Comments on: Time Stretching And Pitch Shifting of Audio Signals - An Overview http://www.dspdimension.com/admin/time-pitch-overview/ Advanced Signal Processing Tutorials & Software Sat, 05 Jul 2008 16:29:54 +0000 http://wordpress.org/?v=2.3.3 By: Bernsee http://www.dspdimension.com/admin/time-pitch-overview/#comment-368 Bernsee Wed, 30 Apr 2008 14:06:49 +0000 http://www.dspdimension.com/admin/time-pitch-overview/#comment-368 Thank you, I'm glad you like it. As a matter of fact, there is a Java version of smbPitchShift() available from the following web site: http://www.adetorres.com/keychanger/KeyChangerReadme.html I don't know why this link didn't make it on our news page, it must have been lost during the site redesign. Sorry for that. HTH, --smb Thank you, I’m glad you like it.

However, rather than implement this from scratch myself (fun though that would be), I have been trying to find an open-source java library that will handle realtime pit shifting and time stretching. It seems there arn't any which, given the public availability of the algorithms, I find very strange. Is there some fundamental limitation in the JavaSound API (the lack of an accurate enough clock maybe) that is preventing this being implemented in Java? Does anyone know of an (open-source) Java implementation of realtime pitch-shifting and time-stretching? An excellent overview.

May we suggest you post this question to our forum at http://www.surroundsfx.com/forum as there are a lof of pro sound engineers there who can help you with this kind of question in a more appropriate manner than it would be possible for us to do in just a reply to your comment here...

I also want to remaster it. I work with protools audiosuite TCE and Pitch shift plug ins. I´m wondering; * The protools user manual says about normalize the audio before processing. Would it be better to master it and normalize and then pitch shifting it? * My source material is the tracks from a CD. Would it be better for the processing to work in a session with a higher sample rate and bit depth? Hi,
