Specification change requests
Hi, as Conrad suggested, I've made a complete list of all points in the specification, which I beleive are errors, or where the explanation is unclear, contains unneccessary steps and so on. I hope someone has time to look through the points and if and when accepting or rejecting them be so very kind and inform me about it. I will also once again try to work through the residue

Floor type 0 and residues type 0 and 1
Hi, it seems to me as if all vorbis-files only contain floors of type 1 and residues of type 2. Is it possible to "force" the encoder to somehow create a vorbis-file with the other floor and residue types?

Flash Vorbis player
Hi, I wanted to let you know that I have just made available the sources to the ogg + vorbis implementation in haXe, which I've been working on for last couple of weeks. The code compiles to an swf file playable in Flash Player 10. A demo of a simple player implementation (latest Flash 10 required): http://people.xiph.org/~arek/pg/hx/test.html and the sources, in a bzr branch, currently

high frequencies response
Hi there In the past, i have used lame to encode high quality mp3-files (vbr 1, bitrate ~ 192kbit). I tend to switch to ogg with Quality 4 or 5, but i noticed, that many ogg-files tend to produce too much high frequencies response. In many cases, this is very noticeable. For my opinion, i cannot accept this worse frequence reponse. I have used latest version of ogg (OggEnc v1.0, precompiled

Me, the grouser?
Hi everyone, after attempting to correct Ivo's statement about Theora and Vorbis being the "default codecs" in the HTML 5 draft, I just got the following mail off list: "Why are you still here?

My Flash 10 attempt
Hi everybody, after hearing about the new Sound functionality in Flash 10, Arek's performance gain using the new Vector type instead of Array and not at least actually seeing the performance boost he achieved compared to my old Vorbis decoder, I found a few hours yesterday to migrate my old code. First of all: the new PCM playback API for Flash is rather restricted and only allows 44.1

Support for ultra-high sample rates?
Isn't the FLAC encoder 'tuned' for the compression of audio data at common sample rates anyway? Does it make sense to use FLAC to compress arbitrary analog data at very high sample rates as opposed to other general purpose compression algorithms?

Flac multi channel
I see :( That what I would call a good struct size optimisation. Please tell me there was another reason behind this being only 3 instead of 8 or 16 bits, right ? 2017-01-25 18:30 GMT+01:00 Tor-Einar Jarnbjo <tor-einar at jarnbjo.name>: > Hello Olivier, > > the limitation is in the file format itself, as the number of channels is > encoded in a 3 bit field in the streaminfo

Confusion with page_segments / segment_table
Hi, There is something I don't understand about the page_segment and segment_table values in the documentation. As I understand it, the segment table consist of as many bytes as specified in page_segment, PLUS one trailing byte with a value between 0 and 254. I've looked at some files that has a Comment tag so large, that it is spread over two pages. Here, the first Page Header (not the

Flac multi channel
Hi Guys, I know that FLAC format is currently limited to 8 channels but I was wondering if this hard limitation of the format or if it can be easily circumvented if the flac library is compiled with other settings and/or the software using it don't mind it Thanks ! -- Olivier Tristan Research & Development www.uvi.net
