btw: will 1.1 contain the changes of garf or will the GT versions stay GT versions and the changes are not going to be implemented into 1.1 ?

Will the sources of GT3 be available at some time and will you try to commit the changes to the official sources when they proove stable?

When I'm satisfied with quality, the changes will go to Monty. I've uploaded the Linux binary.

I wonder if Garf is getting upset at us muppets not reading the whole thread?

Something that I noticed when you encode a track that has a long silence (say a silence between a track and a hidden track many minutes later) Winamp reports that the bit rate while recording the silence is approximately 152kbs.  Is that something to do with GT3 or Winamp?

Neither. It's something to do with your track. It isn't quite silence; it's very quiet noise. Noise is usually harder to encode than music, so vorbis throws a lot of bits at it to try to reproduce your noise as accurately as possible.

If you run a noise gate over the .wav before encoding it, vorbis will encode the digital silence at 1 kbps or so.

huh, i got you thanks, tried it with a few others (OGG 1.0, MPC, -aps) and they all didn't go to there lowest bitrate, there must be something there (noise) then... thanks

What is this noise gate about? I tried searching for it, but it doesn't seem to be known on this forum. Where can I get this noise gate and how to use it?
I think it might be usefull for encoding the sound of movies.

A gate is an electronic (digital/analog/whatever) audio circuit that turns down the output gain when the input signal falls below a certain threshold.

Basic controls you want to look for to tweak and really get the hang of what a Gate can do for ya, look for:  Threshold, Ratio or Gain Reduction (in db), Attack, and Release.

Where can you get a gate?  Like, for what?  Hardware?  Software?  What software?  hehe      PM me or start a new thread.

I have a few questions about the GT3b1.

First, I noticed the filesize for the .exe is 166kb.  Now the .exe for 1.0 shows up as 1.01mb.  Is this correct?  And if so what accounts for this tuned version being so much smaller?

Second, is there anyway to pause the text output of the "-h" commandline to see all text?  I'm using it in a dos box under WinME and all the old dos commands I could remember wouldn't stop it from just scrolling all the way to the end.  I just wanted to see if there was any difference between the information there and on the dos version of 1.0.

[Edit]
Or is there a manual for GT3b1 that I missed?  The only thing I downloaded was OggEncGT3b1.exe.  Was I supposed to get it somewhere else with an accompanying help file?

The .exe is compressed.

try oggencgt3b1 | more

There's no manual.

Alright the |more command worked, thanks Garf.

I successfully encoded two files with the -q 6  switch.  Then I realized I forgot to add a padding for the tag so I went back and tried it again with -q 6 -p 4.  Immediately upon attempting to encode I get an error and program close.  I tried again using JUST the -p 4 switch without setting the quality and it encodes perfectly fine...  Then I tried again using -p 4 -q 6 to see if the order had anything to do with it and this once again it produces the error.  Why am I unable to use the two switches in conjunction?  Should I just take the time to write out a long command line that includes the tagging information to avoid this?

I'd like to warn everyone from using the Octimax plugin for Winamp with OGG files.  I thought my files were corrupted but for some reason Octimax was turning EVERYTHING into pure noise.  I'm going to check back at their site to see what is up with this.

I searched the forum, but found nothing that could help me, so if this question has already been asked thousands of times please don't get upset.

Is it possible to encode an entire folder with .flac or .wav files to gt3b1 files with one single command? I tried to encode with "oggencgt3b1 -q 6 "*.wav"" but it didn't work. Up to now I used to type every single file name to encode and that really s***s. 

Help will be appreciated .
I love the moderators.

To encode all wavs to q6:

FOR %f IN (*.wav) DO oggenc -q6 "%f"

To decode flacs, then encode to q6

FOR %f IN (*.flac) DO flac -d "%f"
FOR %f IN (*.wav) DO oggenc -q6 "%f"

It has been a while so I hope this is the correct code. There is no sense in waiting for a final GT3, there will probably never be any, as I do not have sufficient time to work on it.

Thanks a lot, Garf.  Time to go to work!!

OK, for those whose appetite is so whetted that they can wait no longer, I've just uploaded oggdropXPdV1.7Gt3b1 to the Ogg Vorbis page at Rarewares.  Further compiles will follow, this is just to keep you going for the time being!!

Garf,

I totally respect your freedom to spend your time as you wish, rather than as we'd all like  I just wondered if there is any plan to include some of your work in the the mainstream vorbis encoder - it seems a shame to lose the effort, but I imagine it's not just a copy and paste exercise either!

Cheers, Paul

Standard (ie., not P4) versions of oggenc2.2, oggencFLAC and oggenc-unicode all compiled with Garf's GT3b1 libs now uploaded and available at Rarewares.

So who will continue work on Ogg Vorbis? Noone? Where are guys from Xiph? How much Ogg Vorbis can be improved from GT3b1?

EDIT:
I hope that Garf tunings will be added to latest CVS
OR
Changes between 17.07.2002 and latest CVS will be added to Garfs version.
AND
result will be posted as official, latest code.

I think it will be very close, but for example floggy has problems, so you can't release it in the official code.

I overheard Monty say that they plan to do more work on the encoder, to keep Vorbis ahead of latest developments such as AAC+SBR. I don't know about any high bitrate work - it doesn't seem to be a priority. Merging the high bitrate tweaks is fairly easy (they are extremely simple, I had no time to do more!) but floggy needs work to be stable (and the tweaks are a lot more complex).

The problem is that Xiph is horribly understaffed at least as far as work on Vorbis goes.

I know a standard Ogg vorbis encoder exists, and a version optimised for high bit rates (GT3).  I am sure I read somewhere that another version exists which is optimised for low bit rates.

So my question is, is any one planning on making a version which includes all 3 of the above, i.e. Ogg Vorbis Ultra

That was probably floggy, it's included in gt3b1.
