[RFC/PATCH 15/15] guest: virtio device support, and kvm hypercalls
From: Christian Borntraeger <borntraeger at de.ibm.com>
This patch implements kvm guest kernel support for paravirtualized devices
and contains two parts:
o a basic virtio stub using virtio_ring and external interrupts and hypercalls
o full hypercall implementation in kvm_para.h
Currently we dont have PCI on s390. Making virtio_pci usable for s390 seems
more complicated that providing an

codec online test from "that" German IT-Magazin C't
Salve,
till the 28. August midnight the magazin c't has a codec test
between AAC, MP3, WMA and Vorbis Ogg online.

c't listening test: Ogg problem at 128kbps
Hi there,
I'm new to this list, and in fact rather new to the Ogg/Vorbis codec
altogether. I recently downloaded the test files from the test
conducted by the German computer magazine c't (this was mentioned by
someone here recently).
The idea was that you were given seven WAV files each for 64kbps and
128kbps, and had to rate them. The files were randomly chosen for each
participant.

Serious, inacceptable artefacts with Ogg Vorbis
Hello developers,
I recently participated in a public listening test that was held by
German magazine c't. They had two categories, 64 kbps and 128 kbps.
I only participated in the 64 kbps test where there were 7 .wav files,
with 1 of them the original one and the other 6 being encoded with
different encoders. Without knowing which file was encoded with which
encoder you had to give each

TwinVQ versus The World
The last few threads have really been interesting. Technologies
that are currently on the market are MP3, RealAudio, and Windows
Media (pre-version8). Technologies currently in progress or
just shipped are Ogg Vorbis and mp3pro. I don't think anyone
has mentioned TwinVQ on this list. While exploring alternatives
to MP3 (which is when I also found Vorbis), I noticed TwinVQ. I

Newbie trying to throttle bandwidth
I apologize with what may be some very basics questions. I''m trying to go
through sections 9 and 15 of the LARTC FAQ, but my head can''t quite grasp
what''s going on. I''ll keep going through them to see if something clicks,
but meanwhile I was hoping someone might point me in the direction that I
should focus my efforts.

vorbis vs. mp3 vs. realaudio
Hello,
how good is the quality with very low bitrates like 16kbps mono. 16
kbps files compressed with lame sound awful, realaudio is much better.
Will vorbis sound as good as realaudio with low bitrates?
How fast is vorbis (in comparison to lame).

Helix into Icecast2 loopback
Hello.
I've made some progress on the issue. I found a tool called TrPlayer which
is a text mode front end for real player - initially developed for the use
of the visually impaired. The theory is that I can use this and pipe the
live stream into vsound which then in turn is passed into ices or another
source client. Trouble is, I'm having all sorts of trouble compiling

make lo-fi sound as good as RealAudio?
Can someone who really knows the Ogg command-line encoder, help recommend the best setting for 33.6k modem stereo music streaming?
(56k doesn't count cuz many people's 56k modems don't work at a full 56k, and I want them to be able to surf CD Baby at the same time as listening. 2 minutes / 120 seconds of audio should be about 400k.)
I'm at my wit's end: tried everything I

Helix into Icecast2 loopback
Hello all,
I am a little new to Linux so I would appreciate some assistance with this
issue.
I have been running a Helix server streaming RealAudio encoded content live
and on-demand for a while. For the live stream, I use the Real equivalent to
Ices which on the Helix platform is called SLTA. All the content on the
server is encoded as RealAudio.
I have also successfully setup an Icecast2

Shawn sent me a copy of the non-Direct Sound version of this output plugin,
and I'm hosting it on my web site's rare software page:

I've found it adds far more smoothness and clarity to various low
sample-rate audio files, including an 80-minute speech I mentioned
previously, due to my soundcard's approach to D-to-A conversion

low bitrate sounding better? (20k-30k)
At SxSW I ran into the Xiph gang and someone said something in passing that the new version of Ogg Vorbis would have much-improved low-bitrate quality.
Wondering - true? Details? ETA?
At CD Baby all lo-fi soundclips are still in the SFERA format*. At 20k bitrates, they sound GREAT which is why I stick with it, but I'd much rather switch them ALL over to OGG if there was a way to make

Poor quality of low bitrate encoding
In testing, I have found that both MP3 and RealAudio 3(!) are much
better sounding at bitrates from 8 to 40-something kbps than Ogg
Vorbis. This definatly needs drastic improvents and I know that 1.1
will be focusing on improvements in those areas but that seems pretty
far off(a few months minimum) which leaves low-bitrate streams sounding
pretty bad.

Newbie STILL trying to limit bandwidth - is this script wrong?
My previous message
(http://mailman.ds9a.nl/pipermail/lartc/2004q2/012285.html) didn''t generate
any replies, so I thought I''d try posting what I''ve done trying to solve my
own problem, in hopes that someone will take pity and show me if/where I''m
going wrong.

Seeking in a static icecast stream
I currently utilize Icecast on my website, but I am looking for the same
kind of functionality as I get with realaudio server when I stream
static content - namely, the ability to seek, show the time remaining,
etc, especially with Vorbis audio.
I realize the intent of Icecast is to serve mainly live, streaming
content (or at least radio-style content), but I utilize it mostly for

Status of RealOne plugin?
I'm trying to convice a webmaster to start offering Vorbis in addition
to his current RealAudio 3(GAH!) web streams. I was just wondering what
the status on the RealOne/Helix DNA plugin was so I could include it in
a letter I'm going to be sending him today.

IceCast + Real Audio?
In the notes for 2.3.0 it says that IceCast can function as a
RealAudio/Helix server. Does this mean that it does the quality
negotiation as well, ratcheting the bitrate up and down if it needs to?
Or am I reading this all wrong?
Thanks.
