Java Sound "Time Stretching" pitch shifter?

I am NOT a pro DSP person, and have seen past debates, so to clarify,
just looking to develop a simple component to integrate in a Java
program that can adjust the PLAYBACK SPEED WIHOUT affecting the PITCH.

If you use Windows Media Player then you can see an example of such a
simple component
1)Go to the VIEW menu
2)Go to ENHANCEMENTS
3)Choose Play Speed Settings

or
http://www.dspdimension.com/html/timepitch.html#compare
Shows the original file, and 200% time stretched, which is what I'd
like to do.

Have found some links at:
http://www.dspdimension.com/start.html

for a JMF pitch shifter, but the link doesn't work for the stuff by
Andrew De Torres


Am learning Java, and find it odd that finding a pitch shifter is so
difficult..could immediately find FREE ones available for various
other langauges, but not java.

Have found an old book by Craig Lindley, which includes the source for
a pitch shifter.

But before going to buy an old book, with possibly outdated source
code... just wondering if there is anything like this available, or a
TUTORIAL on this specific aspect of DSP

I am learning JAVA, and after taking a look at that DSP site, it seems
that unless I was career orienting myself for DSP it would take awhile
to make a simple comoponent.

Thank you

Hi Mike,

I know of someone else who is working on a Java port of the SMB pitch 
shift code, I also have the email of Andrew Torres who might be able to 
help you (he doesn't have a new web site up that hosts his code, which 
is why the link doesn't work).

Email me off the list for more details: smb [at] dspdimension [dot] com.

Just for the record, Andrew's Java port of my DSPdimension pitch shift 
code (a.k.a. "KeyChanger") is now at:

Hello, 
I'm interested in this subject, too, but the link doesn't work any longer.
Perhaps there is another link? 

Thanks, Helmut

The thread is over four years old and Stephan Bernsee hasn't posted
here for a couple of years. You might have better luck sending him a
mail directly.

Hi all,

I saved a copy of the code here: http://stephan.bernsee.com/DeTorres.zip

It is also available via archive.org. I do not know the whereabouts of
Andrew DeTorres but his web site went down a couple of years ago.

Hope this helps
Stephan
