does it exists ? software phase alignment tool ?

Hi Jonathan,

When it says that each frequency is shifted by the same amount, I mean that each frequency's phase is shifted by the same amount relative to its wavelength. If you are applying a shift of PI radians for instance (half a cycle of the wave), then a 100Hz wave has to be shifted twice as far in the time domain as a 200Hz wave, since its wavelength is double the size, in order to have the same effect on phase.
So in other words, yes each frequency does get shifted differently, so its not doing a simple time shift.

Please produce this for Mac OSX and PT.

Please ...

Ive been using the voxengo since it came out, cool for what it is, I'm also not afraid to slide some tracks around to try things out and that is useful sometimes too.

But lately Ive been wanting to do my adjustment as I track,so I bought a IPB a few days ago just as I started tracking a new album, so far its lived on the bass DI insert post the 2", as i am still learning its strengths. Ive been twiddling the knob around and finding a few cool spots I like. the one thing I found I liked doing is adjusting while listening to the whole band playback rather than just soloing the bass, you really hear the bass change shape and fit differently in the mix.

So once I'm used to it for a bit longer I will be printing stuff IPB'd in real time the way I want, as I love being able to pull up a multi and have it all there, rocking and ready. no software plugs or time adjustment needed.

Hi, there seems to be several people asking for a Mac version of PhasePhix.. While I would like to support the Mac platform, my problem is that I don't have the resources to do that right now. I'm a PhD student so even a Mac Mini is beyond the spare cash I can spare right now! If my PC plugs do well (PhasePhix but mainly my Soup additive synth) then I can justify investing in expanding to the Mac platform.

Until then, the PC VST are in luck since they can get their hands on PhasePhix and Soup.

I'm obviously struggling whit this concept.
Could someone please explain why (or when) you would want to do this? I don't know if they are describing the same thing, it seems to be a way to advance or retard the arrival time of different frequencies. Is it correcting a phase problem (other than time alignment) or a way to alter the signal in a euphonic way? If it is a 'fix, what causes a signal get out of alignment (or phase) with it's self?

As always, a big thank you to all.

This tool is intended as a 'fix' as you say. It is for when you record an instrument using 2 microphones for example, and you want to align the phase of the signal of the 2 mics. If the phase of the 2 signals is not well aligned then some frequencies add up while others cancel out, so the sound becomes coloured. Of course if you just record an instrument using only 1 mic then phase alignment is not an issue as you only have 1 signal.

Statements have been made in this thread to the effect that these tools (IBP or this s/w) do what can not be done by simply having moved the mics prior, or sliding tracks after the fact. It also seems to me that they may be altering the phase relationship vs. frequency of the effected signal. Could it be that if you want to do time shift via analog, this is just one of the side effects?
I'm trying to pin down when or why you would want to include these functions that go beyond simple time realignment.

If both mics were picking up exactly the same sound then time-shifting would work perfectly, but of course the 2 mics each record a slightly different sound (which of course is the point of using 2 mics). You can't use a time shift to match up 2 different waveforms, some parts line up but some don't.
Now the phase-shift technique can't match them up perfectly either, but it does often give a better match and better sounding results.

It's useful for mono sources as well.

is phasetone almost done, looks good.
