Pitch correction of 4 part singing harmony in single stereo audio track?

I have a stereo recording of a barbershop quartet. Someone previously spliced two sections together with the second section starting out at least a little flat. I’ve been asked to pitch correct this.

I’ve tried Variaudio and had some luck, but the results are tiny bit distorted. All I really want is a way to draw in a small pitch change to make a certain section of the audio track more sharp.

Ideas?

Thanks!

VariAudio works only on monophonic material.
For working on polyphonic material you’d need to obtain Melodyne (the expensive edition).

Ugh. There’s no way to just make a selection and increase the pitch by a few cents, same as it would work on a sampler? Just to be clear, I’m not trying to alter a single singing part in an audio track of mixed voices - rather, I’m trying to minutely pitch shift the whole track for just a little section (The whole singing group was a little flat, but in tune with each other in their flatness). Aren’t pitch shifting and time correction pretty basic features?

Maybe separate that part out from the rest of the track and use a pitch-shifting plugin on it? That would be shifting the whole track, not caring about individual parts within it. Then just bounce that part and do crossfades with the boundaries of the other parts of the track.

I don’t know if Cubase has a plugin like that built in, but there are plenty out there (e.g. Waves SoundShifter comes to mind), I think maybe even including some free ones.

Maybe instead of loading a plugin it would be sufficient to use the Fine-Tune value on the Info Line?
But this solution will shift a chord in a way that it might sound unnatural afterwards. However, if it is only a few cent it might work.

You have a few options

The direct offline process, envelope based pitch shift was exactly what I needed. Thank you, Grim!
