An alternative way to condition the signal would be to apply a "noise gate" (such as: http://wiki.audacityteam.org/wiki/Nyquist_Effect_Plug-ins#Noise_Gate) and then quantize the signal in the new plug-in code (http://www.cs.cmu.edu/~rbd/doc/nyquist/part8.html#index541). Example (this creat...

From a quick test, the limit appears to be a little over 1 million samples. Much more than that and Nyquist will crash, which will probably take Audacity down with it.

First I'd suggest normalizing the signals to 0 dB ("Normalize" effect). This makes the signals easier to work with. http://manual.audacityteam.org/o/man/normalize.html If you want to batch process a lot of files, you can add the Normalize effect and your new Nyquist plug-in to a Chain. htt...

It is by design that the Nyquist version places the label at a prescribed period before the end of the silence (not in the center of the silence).

You can disable the Metadata from opening on Export in Preferences:
"Edit menu > Preferences > Import/Export: Show Metadata Editor prior to export step"

Look in the Recording tab of the Windows Sound Control Panel and ensure that the device is set to 2 channel recording - you may need to also turn down the recording level very low (Windows often thinks that these devices are mono microphones).

Please post a short sample recording in WAV or Flac format so that we can see what you are working with. See here for how to post an audio sample: http://forum.audacityteam.org/viewtopic ... 49&t=64936

It is the same small group of volunteers that contribute their time helping other users on all boards of this Audacity forum.

Nyquist cannot (yet) access Audacity's built-in effects or other plug-ins, so to fade in/out an effect in one track you would need to write the effect as a Nyquist effect, or modify an existing Nyquist effect. How complex that task is depends on the effect. In some cases it can be simple, for exampl...

No it's not. You can find out about Audacity here: http://web.audacityteam.org/about/features

No it does not work with either model.
