Hey Guys,
I am impressed with OggPlay application. Currently I use it to play MP3s on my 6630. I tried converting MP3 to OGG once (using some Ogg Converter) but I din't see any noticable file size difference. Since then, I am sticking to MP3s, which I can play using RealPlayer as well OggPlayer and also can set as ringtones. Can you tell me, guys a best Ogg converter and best settings to convert MP3 to Ogg without losing any quality and saving noticable amount of space.. Please do guide me !!

As far as I know, just decrease the Bit Rate while converting until you get the best quality over size performance.

Search this forum looking for db poweramp it will give you the links & instructions you need. I use to convert all my mp3 to ogg
Id post the link myself but I'm a newbie & don't know how(blonde you see)

Basically, when encoding from an uncompressed source, general concensus is that an Ogg file at 64Kbit/s is equivalent in quality to an mp3 at 128Kbit/s.

You'll obviously lose a certain amount of quality when transcoding from mp3 to Ogg, as with any lossy-to-lossy recompression, but the degradation is minimal and mostly unnoticeable.
