Pitch Shift

Pitch Shift

hey all. this is a question for all who mess with pitch shifting. everything
i make has really bad artifacts in it. i’m trying to make one track that has
some Good ( doesn’t really have to be great) lowered vocals. ( i don’t
really have a low voice and i think it will add to the song) this is hip hop
of sorts so it doesn’t have to be terribly in tune to sound good. i just
don’t want the tinkles. have any of you messed with this? have anything you
would be willing to show me? or perhaps a link to a good shifter? (
MadShifta isn’t good enough for what i want). Oh and at most it only has to
go down about a major third to get what i want. just no tinkles :)

anyway, any help or suggestions would be greatly appreciated :)

oh and it has been brought to my attention that i am a bad poster in that i
never say thanks for the info. so i would like to take this time to thank
everyone for any advice or help that i have ever gotten on this forum! THANK
YOU :)

If you can handle a little latency, don’t overlook gizmo~.

Seconded, I find gizmo~ very good usually.

And if you can’t, you can improve the quality by FFT convolving the
original with the pitchshifted one to super impose the formants of the
original on the shifted version. Tends to work better on material
that has been pitchshifted upwards. Not as good as gizmo~, but can be
faster.

Also, consider using a high-shelf filter on the pitchshifted output to
reduce the prominence of artifacts. (alternatively, you could use a
multiband compressor)

good idea but the thing with cutting out the highs is that i do want some
highs in the vox or it will not sound as alive.
i’m gona mess with gizmo~ some more ( just got home from work) and this is
just for production so latency is fine :)

i remember why i don’t like gizmo~ all that much. it’s exactly like
Madshifta. it makes the “chuuck chuuck” noise with any kind of percussive
noise your mouth might make. same thing it does with drums :( you guys know
what im talking about? the chuuck chuuck

If you are on OS X, Spear is a great program for pitch shifting. It’s an fft style process but when you get the settings right It is as simple as a drag to the new transposition level.
