Sound Forge's algorithms for time and pitch stretch are ancient when compared
to the MPEX and Radius algorithms in Sonar. In Sonar, you can stretch or
compress by over 50% without hearing hardly any artifacts. The pitch change can
transpose entire segments of music by many semitones while preserving the
formant, so the music doesn't sound like its just a sped up tape. If you're
working with a solo instrument or voice, you can stretch time and shift pitch
even further with great results.
For a destructive pitch change, you can actually use the transpose command in
the process menu on an audio track, just like you would with MIDI.
Time stretching is best done by using audiosnap. Once you convert a basic audio
clip in to an audiosnap clip, you can stretch the clip to a certain length,
stretch the clip so that it finishes at a specific time in your project, cause
it to automatically expand and collapse as you change the tempo of your
project, and more. All of those changes are performed in real time, and are
non-destructive, so you can edit the length and other settings as many times as
you need to to make sure all is well before you export your project. Have a
look at the CT tutorial. There is an entire section devoted to audiosnap.

I have used the pitch change in soundforge and it seems to work okay, although
you can definitely hear a change. If I were to use this feature in Sonar, I
assume I would use it after creating the audio track and before exporting it to
a waive. Is this correct? By the way, I'm using sonar 6 producer.

Hi there, Luis and omar.
I must tell you, I love that feature in sonar and I find it very good
my self.
I did some pitching for a client one night or better said, not a
client, just a good friend of mine cause she wanted to sing some songs that was
a little bit too high for her.
so, I tested that function of the time stretch/pitch shifter in sonar,
and it worked out really really good. and the vocals she sang was perfect for
that song.
Regards,
Jörgen Hansson!

i think 3 semitones up and down is acceptable. depends on the
quality you need , if it is for a demo it's fine.
it takes some time for processing so you can select a small
fragment and process as a test and once you find the right setting you can
process the whole song.

I've never used it before. Would I be able to change it
to just about any scale I needed to?

the time pitch stretch that comes with sonar
works very good.

Hello,
I may need to change the pitch/scale on
an mp3 instrumental for a client to fit their vocal range. Do I have more
options to achieve this in sonar or soundforge?
Thanks.
