System and method for processing audio signals
View Patent ↗A system for processing audio signals is disclosed. The system comprises a computer with a digital audio workstation (DAW) software installed, an audio interface coupled to or integrated with the computer, an analog audio processor (AAP) hardware coupled to the audio interface. A digital audio stream from within the DAW software is converted, via the audio interface, to an analog audio signal, then routed through the AAP hardware for fully analog processing and altering, then converted back, via the audio interface, to an altered digital audio stream and finally routed back to the DAW software. The DAW software comprises an AAP plugin which controls a number of audio processing settings of the AAP hardware via a control connection between the AAP plugin and the AAP hardware. The AAP plugin comprises a digital signal processor (DSP) subroutine which applies digital audio effects on the previously altered digital audio stream.
