Selection with Magic Wand becomes slower and slower

When selecting a large number of datapoints, the Magic Wand-Selectiontool becomes slower and slower, until it is not usable for practical purposes.
The speed of selection should be (almost) independent of already selected datapoints.

(Btw. in this picture, we see a certain visual contrast enhancement. And then afterwards trying to select certain datapoints. With contrast enhancement on the fft-datapoints, this would not be necessary, though…)

From my understanding I believe the main developer @Robin_Lobel is working on this for the next release.

IME I find when selections accumulate and mount up, slowdowns occur

harmonic selection being very quick to become sluggish

try it: set your Count to 50+ and make a bunch of additive selections and performance will become very sluggish

it is as though, each selection portion is considering every data point in the spectrograph over and over…and then subsequent selections do the same

to use your visual analogy, it feels like a stack of photos (spectrograph) with one selection per photo; rather than an accumulation of selections on one photo; hence filling up RAM with these multiple repeats of the spectrograph…and most of us running A LOT of RAM…many with 64GB…now, obviously different OSes handle RAM differently…

at least that is what it seems like in my imagination

I just make smaller selections in my typical workflow after getting bitten by trying to select too many additive selections of the the program material

I seldom add more than 5 min source into SL

This seems like a good example for the runtime of an algorithm. There is a slight difference between O(1), O(log(n)), O(n), O(n Log(n)) or O(n^2).
The selection algorithms right now seems like O(n^2) today.

Great news indeed! Another feature I’m also looking forward to (for the next release) is a live monitoring audio analysis spectrogram/spectragraph (similar to FL Studio’s wave candy). There is already live monitoring analysis within Spectralayers but it lacks. I would like to see the live monitoring analysis within Spectralayers improved with options to combine the stereo image into one (just like within wave candy). I also am looking forward to certain improvements like snapshots and freezing functions (like in wave candy). The goal for me is to run live monitoring analysis 24/7 on a separate secondary 55inch 4k monitor.

Right now the only tool that is capable of live analysis monitoring is fl studio’s wave candy however it doesn’t scale up to 4K and seems to be limited at 1080p.

Once the customers get a small finger, they will rip of the whole arm or even more… :slight_smile:

We love Spectral Layers and now, we want it all…
