What is resampling

[Equilibrium]

I've always heard people talking about this, especially in DnB circles but I don't have a clue what it is. What is it and what does it do?

[C00kie]

Well, suppose you have a sample that's sampled at 44.1 kHz. If you convert it to 48kHz, then it is resampled (sampled again)

First it is oversampled, like you make a drawing by connecting the dots. Then the new values are taken from the lines.

Now what C00kie said is correct, but if you talking about what the dnb heads refer to, it's actually bouncing down a sample for further processing. It saves on processor power when you've got long effect chains, and some use as a creative option with countless resampling.

ah ok. So it's not about changing the sound as much as being an efficient, and processor friendly habit of production. Surely though some of the volume will be lost over time? is gain also a common process in "resampling".

Thanks for the responses

We're talking digital domain, so I guess, no, no volume will be lost; there could be a loss in sound quality though: imagine resampling a 44.1 khz (CD quality) track down to 8 kHz (bad quality), and then resampling back up to 44.1 kHz. What you lost in the first conversion (44.1 -> 8 kHz) will never be restored in the second (8 -> 44.1 kHz). May be a cool (lo-fi) effect though...

is gain also a common process in "resampling".

No, gain is just the process of multiplying the sample values with a certain amount. The sample rate stays the same, so there's no "resampling".

It is about changing the sound, as much you filter, distort, delay or whatever you're doing to your sample before you bounce it down. And then you do something else to it and repeat the procedure until you got something you like.

careful, altering and saving a file that has been filtered, delayed or distorted is NOT resampling. As stated before resampling implies that the sample rate has changed. The usage of this term in dnb stuff probably has a lot to do with the many time-stretching algorithms that employ resampling.

Are there any plugins (vst) that downsample and resample in real time (seems like a cewl way to create some digital sounding destortion tings...)?

Visit The Grid at Dogs On Acid and ask them what they mean by resampling and they will tell you the same thing as I have - if they don't simply tell you to do a search, as they have been asked that a lot.

Resampling may imply changing the sample rate, but it is not the only definition. And as far as the dnb community goes it is (more often than not) not the definition they use.

it is the only correct definition from a music or science or math standpoint. apparently "the grid" are none of the above..

To learn my definition, put a box of chocolates in front of me. See what happens the first minute, then what happens in each of the succeeding five minutes. Yup -- Lou Gossett, Junior. That's what I call resampling.

[Barbed Wire Kiss]

Definitions, like language (and music) are never static, and so can change. And many words in any dictionary will have more than one meaning. Since The Grid is about dnb (which is music) and the original question was about how it's used in dnb, then my definition is very much correct for this question.

I'm not questioning the original formal definition, it just doesn't answer the question set by Equilibrium.
