Hello all, I wanted to ask some experienced users some settings about oggenc. 1. How can I setup oggenc so that I can DIRECTLY rip tracks off my audio cd? As we all know, audio cd doens't really have a file format that we can directly use. Do I HAVE to convert them to wav files then convert them to ogg files? 2. The options: -b -m -M with the bitrate of the audio file. If I set something with the '-b' option and also use the '-m' and '-M' option, for example 'oggenc -b 128 -m 64 -M 128 file.wav', how is this effected? Furthermore, how does the '-q' option come into role here? It says that it ranges from 0 to 10. I'm assuming that this is a preset quality controller that we can use to replace using the other three options that I previously mentioned. Is my assumption correct? All help is greatly appreciated. bp _________________________________________________________________ Protect your PC - get McAfee.com VirusScan Online clinic.mcafee.com/clinic/ibuy/campaign.asp?cid=3963 --- >8 ---- List archives: xiph.org/archives Ogg project homepage: xiph.org/ogg To unsubscribe from this list, send a message to 'vorbis-request@xiph.org' containing only the word 'unsubscribe' in the body.

Is my assumption correct?If you're using Linux or a UNIX flavor, try xmcd ( amb.org/xmcd ). Xmcd can rip CDs directly into a number of formats, including Ogg Vorbis. Since xmcd links with libvorbisenc, libvorbis and libogg and makes direct calls into them, it doesn't even need oggenc. -Ti -- /// Ti Kan Vorsprung durch Technik /// AMB Laboratories, Sunnyvale, CA.

I usually rip to WAV, then compress to mp3/ogg, and archive the WAV as a FLAC file. I run it as a batch, so that I can rip a few cds, start eh compression, and walk away.> directly use. Do I HAVE to convert them to wav files then convert them to > ogg files?I think that some programs will still rip to WAV, then compress that file. Others may just pipe the source data through the compressor. I don't use it this way, so I don't know. -B -- Brandon High armitage@freaks.com '98 Kawi ZX-7R "Wasabi", '98 Kawi EX500 "Harlot", '02 BMW R1150RS "Troll" The only thing wrong with a perfect drive to work is that you end up at work. --- >8 ---- List archives: xiph.org/archives Ogg project homepage: xiph.org/ogg To unsubscribe from this list, send a message to 'vorbis-request@xiph.org' containing only the word 'unsubscribe' in the body.

If you're in Windows you'll want to use EAC or CDex, since they both support "on-the-fly" Ogg Vorbis encoding. You can find links for downloading these "rippers" at ogghelp.com: ogghelp.com/ogg/downloads.cfm Under Linux, there's a way to feed oggenc directly from a pipe from cdparanoia.> 2.

Ogg Vorbis is natively a VBR format, and thus specifying a specific bitrate forces it into a pseudo-CBR mode, which will *always* produce worse-sounding files at a given filesize.> Furthermore, how does the '-q' option come into role here? It says that it > ranges from 0 to 10. I'm assuming that this is a preset quality controller > that we can use to replace using the other three options that I previously > mentioned. Is my assumption correct?Yes, but unless you have very specific maximum bitrate needs (i.e. streaming to modem users), you should ALWAYS use -q alone and NEVER use -b, -m or -M. In case you're curious, here are the average bitrates for each quality level, but keep in mind that the actual bitrate for a given quality level varies depending on the input file. Also, note that these are simply estimates, oggenc doesn't actually aim at a specific bitrate at all. The quality setting is a measure of "closeness to the original" which is used internally, and the resulting bitrate (whatever it ends up being) is a byproduct of that. Quality -1 ~48 kbps Quality 0 ~64 kbps Quality 1 ~80 kbps Quality 2 ~96 kbps Quality 3 ~112 kbps Quality 4 ~128 kbps Quality 5 ~160 kbps Quality 6 ~192 kbps Quality 7 ~224 kbps ...etc Quality 10 ~498! kbps For more clarification on this you might want to read the section on "CBR? VBR? ABR?" and the following section on "Just Say No To Bitrates" in the Introduction to Compressed Audio with Ogg Vorbis (by yours truly) at: grahammitchell.com/writings/vorbis_intro.html -- Graham Mitchell - computer science teacher, Leander High School "There has grown up in the minds of certain groups in this country the notion that because a man or corporation has made a profit out of the public for a number of years, the government and the courts are charged with the duty of guaranteeing such profit in the future, even in the face of changing circumstances and contrary to public interest. This strange doctrine is not supported by statute or common law. Neither individuals nor corporations have any right to come into court and ask that the clock of history be stopped, or turned back." -- Robert Heinlein, "Life-Line" --- >8 ---- List archives: xiph.org/archives Ogg project homepage: xiph.org/ogg To unsubscribe from this list, send a message to 'vorbis-request@xiph.org' containing only the word 'unsubscribe' in the body.

To set it to rip Ogg Vorbis files goto the Options menu and choose Settings. Then goto the Encoder tab and choose Ogg Vorbis DLL Encoder from the drop down list. Under Encoder Options be sure that On the fly Encoding is checked. For bitrate settings refer to the next answer. If you want skip corrention turned on then goto the CD Drive tab and select Paranoia, Full under the ripping method drop down menu(this will make ripping non-scratched CDs a little slower though, but not much). To select your destination directory goto the Filenames tab(click the ? button for help). If you use CDDB(or equivilent service) then CDex will automaticly add tags to your files.> 2.

Is my assumption correct?First: -b128 means that it should encode as close as it can to 128 kbps. -m means that it should use at least 64 kbps and -M means that it shouldn't go over 128 kbps. -q is preferred to all of the above because it uses as much or as little as it needs to achive the quality setting you select(for example: when I ripped the soundtrack for Half-Life at Quality 5(-q 5) the bitrates ranged from 112 kbps to 224 kbps). And Ogg Vorbis isn't just limited to useing birates that are multiples of 16: it can use any bitrate at all(unlike MP3). -q 3 is the default for oggenc(and other Vorbis encoders) and achives around 128kbps MP3 quality. Experiment with different quality settings to see which is a good balance of file size and audio quality. I would recomend you read the Vorbis FAQ(vorbis.com/faq.psp) for more info on bitrates and sound quality. --- >8 ---- List archives: xiph.org/archives Ogg project homepage: xiph.org/ogg To unsubscribe from this list, send a message to 'vorbis-request@xiph.org' containing only the word 'unsubscribe' in the body.

Actually, audio CD's do have a file format. Each track is burned as a *.cda file. There are restrictions on publishing/disclosing the format in order to discourage piracy and copyright violations. If oggenc does not recognize the .cda then ripping to .wav with another tool and then encoding should work...
