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

Specification documents
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.

Floor1 encode/decode and FLOOR1_fromdB_LOOKUP
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

FLOOR_fromdB_LOOKUP
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]={

How floor1 modifications may affect final (de)coded samples?
Hello, I've been "playing" a little with the floor1 encoding, and my game has posed me a question. I've been modifying (just curiosity) manually, and randomly (not too great modifications), the quantized [floor1_Y] values, just before coding them with the codebooks. As, if I'm not wrong, the [floor1_Y] obtained are then removed to get the residue vectors for each channel, I

Master user
Hi, I'd like to have a master user that can read the other users mailboxes. I have only one user who read and write the mail (i.e. I use the static userdb) and I use namespace for public and shared mailboxes. I can authenticate to the server but I am not able to list the mailboxes: > emiliano at dovecot:~$ telnet localhost imap > Trying 127.0.0.1... > Connected to localhost. >

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?

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

GSSAPI vs group check
Dear All, Is it possible to make any authorization (eg. checking of group membership) in case of GSSAPI authentication? Our dovecot authenticates the users against PAM and GSSAPI. In the PAM file I'm able to check if a user is a member of a selected (e.g mailreader) group. If the user is member, he can login otherwise not (see below). If the user has a valid Kerberos ticket and he

Test files for decoder implementation
Hi, I am trying to implement a Vorbis decoder in Java, and I have some problems understanding the file-format specification included with libvorbis. In the header description, there are a few obvious mistakes, which I believe to have solved, but when I try to decode the audio packets, the decoded floor and residue data doesn't seem to make sense at all, and after a few packets, my decoder

GSSAPI vs group check
Dear All, We are having a very similar issue with dovecot 2.2.34 as ?kos. We want our users to authenticate via GSSAPI over Kerberos using their TGT. Our setup is two distinct locations with their own dovecot's with access to these being handled via LDAP auth mechanism with filters to check for their group memberships, i.e. users from location A are in group A and users from location B
