How to interpret codec test

(1/1)

nalazord:
I done codec performance comparison and I don't know how to interpret this results.
Which codec is the best for lossy format and which bitrate. If this help, my music player is Sansa Clip+.

saratoga:
MHz is how many MHz are needed to decode the file at 1.0x real time.

nalazord:
So, If we don't take into consideration little outdated codecs like MP1 or MP2, the best, lossy codec, will be the Musepack, yes?

Musepack looks quite good in those results, yes, although mp3 isn't far off. For the best bitrate, I suspect you'll have to decide for yourself, possibly using ABX testing for best results.
