i am using elemental audio InspectorXL. And all snd files in 2.0b6 are cut to 3min by default and the audio output is clipping to begin with. that could be the cause of some of the sound compression. Anyways i will try to do some more tests on different formats to see if they are clipping the output as well.

This was without normalization or optimizing sound functions.
Normalizing is only for low level signals anyways. this is too high and when normalized, gets even more compressed.

And if you are talking about 8000 clips being normal: for tape yes, for digital NONONO

Also the songs specifically were from YMrockers and DropDaBomb snd files but other snd files acted the same way with the normalize function off or on

It's completely normal for major label CDs to clip frequently since 1998. Modern ProTools compression plugins let you create full-on square waves that don't sound bad to the untrained ear - you'll just notice your ears become "fatigued" after a while.

(Ironically, this means most CDs are already shipped at such a bad quality now that MP3 can't do any further damage to them).

PSFs aren't good for slow computers... especially for my 300 mhz G3!

Well, yes, playing them involves emulating most of a PS1 except the graphics :-) (And some even require the GPU status bits to at least show Vblank properly - ugh).

re: R belmont. Yes, I know I am a mastering engineer and often get paid to fix gain stages in protools, logic, ableton, acid,etc.. mixes before i master because good mastering only accentuates the audio and as a result the defects as well. But i sure hope this isn't a "2 wrongs make a right" analysis.;p

and yes, i have hyperaccusis (increased sensitivity to air pressure changes of all kinds, due to the basila fluid in my choclea existing in higher levels than normal) so fatigue of the ears and consequent headaches is a big avoidance priority for me. But the ear itself is the most sensitive part of your body and is easily damaged for anyone. It is also one of the more mysterious parts of the body due to it's decomposition rate of less than a few hours after death. so most of the world is still "in the dark" about the ear.

Also the clipping (overdriving of the signal) adds to the un-intentional compression of the sound.

We've got a problem...

In SuperMarioBrothers3.nsf, some songs play with the kickdrum repeating very quickly. Oh dear...

techne: no, I'm not at all claiming that we should abandon audio quality even though the RIAA has :-)

AO applies no gain stages to the output of the ST emulation though, assuming normalization is off. Perhaps I'm misconfigurating SC68 somehow.

i am a bit busy but in the next week i can thoroughly analyze each supported platform (except QSF since i have none) and list songs used and and a whole slew of diagnostic information that may be helpful in applying precise changes to any of the formats gain implementations. Anyways since i take it you are an engineer too, i thought you might be interested.

It seems maybe there are some timing problems with the PSF format? Have only tried the rip of Xenogears from Zophar's Domain, using a G4 1.67 ghz Powerbook/ OSX . For instance, the track "Tams, the Man of the Sea" plays fast vs. winamp/HE (PC/XP) and my pretty well burned in recall of the actual PSX track. Sounds great, but it's the wrong tempol wink This seems to be the case for the whole PSF in my limited testing.

Yes, I feel something's weird with the tempo on some songs with PSF files. Aren't we lucky that PSFPlay is now not the only Mac Only PSF player?
