I would like to get some technical examples of EQ algorithm differences. I understand compression algorithms. These can be drastically different. How one digital EQ is actually better then another gets fuzzy. I'm not talking about features or interface but audio integrity.
I have recently switched to sonar 7PE. This has made me reevaluate my plugin arsenal.
I have been using Christian's plugin analyzer to compare my EQ's
Christian’s Blog » Programs
I have been comparing the
Duende channelstrip
urs CSP
Sonars Native mixer EQ
VC-64 (kjaerhus audio GAC-1 port)
& LP-64
The EQ variables that i am aware of are
frequency response
filter slope / Q
& phase
I have been able to recreate the the slope, phase, & sonic characteristic of the Duende & CSP with built in native EQ . Or with any fully variable parametric EQ for that matter.
As i said compressors are a different story. Duendes program dependent comp is it's own beast
Besides linear phase, internal bit resolution, or to free cpu with external DSP i'm now questioning why anyone needs anything but there native EQ.
I can't find technical reasons.
Please inform.
