1.frag [file: fragment shader],

2.frag [file: fragment shader],

High (>2048, with 22050 Hz) values will decrease accuracy

Sample UPS Description
|
|
- 2048 -> 43.0 (low accuracy, cheap), use with < 60 FPS
|
|
- 1024 -> 86.1 (high accuracy, expensive), use with >= 60 FPS
|
|
- 512 -> 172.3 (extreme accuracy, very expensive), use only
|
|
for graphing accurate spectrum data with
|
|
custom modules.
|
|
|
|
If the framerate drops below the update rate, the update rate
|
|
will be locked to the framerate (to prevent wasting CPU time).
|
|
This behaviour means you can use a 1024 sample size on a 60Hz
|
|
monitor with vsync enabled to get 60FPS and 60UPS.
|
|
|
|
For high refresh rate monitors (120+ Hz), it's recommended to
|
|
also stick with the 1024 sample size and use interpolation to
|
|
smooth the data, as accuracy beyond this setting is mostly
|
|
meaningless for visual purposes.
