In Nyquist, as with List, there are two types of numbers – Integers and Floating Point numbers. An integer is a whole number with no decimal part, such as 1, 2, 99, 1000000. A floating point number is referred to as a FLONUM, or simply a “float” (floating point number) and is most easily defined … Continue reading Floats and Integers
Nyquist contains a function “ENV” (envelope) that is a special form of the pwl (piece-wise linear envelope) which is very useful when synthesizing sounds. There is a good description of the Envelope function and how to use it in the Nyquist manual. It works in a similar manner to the traditional ADSR envelope that is … Continue reading Fix for bug in “Envelope” function.
This plug-in allows the left and right channels of stereo tracks to be mixed and distributed between the channels of a stereo track. Examples: Mix left and right channels in equal proportion to produce a 2 channel mono track. Invert left or right channel independently of the other. Mix each channel with the other channel … Continue reading Channel Mixer Plug-in
So you’ve used a few plug-ins in Audacity and you’ve heard that it’s possible (and not too difficult) to write your own plug-ins. Now what? Where do you start? Here’s some pointers that will hopefully get you on your way. First, three pages from the official Audacity web site: http://audacity.sourceforge.net/help/nyquist http://audacity.sourceforge.net/help/nyquist2 http://audacity.sourceforge.net/help/nyquist3 After that, an … Continue reading Getting Started with Nyquist
Nyquist can produce tones that are accurate to the exact number of samples required. For example, if you want to generate 441 samples of a 1kHz sine tone, you can use the following code in the “Nyquist Prompt” effect: [cc lang=”lisp”] (setq num 441) (abs-env (sustain (/ num *sound-srate*)(hzosc 1000))) [/cc]
A couple of simple but useful functions. Hopefully this will save someone several hours of scouring Google. To test the code, copy and paste it into the Nyquist Prompt effect and press the DEBUG button to see the output. [cc lang=”lisp”] ; function to convert a number to a string (defun number-to-string (number) (format nil … Continue reading Converting numbers to strings and strings to lists
