How to create manually the glitch effect on guitars, vocals etc...

Hello and welcome to this week's article!

Today we're going to talk about a mixing topic which can be applied to any type of wave source and that, if used with parsimony, can become a powerful arrangement tool to make the track more interesting.
The "glitch" effect simulates a digital artifact of any kind (usualy the fast repetition in loop of a small soundbyte), and it's used widely in rock, pop, metal, hip hop and electronic music (for example it can be heard in the song Sex, Death and Money by Alice Cooper) as icing on the top of a cake which must already be good, to make it even better.

In order to make a glitch effect of repetition, which is the most common, you need to start with quantization, so take a small slice of the guitar track (or both if we're applying it to the rhythm ones), set the quantization to 32nds and just repeat the slice for i.e. a couple of measures (16 times, for example) and push play.

The sound will be the typical one of the reading error of a cd player, and this is just the basic version of this effect.
Now we can get creative: try to quantize slices twice as long to 16th of note (instead of 32nd) to see if they sound better, or create a rhytmical pattern, for example a 3 slice repetitions, 1 empty slice, other 3 repetitions and so on, and in this the limit is really just the imagination.

So far we have mentioned only taking one slice and repeating it, but if we have for example a riff of 4 chords, we can also simply REMOVE one or more slices, rhytmically, from the track, to create a "stutter effect", or use repetitively the same single slice per chord, or we can even change the quantization from one measure to another and move from 16ths of note to 32nds, to add even more movement.

Finally, it's time to talk about automations: with these, you can take your glitched section and automate on it one or more effects in order to give it even more character.
You can apply on it obviously any kind of effect, but our suggestion is to try one of these 2 (or both):

- a pitch shift, or tempo shift effect, that makes the pitch go down fast during for example the final part of the glitch.

- a bit crusher that goes from 0 to 100 during the glitch, to make it sound like it's deteriorating during the repetitions.

Let us know if you use other cool glitch effects!
