Help best Plug-in/algo for Time Stretching Full Mix

[Dom & Roland]

izotope radius is the best i have found... using it in logic would be easiest. It is also used in pro tools 10 but it takes ages. (in protools its called xform i think)

Thanks!

I have just tried with TIME SHIFT by PT HD 8.1.1 and SPEED by Sound Toys.

Preferred the Time Shift version for a compression of time around 4 seconds (1.63%).


I will investigate your other options.


BTW.. Does time shift internally use elastic audio algorithm?

I've used Elastic Audio (X-Form) for years on multitrack sessions and 2 tracks. No artifacts at all with big tempo jumps.

1. set to ticks
2. change tempo with polyphonic till you are comfortable with tempo
3. Change EA to X-Form. Go get some coffee til it's ready.

X-Form is very, very good and uses the Izotope Radius algorithm.

Hi, Tested Waves Sound Shifter Going from 128 to 132 BPM.
Mode Transient, Link Mode Time.

Very similar result to the one with Time Shift.
I am going to try other modes here ( Mode sync, punch... link mode strapped).

At this moment I am trying Elastic audio> Polyphonic Stretch > X-Form.

Just one questions: a) I selected Maximum Quality, formant enable.
Is it fine?

b) I selected commit file when disabling Elastic Audio. I could not see any activity, even at analysis screen. Strange!

I like the result!

Thanks for the tips.

Thanks

I have never found sound shifter to be very good at this as it changes the stereo image and doesn't preserve timing either, often making things sound looser... Xform is the one!

Is Radius included in Logic Pro (9)?
Or do you have to buy in as an add-on?

Does it work in the Pitch&Time-Machine only or is it also available for Flex-Audio?

Do you have the ability to vari-speed with a Sync I/O?

it is a paid add on and it only works in pitch time machine.

I actually never use commit. Takes too long. I always highlight and consolidate. Then when u disable EA, it disables instantly.

I also recommend Radius.

[yoink]

The Radius algorithm is also available in iZotope's RX2 Advanced - I am also on the "recommend it" bandwagon.

I did the tests last week and it was amazing.

just 2 final questions about x form:

Now I have mastered the original mixes and again, employing the X-Form Procedure.

Maybe I am missing something but how do I go from 96 BPM to 98 BPM if there is no window like Time Shift and Sound shifter that let me retype the BPMs, instead of target length in time code?

I used TIME SHIFT just to calculate the target duration when audio is at 98 BPM ( 2.08% faster). ( I had to go from 3:54:756 to 3:49:765). So I trimmed the region with poly to 3:49:764.

Also, what does formant change at X-form processing?

Thanks
