I can't really say I noticed anything notable, if anything at all, trying the plugin myself, certainly no decreasing of audio quality. Also even wikipedia calls the phenomenon aliasing, so the process against it would be called anti-aliasing.

With an equal or higher sampling rate, the resulting discrete-time sequence is said to be free of the distortion known as aliasing.' So I guess I was kind of on the right track in terms of it increasing sound quality in the way I described - kind of.

I did however discover the 'nyquist rate', which, according to Wikipedia 'specifies a sampling rate (.) equal to twice the highest frequency (bandwidth) of a given function or signal. Yeah, I'm just as clueless, but based on what I could find it does have something to do with sample rate. Actually I found some kind of documentation for LADSPA ( ) and now I know it does something called 'nyquist frequency modulation'. Or maybe someone confused the terminology again. Maybe it decreases the quality then? I certainly know there are some cool plugins like Bitcrusher that have similar purposes. The thing's called 'Aliasing' though, not 'Anti-aliasing'. But I've never heard of audio anti-aliasing either.

So I would assume that in this case anti-aliasing means an algorithm that calculates likely additional data points so it might be able to patch up some low quality, sharp sounding audio.

Similarly digital audio is basically a list of data points in sequence - the more per unit of time you have 'resolution', the smoother the waveforms will look. (The picture is confusing, everyone always mixes up the terms, so just ignore the words there)

Anti-Aliasing is a system to combat this effect, it calculates a way to smooth the egdes out. Unfortunately, depending on the amount resolution, this may look unpleasent with visible steps on diagonal lines for example. Since a screens resolution is not infinite or unspecific graphics will be converted into its grid of pixels. The common assocation here is with computer graphics, which are a great example. But I'm not quite sure.Īliasing is not a process, but a phenomenon, that occurs on digital technology, that doesn't have the unspecific quality of analog signals. I'm pretty sure anti-aliasing means making smooth, and so aliasing means making it more rough and chunky.

Most of these plug-ins have some sort of free vst workaround, but i am still curious about how to use the defaults properly. I have fiddled with the band levels, but it doesn't cut it when it has something like a drum kick in the modulator. Vocoder: It seems to have trouble playing the low end of anything.

Calf Envelope Filter LADSPA: It seems just flat out broken, since it just doesn't make any noise.

Declipper: Is it me or does it not do that?.

impulse converter: so apparently it's supposed to let you choose the reverb of a certain space (gross simplification but you get what i mean).

Aliasing: If the Wikipedia definition of aliasing has anything to do with this plug-in, it would mean it smooths out the sound.

Calf Analyzer LADSPA: It would seem like it is supposed to be some kind of visual analyzer, but i can't seem to find the display.

I'm not exactly new to LMMS and i know how to use a couple of the default plug-ins, but i have always been stumped by a couple of them that i just can't seem to figure out.
