why does audition lag on longer files?

[DavidSweeneyBear]

Hey all...

I work on longer audio files regularly, e.g. 30 - 50 minutes.

I find that the longer a file is (and I also work with markers, so the file is marked with maybe 2000 or so markers too), the more Audition lags in scrolling the playhead and also deleting sections of audio.

I have v.12 installed (2019) on Win 10 pro on an i5 quadcore (3rd gen) with 16 gigs ram and 10 of those dedicated to audition. I don't have any excessive background processes runing either.

Without the markers, it's a bit improved, but still pretty laggy on longer files.

As a work-around, i tend to chop the files down into 10 to 15 minute sections for editing.

playback, effects plugins and processing are all fine on longer files, but it's just the tasks that seem to involve navigating around the file (except skipping from one marker to another, that's fine) or anything that causes the file to have to be readjusted in terms of postion of data.

Any ideas what might be causing this, whether there are any fixes, or whether that's just how it is?

There are several things that come to mind like if the source file is on the same drive as the cash/preview file, or if the hd is not a solid state, but it sounds like you had it working before an update. If it did work then a setting change may have reset one of your settings like other Adobe apps next to the 10 gig dedicated you have selected, and as messed up as it may sound I remember I have to keep them equil or close or they get into conflicts. that was a post here and I will try to find it for you as well as run an expirment or two. Hope this helps.

Yes I was running on one SSD, being between computers at the moment. Have tried on my new system although with HDD not SSD and the lag was less. Hoping it will be even less once i get my external SSD set up.

As Abigail777 mentions if it is not an SSD then you more than likely experience lag

Also make sure that the sample rate of the session file is the same as the media so there is no resampling being done on the fly
