Well it’s been quite some time since my last post here, but now we’re back 🙂 So what have I been doing all this time? Other than being locked down in the Covid-19 pandemic, I’ve mostly, working on Audacity, providing technical support, writing cool new plug-ins, and making music. There have been several updates to … Continue reading AudioNyq is back!
There are many reasons why we may want Nyquist to know the current date or time. We may want to add the date to an exported file name, or we may want to measure how long it takes for a plug-in to run. In Nyquist 3.16 we can do this with (get-real-time). For timing a … Continue reading Get Time Now
This is an experimental “proof of concept” plug-in for FM encoding and decoding. It was written as a bit of fun for the Audacity community – a competition in September 2016 for Audacity users, developers and support crew. The plugin can be download here: Installation Instructions: For the current version of Audacity, please see HERE … Continue reading FM Encoder Decoder
What are crossover filters? Due to mechanical / physical constraints it is near impossible for a single speaker cone to accurately reproduce the full audio range. Carefully designed small speakers may work adequately for low power use such as portable radios, but for larger, higher power and higher sound quality speakers, multiple “driver” units are … Continue reading Three band crossover filter (part 1)
*Scratch* is a very useful Nyquist variable (in Audacity). It has the unique property that it survives from one call of Nyquist to the next. This allows, for example, a plug-in to perform sequential operations on a series of tracks, or for one plug-in to analyse a track and then another plug-in to process the … Continue reading *SCRATCH* – the variable that lasts
This is a short tutorial about generating sounds and shaping the sound with an envelope. Nyquist includes a number of oscillators and other simple sound generators that may be used as building blocks. In this tutorial we will be using the triangle waveform oscillator as the basis of a simple piano-like “ding” sound.We’ll start with … Continue reading Synthesizing musical notes
When calling a function we commonly pass one or more parameters to that function. In most cases these are simple variables; integers or floats, but could be lists or arrays. In the case of passing arrays there is a hidden danger. Let’s consider a simple function:
|
1 2 3 |
(defun product (x y) (* x y)) |
To use this function we pass two values, … Continue reading Arrays as function arguments
I’m very pleased to announce the release of an update to Isochronic Modulator. “IsoMod 2” has all of the features of the original effect, with the addition of alternative pulse shapes. Right click to save : isomod2 (For Internet Explorer “Save Target As”)
Audacity has a “Change Speed” effect, but it is only accurate to three decimal places. For greater accuracy a short Nyquist script can be used in the Nyquist Prompt effect. In this example the length of the selected audio was 599.999 seconds and I wanted to stretch it to 600 seconds duration.The durations may be … Continue reading Changing the speed and length very accurately
A “peak limiter” is a kind of dynamic range compression effect that “pushes down” on peaks so as to reduce their level. Unlike other compressor effects, limiters have little or no effect on the surrounding audio (except for a few milliseconds either side of the peak). They are particularly useful for reducing “transients” (very short loud … Continue reading Peak Limiter
