Crave EQ provides four high fidelity filter models: Analog, Transparent, Digital (zero latency) and Linear
Analog
It's like enabling infinite oversampling in your DAW only it's much cleverer and more efficient. Enjoy the beauty of analog Butterworth filters without digital side effects like pre-ringing and aliasing. Great for ears that love the natural sound of analog phase filtering. Low latency (48 samples at any sample rate) and ultra-low CPU.
Transparent
Digital wizardry that combines smooth analog filtering in the low end and linear phase processing in the high end. Provides a more cohesive mixing experience as higher frequencies remain in phase across tracks. Great for preserving the integrity of a mix when applying corrective or creative EQ across tracks.
Digital
Our zero-latency digital filter model faithfully maintain its shape up to Nyquist. To achieve zero latency, it introduces more color at high frequencies than the other models due to large phase changes in this region.
Linear
Linear phase filtering comes at the expense of greater latency and, if not carefully applied in the low end, will generate pre-ringing artifacts. Apply this model with low Q and gentle slopes in the mid and high frequencies for colorless, corrective EQ.
The diagram below shows the phase response of the four filter models in Crave EQ (Analog, Transparent, Digital and Linear) for a peaking filter at 5kHz. In this example, the transparent phase model is set to a latency of 5ms. They all exhibit the same magnitude response only differing in phase.
