Hi all,
SecretRabbitCode was recently included in a test of a number of
commercially available sample rate converters and while it wasn't
the best, it certainly didn't disgrace itself either.
The results are here:
http://src.infinitewave.ca/
This test gives me yet more incentive to continue my work on coming
up with a new improved algorithm.
Cheers,
Erik

congrats Erik. as you said, not the best (r8brain ?) but compared to the
stuff in some proprietary DAWs, pretty great. quite amazing how bad the
ProTools and Sadie systems were ...

r8brains was good as was iZotope, Wavelab/Crystal and a couple of
others.

Protools wasn't *that* bad unless you look at it on a bang per buck
basis :-).
Sadie however was appallingly bad.

design than any other programming language ever.

I should also thank Ben Loftis of GWL (Harrison consoles)
for hooking me up with the people running the tests so that
the Rabbit could be included.

Good to see SRC stands up so well against the proprietary stuff.
Nice work. (I particularly liked the 180-degree phase shift in Sonar :-)).

I once tried to further improve your sinc code, using longer and better
filters optimized using the Dolph-Chebyshev window and a different balance
between bandwidth and stopband attenuation, of course at the expense of
performances. It turned out that I couldn't improve the results above a given
threshold because of a sort of (really low level) jitter in the timebase
calculation. With integer resampling factors, where the jitter dind't appear
because of the way the timebase is computed, the results where on pair with
CoolEdit/Audition, which is among the best in that test.
It was long time ago, so I don't remeber exactly what I did, but this
information might be useful in improving your code. Removing this timebase
calculation problem, if it can be removed at all of course, probably will make
your code close to perfection, making the final performace just a factor of
the quality of the filters used. Regarding this, you might think about an
option to load the filters from file... :)
Of course this is just academic, because I really doubt that the tiny
artifacts introduced by SRC are audible at all, even in its current
implementation. Just a matter of winning the race. :)

Hi
I need help!!
I have just installed 64studio on a SATA disk (Hitachi 250 gig)
I have windoze on the first disk (HDA) and Ubuntu 32bit on the Secondary
Master HDC (?)
I did have an ide 150 gig but SMART informed me it was bad this originally
had 64studio on it.
I have removed the 150 and got the sata 250 for 64studio.
After installing It asked to write the boot to the MBR I said yes.
Now I can't boot at all no grub nothing just a cursor blinking at me, black
screen.
Any ideas how I get my stuff back the ubuntu stuff I really need.
Cheers
Bob

The current algorithm (originally described by Julius O. Smith)
has its limitations. Thats why I have spent a considerable
amount of time trying to come up with something that has lower
computational requirements as well as better quality :-).

and did you get it? Which kind of algorithm are you using now? Quite curios...
Bye,
P.S. The CoolEdit algorithm provides excellent performances but I think it
works only for rational resampling factors, isn't it? This makes those
performances much easier to achieve, I think.
