The room was measured with RoomEQWizard and it spits out a correction filter that I’ll need applied. Hopefully that will correct the behaviour I’m experiencing.Ĭreating a custom curve in the Equalization effect wouldn’t be nearly as precise as specifying the gain, q, and centre frequency of each band I want adjusted. I’ll try re-working the nyquist script that way. However - getting back to the purpose of your enquiry, why not just create a custom curve in the Equalization effect? (see: ) To write the code for applying gain to many frequency bands it would be better to create a loop rather than writing out lots of filters in long hand. Multiple “eq-band” commands can be applied simultaneously by nesting the commands, For example, to apply +3 dB at 1000 Hz, and -4 dB at 2000 Hz, each with a half gain band width of 0.5 octaves: (eq-band To make that command into a plug-in, you would add the appropriate headers (see: ), save the text as a file with a file extension of “.ny”, and then install the plug-in. Where “ track” is the selected audio in the track that is being processed, So, for example, if you wish to apply +3 dB gain to a frequency band that has a centre frequency of 1000 Hz and a half-gain width of 0.5 octaves, the command would be (Nyquist version 4 syntax) (eq-band *track* 1000 3.0 0.5) The basic Nyquist command for parametric equalization is: (eq-band signal hz gain width) See here for how to install Nyquist plug-ins: However, the standard and recommended way to run a Nyquist plug-in remains the same, and that is to install the plug. In Audacity 2.1.1 the Nyquist Prompt has been substantially upgraded so that it can now run full plug-ins. The Nyquist Prompt was originally designed as a quick and easy way to run short Nyquist commands.

The best way is probably to make a Nyquist plug-in that does what you want, and use that in the Chain. Am I correct in thinking the easiest method to complete this task is to set up multiple nyquist prompts (one for each filter) in a chain?
