What is causing this click in the sound ?

Alright, i recorded a bass sound in wave.. then i made the recorded bass wave sample shorter..

And there is this click that comes at the end of it.

Here is an example, first 2 bars the original sound, the 2 last with the click.

I just cant understand why this click appears.

by looking at the sound wave, it's that small "drop" of the wave at the end of each bass sample. you just need to cut you bass sample where the sound wave's volume is very low.

this is your short sample with the click:


this is the sample without the click (I used SF to cut it) :


and this is how it sounds (old sample, new sample) :

it could be a problem with your vst programming...?! try and use the bassline with another vst and see if the problem appears then..

I'm inclined to agree with ronk. I think most quality editors have a "snap to zero crossing" option that will make sure your cuts occur when the waveform is at minimal amplitude as ronk has described. Is it possible the signal is clipped at all? I haven't looked at the file but I thought I'd toss that out as well just to make sure all your bases are covered.

Yes.. that works flawlessly.. thanks.. I still dont understand excactly whats causing the click though.. unexpected end of the wave ?

No, its not that.. ive already recorded the bass too a wave file, but its when i shortened the wave i got a click

exactly it clicks because you interrupt the waveform in the wrong point of its cycle. when editing audio material you should ALWAYS cut where the waveform meets the zero line, or else it will click. most audio editors have, as someone already mentioned, a "snap to zero crossing" feature that helps.

No that's not the case here. DC not matching, If they don't match then they'll cause a click. A bitch to get it sorted. The best you can do is to zoom in at max at the end of the file and make sure it ends at the zero line. The zero line is the absolute middle line in each channel. The higher the drop the louder the click. Cut the sample so it ends at the zero line. There are some VST plugins that can heal the sound from such issues. Can't give any names since I'm off my puter atm, but will be back home in about 90 minutes time gonna watch some telly at the place I am right now. Should be back at home around 10.30 pm gmt+1.

Just do a short fade in and out on the beginning and end of your wave file where the sound drops/stops.

The matter is pretty much resolved. thanks all.

i got that some time before... ( i use live ) and before the "freeze" funktion, that could appear when i bounced to wav.. however, if you record the wav into a loop sample, let the recoding loop like 2 times, and then undo the latest recording. this way you get a good looped sample that fits every time you multiply it...

Maybe it doesnt make any sense, but it was the best way i could describe it..

It's some kind of distortion. I don't really know what it's called though, but it happens when the derivative of the wave function is much higher than the rest of the wave.
