similar to: Why so many lossless formats?

Oops, I was a bit sloppy in my organization, and also sloppy on a few facts. I did not intend to imply that A-52 was lossless - I was merely using it as an example of an open specification format that cannot be implemented and sold without being licensed. I'm glad that we are finally getting lossless formats accepted in large public standards. The liba52 library may not be legal. I

First off, I'm not an expert in this field, but I thought I could probably answer a few of your questions. If anyone else wants to give a more complete explanation, please do.

Hello to the list, and please forgive me if this has already been asked before. (I am new here, you see) The question is really simple: Can I use FLAC to create multichannel files, ranging from 3-channel LCR, through Quad, 4.1 to 5.1 and possibly (later) above? The projects details are essentially this: DVD-Audio, containing MLP Lossless in stereo & surround/multichannel. Video_TS folder

http://mp3licensing.com/other/index.html They list: Atrac 3, (E)Pac, AAC ..and various patents of theirs they believe that these formats rely on.. then basically say: "We have not yet determined our licensing policy for this format" Vorbis is not mentioned..

Fraunhofer Institute for Integrated Circuits has stopped providing licenses for MP3 technology, "[...] noting that more superior audio formats have rendered the MP3 obsolete. Speaking to National Public Radio (USA), the Fraunhofer Institute said AAC has since become the 'de facto standard for music download and videos on mobile phones.' "

After reading http://mp3.radified.com/mp3.htm I sent Rad an explanation of some things as I understand them. He liked it and posted it on his site (still unlinked, use the URL below). Can somebody with better understanding of psycho-acoustic terms and the vorbis model check it and comment on it? In particular I didn't know how vorbis handles quantization noise. If you reply with

I know this probably transcends the scope of the current aims of Ogg video, but one thing I'd consider extremely useful is a lossless video compressor. There are a few of them out there (e.g. PICVideo's lossless wavelet codec) but I've found no free ones so far. The primary use would be for storage of video clips that would be too cumbersome to store as raw frames but still require

It's really pretty simple. You can download the code and build it all you want... ...for yourself. It cannot be distributed, sold, or used commercially in any way.

All, Progress has been made on the proposed draft spec for integrating ambisonics into vorbis. We are not yet finished (should be soon), but you can see the progress here: http://docs.google.com/Doc?id=df4dtw69_3626qqq6st The issue we have hit now concerns how/who would implement the encoding and decoding in Vorbis Tools. Because ambisonics uses spherical harmonic components, an ambisonic file

I recall reading that all MPEG AAC software has different and incompatible file formats , because this is a condition set by the MPEG AAC technology licensing authority. Some kind of yet-another-anti-piracy-measure, the idea probably being that users of different software can not swap their files. I picked up this a while ago when following AAC software development, but can't remember exactly

Hi, I am wondering how to add AAC support to GStreamer's shout2send element. Support for this format seems to be enabled in icecast for a while and it would be nice if one of the major open source frameworks would have been capable of streaming such content. GStreamer's shout2send relies on the libshout library but it defines only two formats - MP3 and Vorbis. There is no single word in

Hello all, I would like to know what kind of AAC can stream icecast 2.2.0. Is it MPEG-2 AAC or MPEG-4 AAC? How much efficiency can be gained by using this kind of AAC compared to MP3? -------------- next part -------------- An HTML attachment was scrubbed...

It obviously would be nice to have such a mode available, for e.g. DVD audio compression. Apparently, the list doesn''t tell me too much about it. My questions are: 1. What is the current status of the 5.1 channel coupling in Vorbis? 2. If I''ll be interested in participation in its development, what is the recommended reading? -------------- next part -------------- An HTML

We've been using Icecast KH for years now with great success. Thanks again Karl H! It's past time to ditch Flash! I'm probably a bit out of date on this issue. The last time I checked, no browser was able to directly play an AAC / MP4 / M4A stream from Icecast. They can play AAC _files_ but not _streams_. I see that there are now alternatives beyond Wowza and Red5. But my
