Timestretch Torture Test

[chamelion]

OK. I admit it. I'm completely blown away by Melodyne 3.

After reading through a forum discussing Pitch In Time and the horrors of clients demanding timing changes after the event, particularly with vocals, I decided to run a test. The original tempo was 118.3bpm. I stretched it to 108bpm, and then right down to 80bpm. Crazy.

I'm not suggesting for a moment that you'd go to these ridiculous extremes in the real world. It's just a torture test - and the results are pretty impressive. I've found the kind of marginal time-stretching that crops up in the real world to be transparent, seamless, and artifact-free with M3.

Geoff:

Correct me if I'm wrong...

Melodyne will not do a satisfactory pitch shift on a stereo mix or polyphonic material right?

In other words, transpose an existing mix or, say, a piano track up or down a whole step?

I'm still looking for the "Holy Grail" of pitch shifting software...both here and at other studios, I've tried Waves "Sound Shifter", "Pitch 'n Time", DP's own built in pitch shift (both DSP and standard) and Sound Toys' "Speed".

They generally work well with a thick "pop" song, but tend to fail with softer orchestral passages or songs with soft interludes (artifacts become very noticeable)

Last attempt was transposing 2 mono acoustic guitar tracks and a stereo electric guitar up a whole step. We used both Pitch 'n Time and Sound Shifter...the results were "acceptable" but not as if the player had actually played the song in the higher key. (some digital noise and, for lack of a better term, some digital "flanging" when the acoustics were strumming full chords...in this case Sound Shifter was slightly better )

Thanks!

That's right. It pitch changes as promised, but formants are disabled - which pretty much defeats the purpose. Having said that, I've had some quite acceptable results pitch changing individual chords wiithin a rhythm guitar loop. Also, I think I remember hearing some chords among the Liquid Guitar demos on the Ueberschall site. I'll know in a couple of weeks when stock is available here in Australia and my copy arrives

In the meantime, I hope the Celemony team is sorting out the formant trick.

To obtain the kind of results in the torture test example, do I need to buy Melodyne 3 Studio or Melodyne 3 Cre8? Thanks!

As I understand it, the only difference between M3 and M3 Cre8 is that M3 supports polyphony and Cre8 is mono. You can see a product comparison here: http://www.celemony.com/cms/index.php?id=m3_comparison

Thanks for that link Geoff. Melodyne 3 will be my next purchase. The company should definitely hire you!

Also....

From the Melodyne 3 Manual;

With Melodyne, you can open and edit audio files in the following formats:
••“ WAV, AIFF, SND or Sound Designer II (the latter only on the Mac)
••“ 8- to 24-bit (Melodyne cre8) or to 32-bit (Melodyne studio) resolution sampling
rates of 22.05,44.1,48, 88.2 or 96 kHz (Melodyne cre8) and 192kHz
(Melodyne studio)
••“ mono or stereo

I have been playing around with Melodyne Studio 3 a bit (having used 2.6
in the past). Truly amazing application.
