Audacity includes a wide range of built-in effects, but surprisingly there is no distortion effect. Time to remedy that… Here is a simple distortion effect with 10 types of distortion. Each preset modifies the shape of the waveform in its own particular way. There is also a slider control to set the amount, or “drive”. … Continue reading Distortion Effect
It’s incredible that an article can be written about what options are available when XP is dead and buried, with not a single mention of other operating systems, but that is exactly what is happening in much of the mainstream press. I’m not suggesting that the likes of computerweekly are getting backhanders from Microsoft, but … Continue reading Windows XP end of support: What to do next
It is a common misconception that Audacity’s Nyquist plug-ins must be slow because they are written in an interpreted programming Language. Nyquist is an interpreted language, meaning that it runs directly from the code rather than being compiled first, but the inner loops of many DSP functions are pre-compiled in highly optimised compiled C code. … Continue reading Are Nyquist Plug-ins slow? (Compiled vs Interpreted languages)
For a shorter display when hours [or hh:mm] are not required, set the ‘short’ parameter to 1. To display hh:mm:ss without milliseconds, set the second parameter [places] to 0. The ’round’ parameter can be set to round up, round down or round to the closest whole number of seconds. For full details of all options, … Continue reading Display time as hh:mm:ss
This little plug-in is a bit of fun. It is a distortion plug-in effect that simulates a kazoo. To use it, record yourself humming, then apply the effect. Some interesting sounds can be made by applying the effect to other sounds, such as guitar or keyboard recordings. Right click to save kazoo.ny (For Internet Explorer … Continue reading Kazoo Effect
This was one of my first attempts at modifying a Nyquist plug-in (so please don’t expect good coding style 🙂 Someone asked me about how to fix some badly clipped audio. Repairing clipped audio is bad enough at any time, but in this case the problem was exacerbated because not only were some of the … Continue reading Clipfix mod
A common problem for people that are new to Nyquist is how to modify audio samples, for example, to set certain sample values to zero (silence). The temptation may be to read the audio sample by sample and modify them as necessary. In the vast majority of cases this is NOT the best approach as … Continue reading Silence part of an audio track (part 1)
This code snippet use SND-COMPOSE to create a vibrato effect
The basic detection method is just one short line of code: What this does is to fetch consecutive samples from the sound *track* until a sample is returned with a non-zero value. A word of caution, SND-FETCH is destructive to the audio data. If *track* will be required later in the code, use SND-COPY to … Continue reading How to detect a sound in just a few lines of code
A newline, also known as a line break or end-of-line (EOL) marker, is a special character or sequence of characters signifying the end of a line of text. The actual codes representing a newline vary across operating systems, which can be a problem when exchanging text files between systems with different newline representations. Windows uses … Continue reading New Line CR+LF
