ARGGHH!! Digital "pops" at the start/end of regions in Logic...

[44deluxe]

Hello slutz,

I have a G5 running Logic Pro 7 through a MOTU 828MkII.

It's pretty good in the main, except when it comes to cutting regions. Often when a region starts there is a glitch sound....the same at the end of a region.


If I glue regions together this normally fixes things but it's annoying...especially if you are trying to get clean precise loops to export.

Do any of you fine folks have any idea what I could do to sort this out???

It's nothing to do with your setup, it's just waveforms. You're getting 'glitches' because it's jumping from zero (or if you've got another clip in front of it, some random position) to the db level at start of the region... You either need to be fading in the region (a quick one will do) or cutting your regions on 0-points in the waveform (and that doesn't always work well). Usually a combination of the two is best. If you're mixing between regions, crossfade them a tiny amount. Even the tinest amount of crossfading can work sometimes.

Matt's on point. Some DAWs will autofade or auto crossfade (depending on their settings) and that often works well.

But if a waveform is cut in such a way that it has to 'jump' from -inf dB to a 'normal' signal level, you're going to get an audible glitch, as a rule.

Thanks guys...so I can use that little fade out tool at the start and end to fade in and out REALLY quickly to avoid that glitch sound right? thumbsup

btw...do those fades get saved when I export the audio?

Also use the "zero crossings" function when cutting audio.

Apply fades to audio regions by either using the fade tool or simply selecting the file(s) and punching in the fade time in the paramter box to the left on the screen.

Fades are non-destructive this way and will be included when bouncing a track. You can apply destructive fades by double-clicking the audio file and fading in the sample editor.

Thanks man, I'll go and investigate these options.


Great advice slutz. I appreciate the help.

But the only thing is if your having clicks on each region you wil go and manually apply a fade between each region on a track in pt. Because if you try to just copy the waveform you did a fade for some reason the fade changes.
