DNR with DSP

DNR (digital noise reduction) with DSP (digital signal processing)

The goal is to build an audio sub-system in a separate enclosure that can be used by any receiver by simply plugging it into the
receiver's speaker or headphone jack. The audio from the receiver will start out in a preamp/limiter then into a DSP module that
will digitally reduce noise level and then go into an audio filter with user selectable bandwidths and then at last into a power
amplifier that will drive 8ohm speakers.
