of the plurality of equivalent parallel signals to a multiplier;successively bit-wise delaying each of the remaining plurality of equivalent parallel signals;forwarding each successively bit-wise delayed parallel signal to a respective multiplier;multiplying the one parallel signal by a lowest bit of a factor for adjusting the one audio signal;multiplying each successively bit-wise delayed parallel signal by a corresponding next bit of the factor; andbit-wise adding the factored one parallel signal and the factored successively bit-wise delayed signals to produce the adjusted one audio signal.
