c'mon, let's admit he had come to the point where his posts were frankly funny.Ībout phase, distortion and artifacts induced by EQ processing: a good way to get an idea of what's happening is to test different EQ plugs on a pure sweeping sine wave (download the one here. In the end I would be carefull, If phases run apart to far, then it starts to sound washed out. We can use look ahead or delay a whole mix a couple more millisecs to line everything up. If u have a couple of higher order filters in a row, than this becomes very significant.Īnd in recording we often have the luxury of not having to do stuff in hard real time. So a min phase filter often has the largest phase spread over the spektrum. Linear vs min phase mostly define how the rest of the spektrum is delayed. Some part of the freq spektrum will have a latency when passing though a filter. Oftern they are somewhere in between.Īlso It can be argued how much this latencies matters. phase filter have to introduce further terms to also delay all frequencies more or less, to end up with a const group delay.īut I would be carefull when one calls normal EQ's min phase, cause that could be the case but doesn't not necessarily is the case. It has the neg that has more latency than the other ones.Ī line phase filter is basically the digital version of bessel fitlers in the analog domain - in their purpose. I like the line phase eq, sounds a bit clearer than the normal one. like the Waves Linear Phase EQ for instance. Just because an EQ is Linear Phase doesn't mean it won't have terrible ringing filters, etc. I much prefer so-called minimum phase EQs instead of Linear Phase, as they sound more natural to my ears. Now observe the headroom on the channel and see which one changes the least.
40 Hz, one in the regular EQ and one in the Linear Phase EQ. The upside can be more headroom as phase relationships won't change like normal EQ. This means you sometimes need to apply more EQ in a Linear Phase to get the same effect as boosting in a regular EQ. Linear Phase can appear more transparent - or just different.
We simply often like the sound of a regular EQ or the so-called minimum phase EQ such as the Flux Epure. While this would supposedly sound better it's mostly theoretical as we are used to the phase changes of regular EQs. Linear Phase maintains the phase relationship between various frequencies, unlike a regular EQ.
