Changes:
- Split Natural Dynamics into 4 sections, to make things more readable (no further changes, have been busy with the Mac version the last 3 days).
Meaning of sliders:
Initial detection
This section controls detection of which sounds need to be boosted
- Effect strength: How strong does the filter work. 0 = no action, 1 = standard etc.
- Dynamics detection: The effect is reduced if the signal is already very dynamic. This slider offsets the detection of how dynamic the sound already is. Result is displayed in the bars on the right (gray dotted part that comes in from the right: The bigger this is, the more dynamic ND thinks the sound is, and the effect of the filter is reduced as indicated by this gray dotted area).
- New method. This is a bit weird, there was an 'old' method that people liked, but I thought that I could make something better. This enables that "better" method; the following sliders only have an effect if New method is enabled!
- Multiply above: I calculate how much the current sound is compared to the 'average' level. 0 = equally loud, 1 = twice as loud etc. This calculated level is multiplied by Multiply above. Basically, bigger value means more effect.
- Subtract above: This is subtracted from the result of the multiply. Bigger subtract value means that the level where the filter becomes active shifts upwards (sounds must be louder for the filter to do anything).
- Clip above: Volume boost may never be more than this. (1 = no boost, 1.5 = 50% boost etc.)
I see that I can come up with much clearer names for these last 3 sliders, and I will in the next version.
Punch detection filter:
After testing a bit, I noticed that you only want to boost sounds that are 'punchy', in other words, if the volume goes up rapidly. This filter removes boosts found in the first step if the sounds are not punchy.
- Use punch: Turn this filter on. You should actually never turn this off, except when you're tweaking the settings of the initial detection.
- Punch rise time: Over how much time difference do we measure volume differences. Should be bigger for lower frequencies because a waveform takes more time to go up there.
- Punch spread time: The area in which we allow the volume to go up (see initial detection) is related to the punch rise time, but may be made a bit bigger.
- No speedup: O this should have been in the initial detection section
There's probably no good reason to turn this off; in the initial versions it could take quite long sometimes upto 10 seconds) before the filter stabilized after a big volume change; the speedup fixes this. I've made it possible to turn the speedup off to test for bad effects, so far I haven't noticed any.- Punch multiplier and subtract: Again, we calculate how much punch there is at each location; the calculated value is multiplied by multiply, then subtract is subtracted from it. Can be used to shift the response behavior.
Smoothing:
Controls how fast the volume may go up (should be fast!) and down (should not be fast, to avoid bad effects).
Note: I know that there are a lot of settings and that they are rather complex. I'll try to reduce things later, but first the filter must work properly.
