Sorry for misinformation regarding audio suite. I only have version 1.

Idris, the thing with Izotope Radius is that it is only stereo at max - so phase consistency within a 5.1 mix is not given.

It did sound great in one of my tests though, and there is a thread on Gearslutz with Aleksey (an Izotope developer) giving advice on how to tweak the parameters for different artefacts.
Generally when I did a shootout I found it to sound very good on my test material, albeit only on the stereo downmix of course.

Really hoping the clever brains at Izotope find a way to go multichannel with it some time.

Mike - a shootout would be awesome!
Things to keep in mind though: 24-25 and 25-24 are two different scenarios with their own difficulties...

Do you have a link for that? I've tried several searches, but can't find anything obvious. (Is the spelling of his user name correct?)

I'm late to the party. I only tried X-form once and it was so slow . Timefactory is great. I've tried Elastique real-time but had no idea the new version was Audiosuite. Thanks for the heads-up!

Some day would like to try Time Factory
Wanted to report back that I finally had an opportunity to purchase Time Factory 2 to process STEMS for a 23.976-->25 Film Style pull up. I used SRC to get everything in time. Then I put those stems into TF2 and selected the appropriate settings for each type of Stem (DX, FX, MX). I also had used X-Form to process same stems for comparison.

I must say that on every stem, TF2 sounded superior. The music stem was really good. Impressed.

HOWEVER, at an appropriate setting for music -- ZTX/Classics(l=5)/Best -- the processing time took over 5 hours. So, not FASTER. But I am happy with the results!

I use TF2 all the time for all frame rate conversion tasks. Don't bather to SRC first but let the TF2 to do the job. Its especially good for 25 to 24fps conversion.
Having said that I prefer sometimes P 'n T for music stems and particularly for slow piano and strings material.
Didn't touch my X-Form for years now, even though TF2 takes time as you noticed.

Default Re: X-form and pitch shifting

I'd like to resurrect this thread as it hasn't been commented on since 2016. I'm currently looking to pitch shift some 5.1 stems after doing an SRC to convert from 23.976 to 25fps. The SRC is complete and now I need to pitch back down to the original pitch.

I've tried Izotope RX 8 Time & Pitch (Radius setting) which sounded terrible. I also tried a demo of Elastique Pitch V2 which also sounded terrible. When I say terrible I mean robotic and totally unusable.

I finally tried X-Form (which I never liked in the past) out of desperation and it sounded surprisingly good on both 5.1 dialog stem and music stem; monophonic and polyphonic settings respectively.

I have yet to try Pitch n Time Pro as I can't find a demo on their site...am I missing it?

Can anyone steer me in the right direction here as to the best pitch shift plugin for audio post (specifically pitch shifting 5.1 mix stems as described above).

Thanks for your help.
