Howtosignalprocessing
Here's a table with the main differences of each topology:
| Minimum Phase | Linear Phase |
|---|---|
| – Usable in every situation | – Usable in some situations |
| – Adds color and depth to the sound | – Transparent, artifact-free processing |
| – Delays only the frequencies being processed | – Delays all frequencies simultaneously |

What is minimum phase filter?
Minimum phase filters sometimes are called minimum energy delay filters because the energy of the impulse response is maximally concentrated toward the beginning of the impulse response. All zeroes in a maximum phase FIR filter are outside or on the unit circle.
Should I always use linear phase EQ?
Note: Use the Linear Phase EQ where phase coherence between tracks is needed, such as multi microphone recordings. The Linear Phase does not introduce any phase shift to the signal which can also be beneficial in mastering, but it does impact on the onset of the transient.
What is meant by linear phase?
In signal processing, linear phase is a property of a filter where the phase response of the filter is a linear function of frequency.
What is minimum phase in audio?
So low frequencies can be delayed with respect to high, or vice versa, depending on how the EQ parameters are set. We call this 'phase shift'. 'Minimum phase' means that the amount of phase shift that happens is as little as possible.
