Elastic Audio on Multi-Miced Electric Guitars... PLEASE HELP!!!

[dglennjr]

I started using elastic audio the day it came out and won't ever use beat detective again for tempo correction on drums... I LOVE IT! However, recently on my HD 2 system I've noticed when I try and manipulate a multi-miced guitar i'm getting phasing issues like crazy... The thing that's driving me crazy is I have all 3 mics grouped, I'm using the Polyphonic Algorithm and this method works perfectly on drums and other multi-miced sources as far as I have come across... (of course using the rhythmic algorithm on drums)...

Anyone else have any issues with MULTI-Miced guitar amps? These guitar parts in particular happen to be very overdriven. I used an SM57, an AKG Solidtube and a Sennheiser E609 to mic a Vox AC15 HTV amp.

If I left anything out or you want to know more about my setup let me know.

All help is greatly appreciated!

God Bless,

Hey David, I'll experiment tomorrow, but I can see, with as "Constant, and Saturated" an electric guitar is, if EA is doing ANYTHING different to the algorithm on one of the other tracks, I can imaging the phasing, quite intense.

I'd actually play with "Rhythmic" mode for these grouped guitars, as this mode really applies a series of Crossfades, and doesn't "Process" or Alter the audio.

It's also VERY important that you create an edit group to keep phase coherency when using EA, be it Drums or Guitars. Try that and see if it helps.

As Kingfish said Poly and Rhythmic operate in different ways. Poly will stretch audio more whereas Rhythmic operates more Beatdetectivy (new adjective) Take a tom(or any other drum with longish tail) and try both stretching to +400% and see what happens.

What happens if you use the Mono algo

personally I don't think it works well for multi mic'd drums either.

But the way I do it is I go through and eliminate all the *analysis* markers and drop them in by hand across the group as a whole. I don't trust the way it puts in analysis markers on some tracks but not others, or at different points in the waveform. I've had the best sound (less phasing) this way, but you have to be very careful about watching out for funny attacks. Of course, with guitars.... if you didn't track a DI and they're distorted you're pretty much SOL b/c trying to figure out where the analysis markers (and subsequent warps) go will be like trying to find a needle in a haystack.

I use EA on multi-tracked drums all the time. It works really well for me. I am currently working on a session where the drummer played a Kick a little early, fixed it in no time flat and no artifacts. If the drummer is good, pocketing is REALLY easy with it.

Thanks so much for the replies!

I'll be back on the project where this became a big issue tomorrow/well today... I'm going to give it a whirl using the rhythmic algorithm.

Has anyone been using EA for multimiced guitars successfully?

A side note... I also recorded the DI signal from the guitar and have Eleven... I LOVE IT!!! So worst case scenario I would Elastic Audio those tracks and either send them back out to the amps or use Eleven... BUT! it would be less time consuming if Elastic Audio would work on the miced guitars...

Thanks again!

Thanks! I'm going to give Rhythmic a try later today. You know what... I just recalled a session I did with guitars and I did use rhythmic!!! it worked great for tightening up 2 guitarists palm muting... However, I don't think they were multimiced and they were definitely overdubbed at seperate times so a little different scenario... I'll let you know how it goes tonight.

Thanks for the response... I guess I could've been clearer in the original post, but the guitars are grouped into an edit/mix group with all appropriate attributes assigned.

Have you had any luck using EA on multi-miced guitars?

Thanks again,

I guess I should have had a better engineering thought process to not restrict myself to the algorithms that are recommended by digi :)

I will definitely give it a test run here soon and let you know if any of the other algorithms work in my situation...

Thanks and God Bless,
