Hello all I have been encoding to OGG as a default for well over a year, but I recently thought I ought to test how it sounds compared to other codecs. I got the Windows Media 9 encoder and I was quite surprised at how bad a job OGG did at quality 0 with a simple piano clip, and how well WMA9 was - I've always considered WMA as being a bit naff, but WMA9 has forced me to re-access this view Drop by http://www.tompagenet.co.uk/vorbis/ to see if you agree or can offer any insight - shouldn't OGG beat WMA9 in sound quality? The original is from the Lost in Translation sound track - please don't download it too much - I do have limited bandwidth!

I wish oggenc automatically did things like this given a target bitrate, but oh well. And there may be other tunings I don't know about. -- Tom Felker, <tcfelker@mtco.com> <http://vlevel.sourceforge.net> - Stop fiddling with the volume knob. "Outlook not so good."

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 After listening to both files, I find that the Ogg file swishes a little, which is not unlike what I expected it to do. I found, however, that the WMA file has a serious ringing problem. I especially noticed this ringing in the ocean waves. It sounded like an old tape that is rubbing hard against the head of the tape player and is squeaking in the speaker. I know that WMA rings, but the ringing was unusually loud in this recording. In short, I will take a soft swish over a loud squeaky ring any day.

That said, I agree with Lorenzo that the ringing/twinkling artifacts in the wma version are far more intrusive than the swishing produced by vorbis sounds pretty much like the swishing of the waves anyway. The -q4 --resample 22500 version is ok, but I don't like the loss of attack that you get at that sample rate.

You might want to go over to HydrogenAudio.org and look around for some discussions about a couple of alternative tuned versions of Vorbis. (I'd give you the links, but I don't have them. I haven't been concerned about low bit rates. I just see the message threads occasionally.) Everybody knows of Garf's higher tunings, but in the past few months, there have actually been some other people trying to tune Vorbis for the lower ranges too. WMA 9 has improved, and WMA 9 PRO is supposedly much better. (They gave up compatability with regular WMA.) But considering how many people are anti-microsoft, you might want to be careful saying anything good about their products...[grin] ----- Original Message ----- From: "Tom Page" <t.a.page@durham.ac.uk> To: <vorbis@xiph.org> Sent: Friday, February 27, 2004 6:51 PM Subject: [vorbis] WMA9 versus OGG <p>> Hello all> > I have been encoding to OGG as a default for well over a year, but I > recently thought I ought to test how it sounds compared to other codecs.
