AAC Plus at 32kbps with Parametric Stereo
AAC Plus at 32kbps, without Parametric Stereo
MP3 Lame -Presets
[WARNING : Due to the nature of my test sample and the variable bitrate of Lame these sample do not show Lame's full potential, the average bitrate is a lot lower than a real life music file.]
MP3 Lame 3.97 --preset fast standard ( ~ 130kbps )
MP3 Lame 3.97 --preset fast extreme (~ 148kbps)
..As you can see the 32kbps AAC+ is quite nice for only 32kbps (except that its doing some crazy "copy-paste" thing at the high-tone sweeps in the beginning, compare it to the MP3's below it), still its inferiour to the 96kbp normal AAC. I can imagine that AAC+ will (or is) be very populair with low-bandwith Internet Radio Stations.
About the Lame Presets, they are better than my results with the CBR settings posted on the first page at higher bitrates, the bitrates are lower then in a real music file, however it still shows that VBR is better than CBR.
