Another audiophile technique has been employed in the digital processing core of the DacMagic, namely upsampling. Like the upconversion of standard definition video to eye-opening HD, this techniques repackages a typical 16-bit/44.1kHz music feed as you'd find from a CD or music MP3, into 24-bit/192kHz format.
This upsampling approach was once limited to professional converters costing upwards of £4000 each, and while it's now possible to do a basic conversion with cheap chips, Cambridge Audio has called upon the expertise of Swiss DSP specialist Anagram Technologies, to do the job in a way that can potentially upgrade the sound of all your music sources.

Its proprietary interpolation algorithm runs on a Texas Instruments 32-bit processor, helping to fill out the discontinuities in a jagged, stepped 16-bit digital waveform, bringing it closer to the sound of high-resolution 24-bit sound. The actual D-A conversion is courtesy of a pair of renowned Wolfson stereo DAC chips.
