Oversimplified usage listing of mp3 and wma compressions
Here is a oversimplified listing of the MP3 compressions :Notice that as the number in the left pane is higher , the higher the filter and thus higher fidelity audio. The higher numbers can offer the abilities or the lower numbers too.
Notice: The program used is Music match jukebox that offers the curves shown in http://zlgr.multiply.com/reviews/item/22

And notice the following:
The above listing is still controversial and depends on the program and codecs you use. Older lame codec [used in goldwave ] does not offer the same audio quality
and several comments on windows media wma files:
- offering lower dynamic range : they can clip very low voices
- on hardware players :
- they can drain the double current .
- in most older MP3 players i tested , the WMA codec can offer better audio than its MP3 codec||
- the wma codec may introduce its own noise with 'cracks' in sudden audio changes or in loud points.
