One thing that has always bothered me about the ogg format is the distortion of high frequency sounds - even at data rates as high 128 and 160 kbps. I find the best way around this is to resample the wav file to 48 kHz (using SoundForge 6.0) before encoding (using CDex) to ogg. It takes a while, and adds a lot of extra wear and tear on my drive, but what a difference! The result is an 80k ogg file that sounds EVERY BIT as good as 128k MP3 at less than two thirds the size! http://www.subgenius.com/ts/hos.html I don't get the same result when I set the sampling rate on OggDropXPd to 48 kHz. Why is that? This is quite different from MP3 encoding, where the data rate seems to make the biggest difference in sound quality). Why is this? Is anyone else resampling their wav's/aiff's before encoding to ogg? Is there an easier way to achieve the same result? db __________________________________ Do you Yahoo!? Yahoo!

I think, this process will actually work more or less like a lowpass filter :) -- /dev/brains: permission denied Please avoid sending me Word or PowerPoint attachments.

You don´t have one of those cards have you?
