Audacity Forum

Is there any high quality pitch (without speed) changer plugin or method? I tried using Audacity's internal pitch changer, it did the job, but unfortunately the resulting audio sounded like it had previously a low bitrate (the source audio is quite high in quality). I am using Audacity unstable 1.3.6 Unicode on Windows

Yes... upgrade to Audacity 1.3.7. It includes an effect called "Sliding Time Scale/Pitch Shift", which uses SBSMS by Clayton Otey. It's slow, but the results are much better than what's available in 1.3.6. (The old effects are still there for when you need speed rather than quality.) --Allen

Thank you for the reply. I tried that one, and I've found out that it also adds that strange 'echo' effect to the sound which I don't like, so, are there any other suggestions?

I don't know of anything else for Audacity, though there might be something out there. Beyond Audacity, you might check out this Wikipedia page: http://en.wikipedia.org/wiki/Audio_time ... dification. It talks about the different approaches to doing this, and at the bottom are several software links. --Allen
