WMA Lossless = Tonally Lossy?

I recently spoke to Duncan about his experience with the WMA lossless format. He is saying that WMA Lossless has an amplified hump in the lower treble, which would make it a pretty terrible to use for archiving. I have noticed this occurring in the lossy WMA formats, but I didn't know this was also the case in WMA Lossless. I was wondering about the experiences of others concerning this format and this problem. Any help would be greatly appreciated, and thanks to you very much in advance.

Sincerely,
Adrian

Er, no. The lossless encoder and decoder cancel each other out. I checked this myself before encoding my files, encoding and decoding a file to make sure it went back to the original exactly. Players will decode during playback, giving the same result as the original. Of course one could write a playback program to add distortion to wma lossless files only; I would assume that no player does this, and certainly not WMP and foobar. (I wonder if this sort of thing is ever done. Probably illegal?)

WMA lossless is perfectly lossless. However, if you're using WMP to play back those files, you're unlikely to get clean playback. You can thank kMixer for that (note that this is not an issue specific to the WMA lossless file format, rather an issue specific to WMP).

Playing back WMA lossless files in Foobar is fine.

Or at least close to one.

BTW, has anyone figured out why M$ often calls WMA lossless "mathematically lossless"? Just curious if they feel this is a greater descriptor for the general public, or a warning towards those expecting complete lossless.

Probably because Bill Gates think analog is the true lossless
