Creating loops from audio and avoiding the "pops'

I use Cubase SL 3 mainly as a song writing tool. I will often play a bass part one time, then cut it and copy/paste that segnment until satisfied.

I run into problems when the loops end and start at different volume levels. This problem often results in a "pop" or "click" when transitioning from one loop to the next upon playback.

Is there any special kind of functionality in Cubase, or any other tool for that matter, that will eliminate this "pop" sound and smooth out the transition between my looped segments?

If there's another way to go about doing this, please let me know.

Thanks in advance.
 
jep, simple solution,

select Loop 1 and Loop 2
then press X

X is the shortcut for Crossfade, when you use a crossfade between two wave files you make sure the transistion is smooth and there won't be clipping,
if you don't wanna use crossfades you gotto make sure you cut your samples at a zero crossing, but believe me , Xfades are easier :)

after you selected the tracks, pressed X, you'll see that there's this....kinda fade in and fade out betweeon the two tracks, you can make the Xfade longer or shorter by just clicking and dragging it, if you select the Xfade you can also delete it, its all non destructive so won't harm your original audio files,
(in case you didn't know, select a Loop, press CTRL+D , thats the shortcut for duplicate, is faster than copy:paste :))


this should help you out,
peace
 
that's exactly what i needed to know.

thank you so much!
 
Or zoom in on the beginning and end of the section to be looped and make your cuts at zero crossings.
 
Im not sure about Cubase, but I get em when cutting and pasting clips in Sonar 4. As mentioned earlier, the very beginning and ending of your clip needs to be at zero, else POP!.

Crossfades wont work unless the clips overlap. I generally load the WAV into WavLab and apply an extremely short "easy fade" (1 to 2 ms) at the ends of the clip. Works every time and is audibly undetectable.

I'm sure that there is a way to do this inside Sonar but I havent figured out how yet. WaveLab works great.
 
In Cubase, there is a button (in the sample/audio editor) and a menu choice in the project/arrangement window for selecting "zero-crossing". Make sure to enable that. Once it's enabled, all your cuts will fall on the zero-crossing points, which should eliminate the pops and clicks that you experience. If it doesn't then combine that with earworm's advice.
 
I wonder if Sonar has something like that. Thanks, I'll hafta check.
 
i suggest you do a real quick search in the help file of sonar (press F11 i assume) (or any other app) , search for "zero crossing",
allmost EVERY audio editing app i used has the option 'snap to zero crossings' (or something similar)
indeed, if you can check the option that you allways snap to zero crossings then you have less chanse that Clicks will appear...

any kind of fade out, crossfade does the same thing, if i'm correct then i'd describe a zero crossing as "SILENCE" , or 0 volt, mix no sound with no sound and you can't have a click
