Re: OGG music

My experiences with ogg files are always in bitrates above 192 kbs, being my favorite choice -q8 ~256 kbit/s... here is what wikipedia explain (you can check it following the URL included in my previous comment):
"Many users feel that Vorbis reaches transparency (sound quality that is indistinguishable from the original source recording) at a quality setting of -q5, approximately 160 kbit/s.[citation needed] For comparison, it is commonly felt that MP3 reaches transparency at around 192 kbit/s, resulting in larger file sizes for the same sound quality"
Anyway in sound quality there is always some personal feeling, even when sound is measures with instruments.
Personally I prefer lossless codecs (APE or FLAC) not supported by mp4 S1 MP3. So trying to reach the highest quality I tested the same songs encoded in mp3 lame@320 versus ogg from q10 to q7.
-q10 provide a bitrate ~500 kbit/s which unfortunately was badly reproduced in my MPx.
All the other level of quality were correctly reproduced being -q8 ~256 the one that provide better result considering quality and size of the file, resulting in a module 15% less than the size of mp3. Definitively this is my option for ogg encoding.
Concerning iPod, according with experts, aac is the worse encoder of this three: mp3 Lame, Ogg Vorbis and aac, however iPod users seems to be satisfied with the sound they obtain ripping their cds. Obviously what they have paid deserve to believe that, in other words, due to subjective reasons.
In any case I have no doubt of the quality in manufacture of Apple products... I just don’t want to pay them for that, especially due to all restrictions they have put in their products for commercial reasons.
I am a happy audio fan having this priceless gift given by Chinese makers: an ogg player!!! beside a good mp3 player that handles pretty well in both codecs @ 320 kbit/s
