Volume Limiter

(1/6) > >>

terrence1019:
If know there has been talks of inserting a volume limiting function (a la iPod) and that the prospect of inserting it into SVN code is low.

What if I were to make a volume limiting plugin? Would that be more preferably accepted?

Llorean:
I'm not sure I understand at all what you're proposing. How would it work? How would it offer any benefit over simply changing the volume? Or setting a pre-amp to limit the volume? Or replaygaining your files to limit maximum effective loudness?

markun:
yes, it should be possible as a plugin as well, but since you can't do that much when the plugin is running it would not be so nice.

Would you want your limiter also to raise the volume when the music gets too quiet, or only to limit the volume during loud parts?

Don't those scale the digital value, effectively decreasing the number of DAC bits in use, increasing distortion from that and decreasing signal to noise ratio?

I think only the volume actually scales the analog output of the DAC, allowing the full range of the DAC to be used. 

I think a volume limit option might help avoid times when while turning up the volume one overshoots into uncomfortable volume and it could help avoid volume levels which result in distortion.

Mad Cow:
On the ipod OF, it's just a limit on how loud you can set it. So say you don't want it to go over -10db, you set it at that and the volume would never go over that. I never really understaood the point of it though.
