Default Audio clipping after stretch marking

Hi there guys!

I always use the stretch marker technique to quantize my my drums after recording it. I have pretty hot signal coming into my tracks, essentially Kick and Snare, but it never clips. I have a good enough performance playing very close to the metronome, but I like to quantize it.

After use dynamic split to create the stretch markers at the transients I always use the option "snap to grid" to get it in right tempo, but it also make these tracks starts to clip.

I know that when you use that you stretch or shrink the audio destroying its original waveform, but I don't think it has enough "power" to clip a signal that originally doesn't...

Any of you experienced some like it?

Thanks a lot guys!

There’s no good reason it wouldn’t, if the peaks are already close. While it’s not exactly the same thing, when we encode mp3s that peak near 0dbFS, we sometimes end up with peaks 2 or 3 dB over. Reasampling of any sort can and should be expected to make some peaks higher. If you’re limiting or clipping to maintain a predictable ceiling, you must do that after any of that. Of course you can’t with mp3, but in this case you were probably going to do some of that anyway, so...

I still thinking what happened to have this behaviour, but I "solved" it decreasing the output level of those tracks. It's a workaround for now but it's kinda strange.

The original signal after processing doesn't clip!
The original signal after processing stretched to match the song tempo clips!
