Nyquist error value

Programming and Development Nyquist
1

Hi, I have a problem with using certain plugins in audacity. The one I’m trying to use is called Turntable Warp (.ny)…
However, whenever I try to use it, there always seems to be a different message that reads:

“Nyquist returned the value:”

And a value number that changes every time I select a different part of the audio file like:

Nyquist returned the value: 85.100207
Nyquist returned the value: 137.600867
Nyquist returned the value: 326.612438

So, what is wrong? Or if that plugin is no good, where can I find one that does a progressive speed change (like an old gramophone loosing speed)?
The plugin is installed in the Audacity folder where the plug-ins are at… I also have a folder that says Nyquist that I can’t remember how I got it there or if it was already installed…

Thank you for all your help!! =P

PS: I have NO experience with coding nor any programming of any sort, I’m just a regular user that want’s to edit their music to make a great video or something with that music…

This must be a bug in the plugin. The “Nyquist returned the value: …” message appears if a Nyquist plugin returns a number instead of a sound (what must be a bug in the plugin). Can you give a download link where you got this plugin from? (there are several “Turntable Warp” versions floating around…)

Maybe using the built-in “Sliding Time Scale / Pitch Shift” in the Audacity_1.3.13-beta “Effect” menu or the Audacity Time Track ?

The version available from here should work: http://wiki.audacityteam.org/wiki/Nyquist_Effect_Plug-ins#Turntable_Warping_MS

Well I got it from here: http://audacity.238276.n2.nabble.com/Progessive-speed-change-td243665.html
Which in return gave me this other link (the actual download site): http://audacityteam.org/download/nyquistplugins

Yeah, that was what I was looking for as well, thank you!!

It works perfectly and does what I was expecting to do!! Thank you!!!

There are two versions of turntablewarp available from that page. turntablewarp.ny is for mono tracks only - I suspect that this is the version you downloaded first. If applied to a stereo track it will return a numerical value rather than returning a sound.
The other version is turntablewarp-ms.ny which works on both mono and stereo tracks (hence the “ms” in the name).
