... I know it's lossless. And I didn't mean anything negative from that previous post, I'm sure you know enough not to encode some lossy thing into lossless and hope for quality increases. It's about before you, rather than you.

I mean the source that the original encoder used, was that some good enough source to warrant lossless? Actually, considering it's some music track, most likely it is. Probably encoded directly from CD or something. So don't mind me, the post was kinda stupid.
Yeah, the source is lossless:
1) I got it as a CD image with an accompanying CUEsheet (not individual tracks)
2) It checks out against CDDB, meaning the hashes match




Anyway, here's the results (quite surprising):
Spoiler:
A: MP3, 128kbps, Joint-stereo [LAME with -v0 switch]
B: WMA9 Std 96kbps [Windows Media Encoder, with 2-pass encoding]
C: LC-AAC 96kbps [NeroAAC]
D: <Original>
E: HE-AAC q0.25 (average bitrate=69kbps) [NeroAAC]

B was meant to be the obvious bad one - surprising most of you couldn't tell - if you're having trouble, focus on the sounds the symbols in the background make - WMA appears to be very bad at reproducing "sharp" sounds, especially those in the background.
