Hi everyone,

Anyone know how to apply a filter,say reverb or pitch change to a specific region of a clip without audible glitches at the beginning and end of the region. Eg. o to 30 seconds of a clip is ok 31 to 40 seconds is flat in pitch 41 to end of clip is ok so I only want to apply pitch correction to 31 to 40 second region.I have tried by splitting the region on either side which forms a mini clip inside the original clip and inserting the filter into it which works. But the transition to and from the original clip to the split section is clearly audible like a badly done edit. I could use crossfades but is their a better and simpler way to do this? Is it possible to drag and highlight a region and apply the filter to the highlighted region in Tracktion without actually splitting the clip? This would be very useful as I could for instance apply compression to just one region of a clip instead of the whole clip.
Help anyone?

Add the filter to the track and automate it for just that section of the clip.

or do the same with the filter on just the clip

If you try this, you'll find out that the tails of the reverb will be trimmed exactly at the end of the clip, so it doesn't work that way unless your clip has lots of 'pad' silence at the end of the section you want reverb applied to.

Automation is the way to go as suggested above.

well for a pitch shifter (as per the original post) I would find it easier to set up the exact settings I want on a slice out of a clip, then automate the wet/dry to get rid of any pops, a reverb tail/delay line cutoff can also be used to great effect

Assuming there's no reverb tail to worry about, couldn't you also hack up the clip with "/", drop a filter into the clip that needs the effect, pull the edges just a wee bit over and auto-crossfade?

yeah - what's too complicated about that? setting up automation for it is going to be a lot more work and less intuitive to glance across; if you just chop it, plop a filter onto the new bit, extend the edges and autocrossfade, you're done, and you can see that it's a separately processed bit

@ lunch and haydxn,

Yes, this does work with the add filter to a chopped clip solution. Here's a FR:

When dropping an audio DSP filter onto a clip, wouldn't it be nice to have an option to automatically pad the beginning and ends of the clip with a user-specified value, complete with a cross-fade thrown in for good measure?

It seems like we already have this.

If I have to click somewhere to define the user-specified-value, enter the value, then click again to apply it, I can already just click and drag each end of the clip then click auto-crossfade. Seems to me just a different way to skin the same cat, unless I'm misunderstanding.

I guess it depends on how it's implemented. If the option popped up each time I wanted to drop a filter into a clip, I'd probably be annoyed.

I rarely do 'per-clip' FX anyhow, so I'm not really much of a person to have an opinion on it.

i stick filters on clips all the time. it would annoy me to the maximum if it did anything other than just apply to the clip when i dropped it on. i really don't think there'd be anything to gain from having another feature like that, without making it needlessly cluttered. sorry, i just don't think it's a great idea.

Why not have it as a handle (like the fade in/out ones) that trails at the end of a clip and so could be extended out as far as fx tails need to be applied to the clip?

Or have it pop up once with a "never show this again" checkbox, although that really doesn't seem Tracktionesque.

This is what I have done but I don't like fiddling around with crossfades if the music very continuos at the crossfade point which can also be audible. I was looking for a seamless transition. In practice I don't need this very often. I still think a drag and highlight option would be perfect no messing with crossfades,automation etc. Thanks everyone for all the suggestions. I will try them and see which ones work best for me. Cheers

There's nothing more audible than a continuous part immediately changing its sound.

Of course, you can make the crossfades as tiny as you want. It's just a matter of zooming in closely enough, and making the overlap only a few ms, or whatever the shortest amount allowable is for an 'auto crossfade' within T.

Mind you, at a close enough zoom, you probably won't even need to cross the fade, but it never hurts.

If you're already zooming in that close, another thing you can do is just drag your 'sliced' point to the nearest zero-crossing. It won't be 100% effective, but in many cases it'll help.
