Filters - Cambridge Audio Upsampling Digital to Analog Converter azur DacMagic User Manual

Filters

The DacMagic DSP has three different Filter functions: Linear Phase, Minimum Phase and Steep. All
three filters are highly sophisticated audiophile topologies, optimised specifically for audio playback.
In our opinion, these filters offer excellent sound quality but differ subtly in optimisation, hence we've
made all three available to you.
For clarity, all diagrams show the theoretical response of the DSP itself, excluding any analog
filtering at the DAC output or the anti-aliasing filter applied during recording and/or mastering of the
digital source.
