Dynamic Split performance problem
Hi
I'm quiet new to this feature, I saw a tutorial that a guy used Dynamic Split on the whole drum section(8 tracks) and worked fast and well but when I want to do the same I encounter heavy lag(freezing,sometimes crash) specially on Gate threshold.
Tested on three systems :
one clip(44100 4 bar) on 44100 project
Intel Core i7-3970X Extreme, 32gb ram, 256 SSD, Win 7,Original Reaper 5.0.4
Core2duo 2.4 , 4gb ram , 1tb hybrid 8gb, Win 10, Evaluating Reaper 5.0.4
Quadcore 2.8 , 8gb ram , 1tb raptor 10000, Win 7, Original 4.6
All have the same problem.
Any thoughts ?

Dynamic does indeed have bugs.
See here: http://forum.cockos.com/showthread.php?t=137729
You'll just have to work in sections at a time to work around that.

It's normally fine but I was showing it to someone today and felt a lot more sluggish than normal.
Something might have changed in the way it's working.

Dynamic split is super slow if the item's rate or pitch has been altered

Humm, I wonder if this is something that's developed recently.
About a year ago I was using Dynamic Split a lot and didn't notice any problems.
I used it to do a lot of splitting of mostly 4 channel items, but also some 6 channel items.

Same problem here, its happened suddenly. Getting huge cpu spikes when I open Dynamic split and its sluggish to the point of being useless.

Did you watch that little video I posted?
Did you try just selecting smaller sections to split?
Dynamic split can truly only handle 30sec - 1min of audio at a time.

There is a slightly different alternative - auto split/trim - maybe that would also work for you?

Dynamic split performance Problem on short drum sample
Greetings folks,
I too was having serious performance problems with a dynamic split on a short drum loop today. I decided to move the sample from my system drive C: to my data drive D: and immediately there was a very noticeable difference in performance i.e. much improved. I have a Windows 7 system with a quad core Xeon 3ghz and 12gb of ram. The project only had the small drum loop in it on each occasion, no other tracks.
I'm wondering is it the fact that the file was located on the system drive that caused the issue ? It would be nice to know, can anybody confirm my suspicion please.
Cheers,
John.

Hi,
The only thing I can add is dynamic split has always been slow on mp3 files.

Yep, and also,
Use the detect first, separate thingie first thing before dynamic split, then convert (render items to new take)+(crop to active takes in items) your FLAC (slowest) or MP3 (medium slow) to Wav, default render is suppose to be Wav.
A little bonus is that stretch markers and scripts seem to prefer Wav as I have seen quantize/align flaws, but not on Wav, as far as I can remember.
For me, Wav works fast here with the detect/dynamic split on a i5-3570K.
