Abstract
An audio processor may process dissimilarly formatted digital audio signals and produce an analog output for reproduction by a transducer, such as a speaker. The audio processor may be, for example, a digital-to-analog converter (DAC) with multiple digital inputs and a single analog output. The audio processor may also include other components, such as processing components, filters, equalizers, amplifiers, and the like. The audio processor may process audio, such as high fidelity DSD audio and lower fidelity PCM audio, and combine the differently formatted data into a single output. During processing, the audio processor may manipulate the different audio signals, such as by ducking a music playback to allow a notification sound to be played.
