Step 2 install the plugin Go through the installation process but only to the point where it asks you to specify the installation folder. (the three numbers at the end of the line are, default value, minimum value, maximum value. Step 1 download the correct version of the plugin Based on the fact that we need the 32-bit version to play nicely with Audacity, that’s the one we’ll download for this installation.

So, here are the best VST plugins for Audacity. It also has its charm, and some would say, workflow benefits. If you still want to be able to set the threshold level to at least -40 dB There is no denying that Audacity has its limitations, but support for various types of plugins (VST, AU, LV2, etc.) is not one of them.

Apply Limiter with: Input gain = 5 dB, Limit to = -10 dB, Make-up gain = Yes.Normalize the track to 0 dB (so the maximum peak is now 0 dB).So, for example, if to apply 30 dB reduction in dynamic range, you can: Note that 20 dB reduction in dynamic range is a huge amount, and attempting to reduce the dynamic range even more is likely to introduce significant harmonic distortion (though this may not be a problem for a thunderstorm recording). If you need even more dynamic range compression than that, you can repeat the effect (Ctrl + R). In the latest version, (I don’t know which version you have), you can get an effective minimum threshold of -20 dB by setting the “input gain” to +10 dB (amplifies the signal by +10 dB before limiting), and the “Limit to:” threshold to -10 dB. The latest version of the Limiter plug-in is included in the current version of Audacity.
