Title: Volume Protection Question
Post by: Bccc1 on April 16, 2013, 02:59:07 pm
Do you have some Bugtracking site, where I can report bugs or am I suppposed to do this in these Threads? I'm wondering because I pointed out a bug about the volume control in the release thread of 18.0.149 and neither got it fixed nor commented.

I qoute myself in case these release threads are the right place:

When I drag the volume control to the right, it jumps a bit left, so it's kinda fighting against the bug to increase the volume  

Decreasing the volume is no problem.

This Bug only occurs then Options->Audio->Volume Protection is active.

Something seems to have changed since I posted that: now the volume control doesn't jump to the left, just the mouse.
To visualize, i made an animated gif. I'm only moving my mouse to the right in this clip. This behaviour is much less pronounced if I move the mouse slower.

@Bccc1
That's what Volume Protection is supposed to do.

My fault  :-[
I thought it was like a limiter at the end of the audio chain  ::)
Thanks for the clarification

There are three types of limiters in MC.

1) Protect Mode, which is a digital fuse of sorts.  It triggers if a really wonky signal spike or DSP engages.

2) Clip Protection, which turns the volume down if the signal exceeds 100% and then slowly turns it back up if there are no more spikies.  Enabled or disabled from the lower-left corner of DSP Studio.  In my opinion, it should be left enabled in almost all cases.

3) User added limiters in Parametric Equalizer.  

For #3, the 'Subwoofer Limiter' is especially neat, because it filters low frequencies and leaves higher frequencies when possible.  This way, the energy at 80 Hz doesn't go away because of a huge spike (almost) no subwoofer could reproduce at 20 Hz.
