Hello! I am about to buy a new computer, and because encoding/decoding .ogg files is the most processor intensive thing I intend to regularly do, I would like to know which is the "recommended" processor for real-time encoding (I record my favourite radio shows). TIA! Bye, Joane Lispton PS: I receive the FM radio stations through my cable (the one which brings me cable TV), which has a _really_ good sound quality, which I would like to preserve. So I wish to do real-time encoding in a way that isn't too lossy (perhaps the one used when reading from CDs? or is that an overkill?); is this possible on regular (non-SMP) PCs? I never used Ogg Vorbis before... _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com. --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a message to 'vorbis-request@xiph.org' containing only the word 'unsubscribe' in the body.

Joane, I have a P3 866 MHz at home and with that I am able to both RIP and ENCODE a CD using the LAME VBR MP3 encoder in about 50% of the time required to actually play the CD (i.e. if a CD is 60 min long, I can usually both rip and encode it in under 30 min). So, my guess is that any P3 with enough RAM should be more than enough for real-time encoding, both under MP3 and Ogg Vorbis (not sure if the ogg encoder is as optimized speedwise as LAME recently). Good luck, Jacek -----Original Message----- From: Joane Lispton [mailto:jlispton@hotmail.com] Sent: Tue/mm/2001 12:12 PM To: vorbis@xiph.org Subject: [vorbis] Choosing a processor Hello!

Oops...

Well no, I don't do that, I just did it as a point to illustrate that today's computer speeds should be more than adequate to do real-time encoding. I use W2K, so I can't comment on Linux-specific software, but without the overhead of X-Windows (since you seem to be running everything in command line) then you should get an even faster encoding time. I can't help you though with any software on Linux that can do any real-time encoding of audio streams. I'm sure they have something on freshmeat under the MP3/Ogg section.

All depends on the quality of the CD drive and how flawless you want the rip to be. I have a generic LG (not a high-end plextor) and I only rip using EAC (similar to cdparanoia under Linux) which just re-reads sectors endlessly until it's 100% sure it has a good rip. With just a standard CD ripper I could probably rip at 14x too, but then I'd have to deal with all the skips and errors that can occur because of this. Nothing more frustrating than burning a CD of MP3s and finding out later you have to re-rip, re-encode and re-burn again because of potentially faulty CD rips.

Exactly. Ripping a CD can cause problems you wouldn't get if you were just listening to it. Fortunately for Win32 users EAC handles it nearly flawlessly and Linux users have had the cdparanoia package for a while now (emusic.com uses it internally to make sure all the MP3 albums they offer for sale are ripped at the best possible quality) Jacek -----Original Message----- From: David Mitchell [mailto:mitchell@ucar.edu] Sent: Tue/mm/2001 4:32 PM To: vorbis@xiph.org Subject: Re: [vorbis] Choosing a processor Rosyna wrote:> > Wow, then you must have a REALLY hard time listening to cds if all cd > players you use have to do massive error checking.You should check out the CDParanoia FAQ.

Lucky you, I've had plenty, especially on scratched, older CDs.
