I picked up RainMeter about two weeks ago... and ended up recoding a lot of different skins to try and learn the basics. What I really wanted though was a good performing audio meter. I tested a lot, perhaps about 30ish, but the performance on my machine (roughly 10 years old now) was terrible. So I put on my coder hat, found a simple bar skin, and started putting it through its paces to see what could be optimized. Note: This is a hog with 59 Measures and 59 Meters using the AudioLevel plugin. Thought I would share my results.
Changing FFTSize, FFTOverlap, and related settings: no noticeable difference
Various optimizations and changes to the Measures: no noticeable difference
<I could not find a way to reduce the number of Measures so moved on to the Meters>
Various optimizations and changes to the Meters: no noticeable difference
But... I did think of one simple trick which did work. I found I could reduce the number of Meters.
Original code snip:I snipped a lot of the code as redundant. I am sure you can imagine 59 of each of them. Well with a bit of tinkering I replaced the 59 meters with a single meter.
Surprisingly, at least for me, my CPU went down from ~32% to ~9%. Not much really changed in the code. My only guess is that under the hood Meters have a decent amount of overhead to process. So, if you want a simple blazingly fast audio visualizer, just use one Meter!
