Comparing WMA10 Pro formats at middle-high and high bit rates(96Kbps-256Kbps)

In the last article (see http://jilluh.blogspot.com/2007/10/amazing-test-mp3oggwma10-pro-format.html), I’ve compared Mp3, OGG and WMA10 Pro formats at low bit rates---64kbps that the WMA10 Pro (64kbps) reached an amazing high level (almost over 21000HZ) nearly to normal CD audio quality.

But this time I have tried to transfer the original file into WMA10 Pro formats with different profiles in order to see that if WMA10 Pro codes also have high music performance at middle-high and high bit rates.








Conclusions:

1.WMA10 Pro CBR 96Kbps has a very nice frequency spectrum as well as WMA10 Pro CBR 64Kbps. Its figure looks quite similar to the WMA10 Pro CBR 192Kbps,actually it's even a little bit better, e.g., it provides high quality of music with smaller size. No doubt, it's a very good choice for streaming media.

2. The performance of WMA10 Pro 128Kbps and WMA10 Pro 160Kbps are obviously pretty disappointing, their highest frequencies are even much lower than WMA10 Pro 96Kbps, although the WMA10 Pro 256Kbps shows a great spectrum as the original(its size might not be satisfied).

3. Eventually we can call WMA10 Pro----the killer at lower bit rates instead of Ogg, that is, of course, questionless.
