Developing SoundFont FLAC compressor using libFLAC

Yeah, no problem. FLAC gives a nice decrease in size as is and adding
this kind of support wouldn't break the SF-FLAC format in the future.

I'll let the list know when SF-FLAC is finished, should anyone be
interested. I'm considering starting a FREE SoundFont compressor
campaign, so users will stop using SoundFont encoders that aren't
available on platforms such as Linux. This would also pressure some of
the existing formats to release Linux versions. In order to do this I
need to program a stand alone compressor/de-compressor utility that can
work in Windows,...

theora encoder reordering, order of puting data from DCT 8x8 blocks to huffman compressor, and puting result of huffman compressor to buffer bitstream memory
...frames).
I don't undestand one moment. Now i develop such stages:
1. From RBG(byer) to YCbCr converter
2. DCT processing (8x8 pixels blocks)
3. Quantizator of DCT coeff.
4. Zig-Zag of quantized DCT coeff.
and now i have uresolved last stage of compression - how i must send 8x8
blocks to huffman compressor? I don't understand ordering.
I must send all DC coeff (Y, than Cb,Cr), after all AC-0 (Y, than Cb,Cr)
.... after all AC-63 (Y, than Cb,Cr)? And put huffman compression result to
buffer memory like this:
huffman compression products of all DC coeff (Y, than Cb,Cr), after all

camstudio does'nt detect compressors. Err creating avi file
...own issue, after trying to run for the first time, it complained a missing dll (mfc42.dll). That was easy to solve and I got camstudio opening the recorder.
The problem started where, when I click on record. It says:
Error creating avi file!
I tryed so many things but the problem I found was the compressors list in OPTION -> VIDEO OPTIONS does not show any compressor.
I also add a registry entry but no change
Plz, does anyone could give to me a hint on how to solve that.
tks in advance.

VP3 Compressor Settings
...Prev and lpPrev members of the
ICCOMPRESS structure.
My conclusion is thus that each frame passed to the codec is compressed
individually and that the redundant information based upon previous frames
is not relevant to this codec (i.e. the codec does frame for frame
compression much like a Wavelet compressor and not like an Mpeg base
compressor).
Is my assumptions at least correct ? Because it does not seem that any
changes to the Key Frame settings, or specifying previous frame, etc has any
influence on the resultant frame sizes. The only setting that does seem to
make a big difference is the BitRate...

icecast sound compressor
...nternet to find an answers, but I didn't find anything
useful, so I'm turning to you, maybe someone has the answer.
I want to make a realtime broadcast from a Linux box. The source is the
soundcard's line-in, and it sends the stream to an Icecast server.
I would like to have realtime compressor/limiter functionalities on this
Linux box, so the outgoing signal would be of a good sound-level. The
stream would be speech mostly.
I searched with Google, but couldn't find a good solution for this exact
situation.
Can you give me a hint? What software should I use to make my plans?

icecast sound compressor
hm, to have a look at Pure Data and external called oggcast~ http://www.akustische-kunst.org/puredata/ is recomended,
you can set quality/bitrate/samplerate ... while streaming then, and do whateweryou want to your sound
before sending it to icecast, including building your compressor-limiter.
cheers

Developing SoundFont FLAC compressor using libFLAC
Its been a while since I was discussing a SoundFont compressor based on
FLAC. I've recently implemented the compressor using an application
metadata block with the ID 'SFFL' that I registered, which contains my
own header and a block of zlib (gzip) compressed SoundFont info. The
audio chunk (a block of consecutive 16 bit signed samples separated by...

benchmarking rsync's -z compression utility
Hi,
Is there a way in which rsync's -z compression (zlib) utility can be
benchmarked?
I'm trying to compare the compression ratio between rsync and external
compression tools like gzip and bzip2.
Are there any advantages to using rsync's internal compression mechanism
specified with the -z option compared to solely applying external
compression i.e. bzip2 to the files and invoking

icecast sound compressor
....
If you plan to stream in ogg vorbis, you can use Ices 2.x and accept PCM
via standard input. This means you could run a sox effect or ecasound to
get and compress the sound from the soundcard before sending it on to ices.
Ecasound can make use of LADSPA plugins which opens you to a range of
compressors, such as the SWH compressor plugins which I'm told are pretty
good.
If you want to do MP3 then I don't have any good ideas so far. Darkice
doesn't allow either receiving from standard input or inserting processing
(i.e. starting a subprocess which it sends audio to and receives au...

autocompletion: hooking ''afterUpdateElement'' in Rails
Hi everyone,
I need to trigger a Rails action after the autocompletion is completed
(when the user has selected an option).
From the scriptaculous doc, I figured out ''afterUpdateElement'' is the
place to be but I wonder if/how and where I can hook my javascript code
to this event in Rails code (I''d like to keep using the helper, if
possible)?

Google's released a high-speed x64-optimized compressor
http://code.google.com/p/snappy/
Google's methodology on this is to compress fast by taking advantage of
64-bit processing for volume, and stripping out secondary analysis for
speed. I am using tinc on a mix of 32-bit and 64-bit routers: this may be
useful for at least inter-x64 links (it will still work on 32-bit chips,
just slower).

Exact metadata reproduction
Hi! I'm just now preparing the first, still very experimental (way pre-1.0)
release of a new archival tool, similar to (and based on) zip/unzip, with the
difference that the enhanced zip tool can store x86-based decompressor code
fragments in archives along with the compressed data, which the unzip tool
runs in an isolated user-mode virtual machine in order to extract the data.
The main benefit is that the archiver can upgrade or adapt its compression
algorithms to different file types without further changing the...

OGG lossless?
Hello,
I noticed that kbps jumps quite high in -q 10 mode and is nearing lossless
compressors.
Would it be a difficult task to make OGG a lossless compressor at -q 10?
I don't know much about lossy/lossless compression internal logic, so excuse
me if my question is out of place. But this would be a really nice feature
that would make OGG an "all in one" tool.

Applying dynamic compression to live audio
...mple Plugin API (see
http://www.ladspa.org/). Basically, it was pointed out on the linux audio
dev (LAD) mailing list that numerous programs were using plugin
architectures and all were different. So they fleshed out a plugin API
and the rest, as they say, is history.
Right now, only things like compressors, expanders and limiters would
probably be useful to insert into a stream, but if someone wrote an
equaliser or a gate or something, that could well be useful too.

Load latency, file count, and a proposal
...three:
*) It lets us make the core scriptaculous files finer
grained. We can have one file per future control and
not worry about it (slider/tree/tab-pane/etc)
*) Reduced load latency
*) Easier cache management when the time comes (we
only have to manage one file in deployment)
re: javascript compressors - let''s avoid them for now
I know we talked about javascript compressors before,
but let''s not worry about them for now. Simpler is
better. Gzip''d http seems to work well enough, and if
someone wants to run a compressor on their own, they
can.
So how about it? Thoug...

Compression and saturation
Hello,
I'm not sure whether this message belongs to the "broadcast" side of
Icecast, but..
I'm broadcasting a few radio stations but I always have level
problems. Either the sound is too low, either it saturates.
There's a very fine line between the two and the broadcasters are not
always paying attention to the output level.
Some radios are on Oddcast / XP, some on
