VST Equalizer with Phase control?

[poshook]

Any1 knows anything?

[Christian Budde]

Why would you like to adjust the phase? Your ear isn't able to detect most parts of the phase. It's only of little interst in the context of HRTF. Also in transients the phase may be recognitioned.
Usually the two different models 'minimum phase' (keeping transients intact) and 'linear phase' (=constant group delay) are all you'll need to have.

poshook, you could use a liniar phase equalizer - like the both from elementalaudio.com or the curve from voxengo. So, then you don't have to worry about phase trouble.
Best eq i know is the red and orange eq from algorithmix.com

Are you looking for linear phase eq's or and eq with phase controll?
If your looking for the latter, Hydratone from Tritone Digital has a phase controll section in addition to its parametric eq.

I don't think that equium is phase linear, it's minimum phase.

I'll throw this in also for comment - cause I'd like to hear opinions if there are any...

In addition to the controllable Hydratone and free Phasetone - Voxengo CurveEQ has internal impulses in its' gear match section that contain phase information from various outboard gear. HarmoniEQ has a "Phasy" mode. Also some of the hardware impulses at noisevault have phase information which would be a little more controllable in an impulse reverb like pristine or sir. I'm just getting into phasey type stuff a little as it seems to be a percentage of the facts of life anyway. Also as Christian already mentioned it is naturally found in HRTF which has everyday implications of course since that is how your 2 ears and head affect sound in the natural world befor it hits your brain. I use Wave Arts Panorama to experiment here - Christian has something also I believe.

What are you planning on doing with phase control?

Okay, then it was FIRIUM

I always though it would be cool to have complete control over the phase at every point in the spectrum, much like we can control the amplitude with EQs. The phase information is available in the FFT along with the amplitude, so why not have a mode where the user can manipulate it? Sort of a BBE Sonic Maximizer on steroids.

Although I admit I have not studied this area too much to really know if this is a valid idea or not.

In reality, having TOO much of phase control won't give any real benefits. If you apply several cycles of phase shift over some frequencies these freqs will sound like equalizing took place. While when applying half-cycle phase shifting or less you won't really hear anything (AFAIK somebody I do not remember who have proved this on speech signals, in the past).

Basically, in equalizers phase shifting has a predefined pattern which depends on the frequency and filter steepness. It won't be a fun to control such predefined phase shifting manually. On the other hand it's an idea for plug-in developers, to fine-tune phase shifting patterns in equalizers, to get better overall sound.

Maybe more phase control can fix an odd phenomena I had once: a friend played a CD I made on a home cinema set, and unintentionally the vocals were coming out of the back speakers! Could some phaseshifting have caused this?

Interesting - yes that's exactly what I've been trying to do using impulses of actual equipment from your internal impulses in AF, CurveEQ, and the downloadable ones at noisevault. I believe some or all of those impulses contain the captured phase information? At any rate the phase characteristic of some of the eqiup that has transformers, for example, might have a particular sonic signature partially because of phase (I'm guess here). If that's the cause though I'd surely be interested in a tool that could control the level of that sonic signature. I was trying this in Pristine Space last night - I guess I could re-eq the wave file impulse outside of PS but uggh. Anyway - maybe that's different from what poshool needs...

Is this similar to the async control you have in Voxformer - which is an old broadcast "trick" I think?

[Aleksey Vaneev]

Kyle, I guess some of the Gear options in CurveEQ may carry much phase shift.

Async control in Voxformer is just used for compressing positive and negative lobes of the waveform differently. This usually creates 'warm' compression.
