Developing SoundFont FLAC compressor using libFLAC
...r. > 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. > Josh > 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 AC-0 (Y, than Cb,Cr...

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. P.S. here the regedit fix REGEDIT4 [HKEY_CLASSES_ROOT\avifile\Compressors] [HKEY_CLASSES_ROOT\avifile\Com...

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? Than...

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)? I tried passing many

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). -------------- next part -------------- An HTML

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. Cheers, Bostj...

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
