I programmed a Sytrus saw synth pattern to play a few notes along with automation clips that control the synth mixer track volume and the mix level of a low-pass filter in the signal processor chain. The instantaneous step change confuses the processor very briefly, and you hear a crackle. The same concept of infinite slope applies for automation clips and plugin envelopes. All that’s left to do now is to replace all of the instances of your old sample with the declicked one in either your Playlist or Step sequencer/ Piano roll. You can either click and drag the “Drag/copy sample/selection” button to your Channel rack, or just click the “Send to playlist as audio clip/to channel” button to send it to the Playlist as audio. Deselect your declicked sample clip by double-clicking anywhere in the Edison window. Now we need to replace the old sample with the declicked one. Here’s what the declicked FX Blackhole sample sounds like: We want to slope just enough to get rid of the clicking without excessively modifying the attack time. This will end up making it sound too different from the original. It’s important that we don’t declick too much of the sample.
We can see the sample starts at zero now and gradually slopes up. In Edison, zoom in close to the beginning, select a few cycles of the sample waveform, and then hit the “Fade in/declick in” button on the top toolbar in your Edison window. Once you have Edison open, navigate to your Channel rack or Playlist and click and drag the faulty sample into Edison.

How to Declick a Sampleįirst, go to your Mixer, select a random Mixer track, and add Edison to the processor chain. To fix this, we need to declick the sample, which just means we’ll make our sample start at zero volume. This results in an infinite slope and some crackling. We can see at the very beginning, on the left-hand side, the sample starts at a non-zero value in the middle of a peak in the waveform. Now lets zoom in very close on the beginning of the sample waveform and see what’s going on. Now lets see what it actually looks like in Edison.Īt this level of zoom, everything looks normal and fine. We can hear the blood-curdling pop at the beginning as a result of the poor editing I did. This creates a slope of infinity in the volume parameter and gives your computer’s processor a brain freeze, resulting in a pop, blip, click, or crackle at that point in time.įor this example, I took a stock FL Studio SFX sample called FX Blackhole and edited it in Edison so that it no longer starts at zero volume. With samples, you will experience this glitch when the sample volume starts at a non-zero value and goes from zero to non-zero instantaneously. Once you determine which one it is, you can remedy the problem accordingly. It sounds like Megatron dumping Rice Krispies into a jet engine, and it can happen throughout the entire track if the buffer is set very low, or just for the parts that have a lot going on if the buffer size is decent, but just not enough.
If it’s caused by the buffer underrun situation, it’s pretty easy to identify. If it’s caused by a very fast change somewhere in your mix, you can pinpoint where the problem is by simply playing your track and looking for samples, automation clips, or plugin envelopes at those points in time at which you’re hearing the glitch. They are commonly (but not always) due to poorly edited samples or poorly designed automation clips and plugin envelopes. An extremely fast change in the value of an active parameter in FL Studio.What Causes Crackling and Popping?īlips, pops, clicks, and crackles are caused by two things that are overloading your computers processor:
They’re relatively easy to understand and fix in FL Studio, and this quick tutorial will show you how. As irritating as they are though, you will not need to invade a country to fix them. They lay hidden and silent in the mix, striking with explosive and unexpected fury to decimate the eardrums of anyone unfortunate enough to hear them. How to Fix Blips, Pops, Clicks, and Crackling in FL Studioīlips, pops, clicks, and crackling are the terrorists of the music production world.
