CBR audio

[leadman584]

Ok, so I've been encoding vidoes since June, over 100 encodes done. The video quality continues to improve, usually looks better than original DVDs. Unfortunately the sound quality continues to suck. I use GKnot, but the VBR audio from BeSweet crashes all of my computers. When I use VDub to re-encode to a CBR audio the best I can get is 64kbs@24khz. This could easily be a fault in my system configuration. I have changed the acm in my system.ini to l3codecp.acm. I'm no programmer(nowhere close, just a regular joe). I would like to find a setting for Besweet or any audio encoder to transcode AC3 to 128kbs@48Khz cbr mp3. I'd even be happier if I could add a lowpass filter set between 16 and 19.5Khz
I have already tried adding wav header to a VBR mp3, no joy.
AZID to wav in BeSweet, no joy. (actually get a tone file, no audio)
Truth be told, I need a configuration that produces a usable file in GKnot. I want to get some of my friends involved in encoding videos to help improve my own library, and theyre's as well.
Dvdx had no problems encoding video with great sound. Unfortunately you had to be there to initiate second pass for video. I work in a factory(slave labor) and want to set it and forget it in GKnot, but I need CBR settings for audio. Come home to a brand spankin new avi ready to put to disc. Maybe this is a pipe dream. but the great DSPGuru(who wrote this program, Besweet I mean) frequents this site, maybe, hope upon hope, he could devise a preset for Besweet to do a CBR mp3. Please, if anyone knows haw to do this, I am open to any ideas:)

It sounds to me like you need to spend some time reading the guides. I'm not sure why you are having problems with gknot, and for sure you can use bewseet to make CBR mp3s. Have a look at the guides.

Try doing the audio manualy with besweet and besweet gui, chck out http://dspguru.doom9.org.

If you cant do better than 64kbps in vdub then that sounds to me like you dont have the radium or LAME codecs installed properly, again have a look through the FAQs and guides.

Stick with it, you can get very good results from gknot and besweet. but don't use 128kbps AC3! Thats a way too low bitrate for a 5.1 ac3 track!

Thanks for the word. I got a similar reply at Divx forum. I have installed the radium codec, and removed l3codeca.acm and l3codecx.acm from system file. VDub still fails to compress above 64kbs. Gonna dump everything in Gknot folder, clean registry, and try fresh reinstall of entire program. Since I had this problem prior to installing P4 version of VDub, should be safe to upgrade to it in Gknot. Thanx again for the helpful advice.

Or do as I always do: I always encode audio separately in RazorLame, then mux it with the Video in NanDub.

This in 2 steps:
1) Convert the AC3 to WAV using AZID in a DOS command:
azid -c normal -a filename.ac3 filename.wav
You can add "-F wav24" if you want better quality.
Add "-L -3db" if you have a 5.1 source.
2) Convert the WAV to MP3 (CBR or VBR, as you like) in RazorLame.

If you want to mux a CBR MP3 with your soundless AVI, you can also use VirtualDub. Just be sure to fake wave the MP3 using WAVEMP3, so you can load it in VirtualDub.

BTW, don't forget the delay!

Ok, looks like a system configuration problem.
So far, I've used BeSweet to make a standard wav and muxed to soundless movie_avi file created by GKnot. Can't convert sound above 64Kbs@24Khz in VDub.
Created CBR mp3 in besweet using lame. Added wav header with Wavmp3. muxed to quiet avi. Crashes in playback the second I scroll forward in movie with Divx Player or WMP.
I've used BeSweet and Headache to extract straight wav from AC3. used both CDex and Razorlame to encode to MP3 CBR. Winamp says RazorLame version is still VBR, but anyways added wav header to all 4 of these attempts. All 4 crash my players when muxed back to movie_avi files, and attempt to scroll through movie.
In desperation uninstalled entire GKnot and all associated files.
Hunted down all files containing text for any of the GKnot used programs. Used JV16 to remove all orphan registry keys. System.ini using only l3codecp.acm. deleted l3codeca.acm and l3codecx.acm from system file. Insured radium hack recognized in Multimedia, audio codecs.
Completely reinstalled GKnot .21, then .26, and .26 patch. Replaced Besweet, VDub, and Nandub with current versions. Including latest stable BeSweet GUI.
Repeated all of the previous audio attempts plus anything else suggested on this and Divx forums. All attempts crash player when I try to scroll forward in a movie.
Perhaps there is a file on my system somewhere that is holding a preset for VDub or Nandub that still use some sort of codec that prevents audio compression in VDub above 24khz? I am using ME for my OS, maybe this prevents me from using higher codecs? Any other Ideas would be appreciated. Or I may be stuck with what I have.
