Abstract

An audio DAC with internal DSP core has been designed that includes three high-quality audio DACs as well as a DSP programmed to provide algorithms that correct for speaker/amplifier deficiencies. These algorithms include equalization, two-band compression/limiting with arbitrary compression curve, spatial enhancement, delay and interpolation. All signal processing parameters are register-programmable using an external microcontroller. The DAC architecture uses a multi-bit sigma-delta design with a mismatch-shaping scrambler.
