Limitations via effects

First of all thank you for this software. I’ve used it many-a year. I’m 22, going into radio production, and on the side I make music, and have found audacity aspite all others to be the most user friendly of the music software industry. On an older version of audacity I remember you could go over the limitations of hz/other aspects of the effects i.e. beyond the table: you could input manually say…9999hz on tremolo with a 50% wet level at a saw wave… and this would be a form of very smooth distortion with an added extratone-esque like sound… but now it seems the newer versions of audacity have prevented this feature because when I make an input they do not let me go over certain amounts, and I’m now limited to ten hz… “value not in range” it says… is there a fix to this? Is it because I’m using windows ten, or should I downgrade a version?

Yes input is now validated for consistency so you cannot enter values outside a slider value.

The next 2.1.2 release of Audacity will let Nyquist plugins (where appropriate) use a text box without slider that does not have any practical range limit. However Tremolo itself will not be changed for 2.1.2.

If you want to change the ranges that are validated, open the tremolo.ny file in Audacity’s Plug-Ins folder in your favourite text editor. For example you could change:

;control lfo "Frequency (Hz)" real "" 4 0 10


;control lfo "Frequency (Hz)" real "" 4 0 10000



At such a high frequency it’s really not a “tremolo” effect any more, but rather an “Amplitude Modulation (AM)” effect.
There are some other modulation effects that you may find interesting here:
(Download and installation instructions:

I notice that there is not an “AM” modulator effect there (and the “Ring Modulator” could do with some improvements). If you would be interested in a purpose made AM modulator (rather than just abusing the Tremolo effect :wink:) feel free to request one in this part of the forum:
I think that a good AM effect would be a nice addition.

Thank you for the suggestions, I will look into am, and ring modulation, I will be looking forward to 2.1.2 since there will be less limitations, and then I could abuse tremolo AND A.M. and Ring-mod to my hearts content, I also looked into the situation and second the motion for an option prompt like “continue anyway?”. Have a good one.

You can abuse them to your hearts content in Audacity 2.1.1 :stuck_out_tongue:
One really nice thing about Nyquist plug-ins is that they can be modified very easily using no more than a plain text editor (NotePad++ is recommended, but plain old “NotePad” will do). Nyquist “.NY” files are just “plain text” with the usual “.TXT” extension changed to “.NY” (See here for how to show the file extension;

Near the top of the .NY file are “headers” that begin with a single semicolon. The semicolon tells Nyquist to ignore the line, but Audacity is able to read them. When Audacity sees a correctly formed line beginning with ;control Audacity will create a control such as a slider widget, a text widget, a multi-choice widget…
For Slider widgets, there are three numbers at the end of the ';control" line which set the default, minimum and maximum values respectively. See here for more information about ;control widgets:

After modifying a Nyquist plug-in, ensure that it has the required “.NY” file extension (if you use “NotePad”, the file extension may be changed to “.TXT”, in which case you would need to rename it back to “.NY”)

If you have any questions about modifying Nyquist plug-ins. please ask on the Nyquist board of this forum:
