Well, in the world of audio compression it's never boring... :-) Full press release from Dolby: http://www.aac-audio.com/press/aac.pr.0104.AACencoder.html My comments: Looks like Dolby will start licensing AAC encoder that targets consumers and the products they use like CD rippers, jukebox players, etc. Also, it looks like that this encoder will be Low Complexity AAC ("The AAC Consumer

As far as I know, LAME is able to mantain the informations stored in some audio files in the lower frequencies, useful for a Dolby pro logic decoder to reproduce a surround sound. Is ogg able to do it?

I know some floating point DSP chips use a 48 bit float internally, but if there is more than one they are unlikely to be compatible and they certainly cannot be read by standard CPUs without having pull each value apart into

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..

Hi folks, I'm trying to get a handle on the many lossless audio formats from the perspective of a software developer. I love the FLAC format because it is open source and it performs very well. But there is also the MLP (Meridian Lossless Packing), AAC (Apple Lossless), and probably some Microsoft format(s) that compete in the same feature set. These formats all achieve

Hi, As I´ve understood things, the Ogg Vorbis format supports more that two channels (stereo). Is there any tools to encode x sourcefiles into one .ogg file? I am a musican and am thrilled with the ide of makeing music in surround (or in more than stereo). This leads to my next question: is there (developing) any decoders for multichannel oggs to, let us say, 4.1 or 5.1 surround? Wouldn´t it

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.

Hi there ! I checked Vorbis' performace for mono files at approx. 64-80 kbps (it does a good job) and I'm wondering why the current OggEnc still uses Point-Stereo (>10kHz) for -q4 and -q5 I know, we're usually unable to percieve those phase correlations above 10 kHz, But a Dolby Prologic Decoder isn't. I think a future version of OggEnc which is able to use a user-selectable

Marvin, fair enough. Via's licensing terms appear to apply to encoders and decoders only, and not to transports, such as Icecast ("An AAC patent license is needed by manufacturers or developers of end-user encoder and/or decoder products"), so using Icecast to transport an AAC-encoded stream is not a violation of the AAC is not mentioned in the Icecast documentation (that I can
