Problems with nls
I'm trying to fit the Bass Diffusion Model using the nls function in R but
I'm running into a strange problem. The model has either two or three
parameters, depending on how it's parameterized, p (coefficient of
innovation), q (coefficient of immitation), and sometimes m (maximum market
share). Regardless of how I pa...

Bass response with Ogg Vorbis
I'm a bass player, I admit it. I came across a number of people
talking about bass response with Ogg Vorbis and it piqued my interest,
I live for this stuff.
I am using the Ogg files to distribute songs as converted right from
the 32 bit masters. This is a much different thing than ripping a 16
bit CD audio...

Fruity Loops
With Winetricks, Fruity Loops seems to be working well. The only thing
that is not working right now is the packs. I can't figure out why the
packs aren't working. If I click on the bass pack, it produces sound;
if I click on one of the choir packs, no sound is produced. Linux reads
the bass pack as pcm encoded. Linux isn't able to read all the packs
that aren't working. I know that wav is a wrapper but if the bass pack
is wav and the choir packs are wav then why is...

connect to bass.directhit.com(65.214.36.12):2401 failed: Connection refused
Hi,
According to http://www.openssh.com/portable.html, I tried to update my
openssh_cvs tree by CVS. And got an error.
$ cvs update -dP
cvs [update aborted]: connect to bass.directhit.com(65.214.36.12):2401 failed: Connection refused
Why? And from which cvs pserver can I get the latest openssh-portable?
Thanks.

Issue with signals with lots of bass
Hi,
We've just found an issue when encoding signals that have very powerful
bass (e.g. a loud 40 Hz tone). Turns out that was a combination of the
MDCT leakage with some inefficiency in the VQ search. There's a
tentative fix for that in git, which I'm encouraging everyone to test.
To enable the fix, look for these lines in alg_quant() (vq.c):
#if 0

Is this just anti-Ogg FUD?
I was recently talking to a friend of mine who produces what's widely
referred to as "techno", music that's heavy on electronically generated
loops and effects, samples, and has plenty of bass.
He doesn't like ogg for a few reasons - he sent me a rather long email, and
I've stripped out the nonsense from it (he has some technically irrelevant
reasons for not liking ogg) but he also made some claims that I wanted to
follow-up on.
I've modified his email and included the p...

RC2 and bass
...I believe this is the first time I
have noticed it. It is definitely the first time I have vorbis encoded
this song.
Try encoding They Might Be Giants - Istanbul. Go to offset around 50
seconds. It should say "Maybe people just like it better that way."
However, the maybe is pretty bassy (low pitch) and is just gone.
Anyway, RC2 is so much nicer at 128Kbps than MP3's are (sans some of
these pitch issues).
Nice job everyone!

CVS server not responding
Hi,
the anonymous CVS server for portable OpenSSH does not want to talk to
me:
> % cvs upd -Pd
> cvs [update aborted]: connect to bass.directhit.com:2401 failed: Connection refused
Looking at http://www.openssh.com/portable.html,
":pserver:cvs at bass.directhit.com:/cvs" is still the recommended
repository.
Is this a known problem?

...f results below) and running
ppr after sorting the datasets by idnum (second and third sets of results below).
At first I thought that perhaps the regression parameters are different but the underlying
results are equivalent but predicted values are significantly different. I tried
increasing the bass parameter, thinking that perhaps I was overfitting the data,
but the differences in the regression parameters remained. Finally, I originally had lots
of other RHS variables, including indicator variables; stripping those variables out
did not change my findings, as shown below.

Export nls object to text file
Hi all,
I am new to R and have some trouble with exporting results from a non linear
squares object (.nls), would be very thankful if anyone could help me.
So what I'm doing is a Bass modelling of some data. The result is stored in
the object "Bass.nls". I want to export a matrix with the three columns:
observation number, actual observation value, predicted observation value.
Can I do this somehow? If not can I export the full nls object somehow? When

Sensitivity to sounds with frequency
...hen two tones of two different frequencies sound equally loud, what's the
(rough) relationship between their power? This is for percussive sounds
in music, but I assume it's roughly the same for all sounds. The ear
seems more sensitive at high frequencies. For example, when you alternate
bass drum and high hat, and you adjust them until they both sound about
the same, the RMS power of the high hat is a lot smaller than the bass
drum. Is the sensitivity roughly 1 / frequency? 1 / sqrt(frequency)?
Thanks,
Martin

A new Open Source .Net bassed Vorbis/Theora Library and Sample Player
Hi all,
My company KISS Intelligent Systems is developing a content
distribution platform. Part of this requires the client software to
play audio and video. When we started we looked around and couldn't
find anything that could quite do what we needed, so we wrote our own.
We have decided to open source (LGPL) the library we created.
The library is designed to be cross platform, however we

Beta4 artifact/bug in the bass area
Hi!
Today, I found an encoding bug with a new tune by me.
http://www.uni-karlsruhe.de/~us87/ogg/vorbis_bassrumble_demo.rar (2.1MB)
contains the original .WAV in 16bit/44.1kHz and an .OGG encoded at
350kbit/s. I found the bug when listening to the 128kbit/s version, but
encoding it with that high bitrate didn't change a thing.
The deep bassdrum contains a rumbling, knocking sound (the first time i

Multi-channel labels in Vorbis comments
...for stem mixing,
something that is compatible with sharing our mixes on the open web -
legally, of course - but could also be used by record labels that sell
tracks to DJs.
For example, eight channel Ogg Vorbis files where the first two tracks
are a stereo mix of the drums, third and fourth stereo bass, fifth and
sixth stereo vocals, and seventh and eighth tracks everything else. This
means that you can mute or solo individual stems in the mix, giving you
the versatility of four-deck or eight-deck mixing but without the
problems of keeping many decks in sync.
It seems that Ogg Vorbis already has...

Notch Filter in AEC
...w frequencies - e.g. G.729 rolls off its input
hard, with a turnover at 140Hz - their whole coding methodology tends to
break down without that.
The telephone network normally rolls off hard below about 300Hz, so this
actually perfectly normal voice for a phone call.
A second reason to remove the bass frequencies is if you don't you can
get nasty echoes if the audio is sent to the PSTN. Analogue PSTN
interfaces don't always remove the bass frequencies, and digital
interfaces (BRI/E1/T1) never do. If you sent those frequency through an
analogue segment of the network, the hybrids can do h...
