Hello, I have two questions concerning floor1 encoding/decoding. First I'll ask about the FLOOR1_fromdB_LOOKUP table: what is it's purpose? Is it to convert the amplitude differences between [floor1_Y] values to a dB scale? And, if I'm right with that, here comes the 2nd question: when render_line0 is used to encode floor1, then floor1_inverse2 must be used in decode (in order to

Lancer 20060512 (based on aoTuV 4.51) http://homepage3.nifty.com/blacksword/ Changes: * resolve resource conflict in multithread code * integrate two multithread code in mapping_forward

Hello, You know, I always worry about the precision and the float constants... and there is a large lookup table in the floor1.c ... and I figure out a way to keep the code size and speed, but to improve the precision at this lookup table. (the difference is small, but audible) Here is the modifications in the floor1.c: tatic unsigned long FLOOR_fromdB_LOOKUP[256]={

Seems we got a release candidate today. http://homepage3.nifty.com/blacksword/ And oh yeah, thanks for blocking me from participation on this list: " SMTP error from remote mailer after initial connection: host smtp.osuosl.org [140.211.166.133]: 550 Service unavailable; Client host [217.209.222.131] blocked using dynablock.njabl.org; Dynamic/Residential IP range listed by NJABL

Hi, I've found some more errors in the file format specification (or at least points, where the specification and actual libvorbis implementation mismatch): - Floor 1 / curve computation / step 1: amplitude value synthesis 21) vector [floor1_final_Y] element [i] = [predicted] - (([val] - 1) divided by 2 using integer division) hould be: 21) vector [floor1_final_Y] element [i] =

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

Hi everyone, after having an extensive look at the reference decoder as well as the specification documents, I'd like to point out what I think to be some minor omissions/flaws in the latter, and suggestions for correcting them. --- #1: in vorbis-spec-floor1.html, packet decode: Between 14) and 15) a crucial step is missing. Please insert: 14a) [cval] >>= [cbits] ---- #2: in

Is there any reason to avoid looking at optimizing the encoding process? From just a simple profile run, it looks like a big chunk of the time is in seed_curve, sqrt, dradf4 and log. Are there big changes to the encoding part that are coming that would invalidate optimizations done now? -tim --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage:

I am trying to run the program Bioedit in a Mac OS X 10.6.7. I have Wine+Winebottler 1.1.44 and Wineskin Winery 1.1. I can install Bioedit without problems, but when I try to run it this appears: Error creating object. Please verify that the Microsoft Data Access Components 2.1 (or later) have been properly installed. So I downloaded MDAC v2.81 from CNET (couldn't get it from Microsoft) and

I use Winamp v2.81 in combination with Oddcast DSP plugin. I can get the stream up and running. I also can connect to it and listen to it through another instance of Winamp. The seg fault is reproducable: 1. I

Hi, a newbie query about a potential bug in VorbisLib (I tried using bugzilla with no success): My problem is that I encountered a divide by zero exception that I tracked down to bark_noise_hybridmp() in PSY.C. I don't pretend to know what bark_noise_hybridmp() does but there are a few instances of the following in that routine: D = tN * tXX - tX * tX; R = (A + x * B) / D; When I

Hi to all of vorbis developers! I think it is time to do core optimizations to vorbis-coder/decoder in asm. I`d like to help. What you think about that?
