Hi Brian and others,
No idea why you want to have a final limiter if the peaks never go over 100%. Well it sounds strange in digital audio anyway 1111111..1 you can't really go beyond that. ... except if you set the max volume below that certain (digital) level.
The fact that it doesn't really seem to clip, go over a certain level or cause audible distortion says to me that you don't need anything behind it.
The loudness thing, well I guess it is just a name. Maybe Hans can define what it actually does?
I'm tinkering with it some, but I am unable to turn the volume up today due to the, ummm, surroundings (people will complain), so I'm not sure the overall effect.
One other thing I should state is that I'm not any kind of professional sound / recording engineer. I did some volunteer work with some churches and small concerts nearly 20 years ago, but nothing beyond that. I don't have any specialized training or any special equipment other than my ears. So, you may very well be onto something about peaks never going over 100%, although I am allowing peaks up to 150%
Anyway, my main question was about SSE usage. I have an Athlon 64 3700+ (San Diego core), so my CPU will do SSE3, but there was a post back in July from Hanz saying that a processing library he was using had dropped SSE2 and SSE3 support, so I was wondering what was being used now, and if it isn't at least SSE2, can another library be found to provide SSE2 support? Also, has any effort been made for SSE3 support, because SSE3 does give a few options that are DSP-friendly.
