ABX at q8
Hello!
First of all, 100x thanks to Monty and colleagues: you have done an
excellent job! I just didn't believe my ears when I first tested Oggenc
1.0 at q0 to q1 - it sounds AMAZINGLY GOOD !!!
But as HDD drives are getting larger and cheaper, most of us move toward
higher quality settings ......... I use q8, because:
- I was able to ABX some test samples up to q4.99
- at q8 Ogg is still

Can someone ABX 60.wav with 60.ogg -q 0?
Cheers, AGS.
P.S. Garf/Erik, I have included some comments from EAQUAL's author.

133 kbps stereo killer sample
Hello! I found a sample I can ABX successfully when encoded at
133.333 kbps. I was targetting 1 MB/min.

floex.wav is 4:54–5:04 of a lossless copy of 'Forget-me-not' by
Floex, downloaded from http://store.floex.cz/album/zorya
floex-133.opus was created with `opusenc --bitrate 133.333333 floex.wav

ABX Samples?
Anybody know where I can find ABX samples (original and ogg) that used
RC3 or better encoding?
The only ones I've been able to find are RC2 (or RC1)
PS - on a side note, on pcabx.com's "very easy" training samples, I seem
to be completely deaf to the differences between the "Original" and
their "test" samples. (Distortion sample only), but I do hear

Opus vs AAC (endurance test)
using iTunes i've noticed that AAC is
very good at re-encoding own lossy sound.
let's test Opus!
neroaacenc.exe -q 0.75 -if 000.wav -of 001.m4a
neroaacdec.exe -if 001.m4a -of aac001.wav
wavdiff.exe 000.wav aac001.wav
Comparing 000.wav - aac001.wav...
Max diff: -17.3867dB
RMS diff: -33.0851dB
Mean diff: -32.4582dB
opusenc.exe --bitrate 512 "000.wav" 001.opus

RC3 killer sample?
I was able to ABX 60.wav from the lame samples up to q=5.9 (13/16 tries at
that quality level). I failed to ABX it at q=6.0 (8/16).
The sample exhibits a pumping artifact; a "fluttering", if you will, of the
amplitude. The effect becomes more pronounced as quality setting / bitrate
decreases.
Any thoughts?
Also - if anyone replies to this, could you CC me a copy? I'm not on the

Extracting formula from an lm object
I want to extra the part of the formula not including the response
variable from an lm object. For example if the lm object ABx.lm was
created by the call
ABx.lm <- lm( y ~ A + B + x, ...)
Then ACx.lm is saved as part of a workspace.
I wish to extract "~ A + B + x". Later in my code I will fit another
linear model of the form z ~ A + B + x for some other response variable z.

OT: good headphones?
...ny brands to avoid? I'd be using these for mixing
multitrack recordings and editing CD audio, not for general music listening.
I like to buy quality products, but price is somewhat of a factor.
(I guess you could say this question is Vorbis-related, because I'd also use
them if I were ABXing. With my current equipment (crappy passive PC speakers
in a noisy room) I can't even ABX vorbis at quality 1 from the original CD
source. But I suspect I have dull ears, too (which is a blessing, really).)

applaud.wav sounds worse in 1.0?
I've been running through a collection of hard to encode samples that the
lame developers use, and others, doing ABX testing at various quality levels
looking for my personal sweet spot. Last time I did this for RC3 I found that
most samples where pretty transparent around the 3.5-4 region (my ears aren't
that well trained, and I don't want them to be :-), but this time I noticed

133 kbps stereo killer sample
I halved the volume of the sample before encoding with
`sox -v 0.5 floex.wav quiet.wav` and now I can't ABX it succesfully anymore.
So the artifact I heard was just clipping when encoding or decoding.
Opus remains unbeaten for me at 133 kbps. That's totally awesome.

Deleting a variable number of characters from a string
I have a text processing problem I'm hoping someone can help me solve. This issue it this.
I have a character string in which I need to delete a variable number of characters from the string. The string itself contains the number of characters to be deleted. The number of characters to be deleted is proceeded by either a "+" or a "-".

Curve fitting
Hi!
I have a problem of curve fitting.
I use the following data :
- vector of predictor data :
0
0.4
0.8
1.2
1.6
- vector of response data :
0.81954
0.64592
0.51247
0.42831
0.35371
I perform parametric fits using custom equations
when I use this equation : y = yo + K *(1/(1+exp(-(a+b*ln(x))))) the
fitting result is OK
but when I use this more general equation : y = yo + K

Opus for audiobooks etc
I know the focus for Opus is low delay, but I've been watching its
development with interest because of the potential for audiobook/podcast
use, where latency is practically irrelevant. I hear the upcoming USAC
codec will give good results for this niche (though listening test
results don't seem to be available to the public yet), but I also hear
it'll be extremely patent

My motherboard/cpu/memory seems to hang when rsync runs...?
Is this just because rsync gives it a work out?
I may drop using this motherboard, since the store will not replace it, and
thinks it's a hard drive problem, and the board has no way to underclock even
as a test.
What about changing from 1300 MHz to 800Mhz AThlon processor... think that
would help an AZZA KT3 ABX motherboard work easier?

Opus vs AAC (endurance test)
Opus is specifically designed to survive tandeming but you need to keep the
frames aligned and not mess with the gain, which your tools probably do not
do.

Archival quality for music
This mail depends upon the fact that I don't have a couple of good
earphones ;-)
I read in the site that q=6 is a very high quality, but does it contain
perceivable differencies from the original? (for 95% of people, of course).
I also found q=6 to produce files slightly bigger (1/10 bigger) than those
produced with lame VBR q=2 (about 192 bps on average). I always thought
