Brian,

Thanks very much for that mini-tutorial on the pitch stretch. This is the 
one called "Cakewalk Time/Pitch Stretch 2" in the Process/audio Effects 
menu?

Dave

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,
Jvrgen 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.
