Integer is King? - the challenge

[mustgroove]

Can someone summarise the thread so far, in about 2 or 3 sentences? 21 pages of flaming/trolling (flolling? traming?) is not something I wanna read through right now...

Did the fixed point version sound better to anyone?

[JCJR]

Hmmm. Never since the historic eruption of Mount Krakakaka has it gotton this deep?

[#The fREaK!]

Hurrah for topic drift! This and the original thread both have truly floating points.

No need to be so... fixated. Though perhaps it is integral to the discussion.

[jupiter8]

Maybe the test plugin is not working properly with my host, but I hear zero difference. Plus phase inverted tests always reveal differences so low they're irrelevant.

ORLY?

The notion that the difference really is to small to hear is of course inconceivable ?

nollock: if I consider aliasing that sounds good smart, I say it's smart.

So because an instrument was built with noisy 12 bit DACs and a mono output strictly for cost reasons, it's smart?

I don't think there's anything "wrong" with my definitions

Besides the fact that you don't know what you're talking about, you mean?

I've read some bizarre things before, but your "smart aliasing" takes the cake. Could I please have some of what you're smoking?

ew

This thread is not going to heal itself

PLEASE don't heal it. it's surely a bad habbit of mine, but i want to see more people talking about stuff they think they know all about, only to go down silently after 20 posts making theirselves look ridiculous.

this mourning i fired up my ADC. it's real smart, i know that because i built it myself, and i'm smart myself, in fact, i invented smartness. and that's not subjective, it's a fact everyone knows, it's the unspoken, though never referenced truth. and it's friggin' red coloured. the 255 000 000 kind of red, i mean.

sorry, couldn't resist.

keep up the good work guys.

props to the thread starter btw.

[whyterabbyt]

shit, i didnt realise this was the 'integer test' thread, was thinking it was the original 'integer is king' thread. my sincere apologies folks...

[Glassback]

The best "proof" you'll ever get is from Urs's post at the buttom of the previous page.

Shy, please take my apologies, my post is all made up garbage.

This is the point where I would have gone and hidden under a rock somewhere remote, instead of flogging a dead horse!

[JonHodgson]

i invented smartness. and that's not subjective,

Actually I think you'll find I patented smartness before you came up with it. My lawyers will be contacting you about licensing fees shortly.

[aciddose]

ah, however you'll be destroyed when i unleash my all encompassing submarine patent on ingenuity.

[duncanparsons]

haha, but my patent on patents will trump you, I also own the copyright to 'copyright' - I've just been hugely benevolent up until now

It appears to me that you are being smart... please cease and desist immediately.

[Glassback]

But, but, I thought 'smart' was merely subjective and can't actually be proved except by made-up smartness?

I think sir, you owe me a royalty first.. shall we call it quits for now?

it doesn't sound like horrible plain aliasing.

True. The carrier feedback of the DX-7 (strangely followed by the DX-100) generates almost perfect white noise, if set to 6 or up. The only thing that beats this is a noise generator based on Mersenne primes running on IBM PowerPC processors. It's almost as good on Freescale chips, but these lack a bit of the pink noise spectrum, maybe because the Freescale processors use the same registers for integer as for floating point, which somehow diffuses the precision. X86 processors are a whole different problem. Due to the fewer general purpose registers a strange side effect happens where some registers would auto-frequency-modulate themselves, adding an extra portion of aliasing. This is called register aliasing ( http://www.fefe.de/devel/aliasing.txt ), and it's a very unpleasant thing which especially AMD users react weird about (as numerous discussions on http://www.anandtech.com/ clearly prove). However, Mac users will be happy to know that Intel has recently improved register aliasing - it's now called pointer aliasing ( http://american.cs.ucdavis.edu/Micro27/html/abst13.html ). As pointer aliasing happens in the imaginary part of the dsp process - which is discarded ion favour of the real part by the asio/coreaudio driver), it does not contribute to the sound in an unpleasant way, so Intel macs are pretty clean sounding here. Maybe too clean to be pleasant sounding.

Tell ya what?

I'm in the transition from my old AMD 3000+ mobile to an intel Banias 1,5GHz.


I did this test on both machines.

same soundcard, same audiosoft, different windows.

I'm a little afraid to say it, because its so nice and peaceful here for a change.

And so far its all just about playback.


I expereancing my old AMD as jittery. It has a certain high end color that is not present on the intel.


..... please ignore this.

PS. Christian could you maybe consider to debug this EQ a little and bring it out with that Z- algorithm?
