How to edit out popping noise at the beginning of loops?

Hi, a lot of times at the beginning of a loop, there is a real loud "pop" noise on the first kick drum. I was wondering if there was some way to get rid of this with perhaps Sound Forge?

occurs when you start on a peak or trough, if you can, adjust the sample back a bit so your not on a peak or trough, you can do this by moving forward but you might take the attack dynamics out and loose the punch.

If you can't adjust it as above then add a small amount of attack, again be carefull not to loose the punch, it dosn't take much

and you can do this in any waveform editor, what programes are you using?

I use fruityloops, acid, and soundforge.

I think you can do it in FL, though not really used so not sure. From what I remeber you can open the sample (i guesse your using samples?) into the window (usually defaulted on the right) where it alows you to add effects etc (you follow?) in there you will be able to adjust the amp envelope, add attack untill the pop stops.


Alternativley, and a much better idea, use a different sample. Thing is that if the sample aint right don't use it, most important thing is using the right samples (trust I learnt this hardway and spent many hours fuking around with samples, this time is better spent finding better samples.)

Or put a tiny fade-in at the start of the sample. I think Live does this by default. You should def be able to do it with Soundforge. But as eLBe said you can try and start the sample on a low value - there might be a 'snap-to-zero' option in Soundforge as well.

make a slight fade at the beginning and end of the loop

you can do this so you eliminate the pop, but not change the loop time

Cut ONLY at zero crossings.

Or call these guys, but expect some dubious pretentious rhyming artifacts to be introduced.

Cutting only at zero-crossings is cool, but some complex waveforms have zero crossings spread way far apart. A really tiny fade in at the front is what I do to all my samples. I mean like just a few milliseconds. It's not noticeable. Fade out on the end of the samples is useful too. I also do DC offset removal on my samples too.

I must admit I get lazy doing the fade ins and fade outs on completed songs so much of the time I just add a second of silence before and after the song start. --Not track gap, but actual silence.

The silence at the beginning of a track can be useful because sometimes online streamers glitch out during the first second of a track while it's buffer loads and the track begins to play. Also, some boombox CD players automatically fade in at the beginning of track playing. It's an annoying feature because if your track starts right away, then you lose the audibility of the first sound of the track.

I realise that the extra silence at the beginning of a track can be annoying to some DJ's trying to create seamless playback sets... so not everyone will want to do this. For some songs, as an alternative, I will put an extra measure of music before the track starts. Usually it will be some kind of non-essential sound effect like a reverse cymbal or some kind of ambience.

Moving the start point around untill it doesn't click works most times.
So does the little fade. But sometimes you have to fade too far and you loose some snap in your kick. If neither of these work and you're still getting click try the Waves bundle. There are 4 preetty sweet little tools.

X-hum
X-noise
X-click
and something else I forgot....

Just a frequncy specific compressor that only hits the desired frequency.
Pretty useful shit.

Waves Trans-X transient shaper is probably the one you are thinking of.
