OMG .ogg voribs is not goot it's the BEST



 Here is why you should be using .OGG voribs/theora format instead of mp3,wma ..etc

When i first read about the .ogg & voribs  (1 year back) i was really excited about it ( taking into account that i already was a fan of open software)
but i did not do much about it, just tried converting some .mp3s to OGG to see if the file size reduced, at times it did and sometimes it did not, just like what happen when someone diet and instead of loosing they gain.

It was 1 week before that i really took a look at it carefully when i was in a situation were i wanted a audio file to be converted into the elast possible size but with minimum quality loss.
like a parrot that is trained to repeat what is said ,my grey cells cried immediately Mp3 ..Mp3.. Mp3..
and i set to work, I took a 1minute (1.8MB 128kbps) file so i could test it before i do the complete conversion.

I started of encoding and i slowly discovered something great.

below is the conditions and properties of each file.

FORMAT|   BITRATE|     SIZE|  QUALITY

MP3                128           1.8MB   GOOD
MP3                64             820KB    POOR
MP3                 32           430KB    CRAP


the dip in quality was unbearable, even the voice was getting affected in such a way that its tone and pitch changed to and extend that you immediately notice.

Then i notice the option .OGG in my encoder , so i selected it and redid the entire process and guess what i got results that were from other planets.

below is the conditions and properties of each file.

FORMAT|   BITRATE|     SIZE|  QUALITY
OGG                128           1.2MB   GREAT
OGG                64             534KB   GREAT
OGG                 32            230KB    GOOD

the bit rate virtualy made no difference to the sound quality.
i had to listen to the 32 bit version and 128 bit version alternatively 3 time to feel the minute change that had occurd (i used audacity to analyze it). This siomply means there was no noticable change to quality that can be identified by human analysis easily.

i have no extra words but to request all of you to start using .OGG voribs format for your media ( both audio and video). because it's free and simply awsome in all sense.
I guarentee that you will never will be dissapointed by it.
and firefox 3 and up have inbuilt support for OGG media.


here is a good encoder to convert your media to .OGG = http://www.ogg-converter.com/

VLC Player is the best player that supports .OGG in my opinion
