Oh god, let define a few thing. Generally Transparent = MP3 LAME @ ~ 128kbps. That is the good old standard. There has been PR and marketing materials, much like Video Codec making claiming they are 50% better then H.264 or AVC or whatever. AAC or MP3Pro even claim to be MP3 128kbps quality at 64Kbps. Of course which never happened even after years of fine tuning. Opus is the first and only codec in years, or decades…

>Generally Transparent = MP3 LAME @ ~ 128kbps. That is the good old standard. Says who? And which version of LAME? That encoder has seen huge improvements over the years. We should not define audio transparency by an outdated and flawed format. We should define audio transparency by whether it is distinguishable from a lossless source or not. But yes, a modern version of lame (3.98 or newer) will be transparent aroun…

I never said AAC is worst, but AAC 96Kbps cant beat MP3 128Kbps in majority of cases.

You can't just dismiss it and hope that it is. The MPEG LA has been successful with their other patent pools. They've got a good chance of being successful with this one as well. That's what happened to VC-1. Microsoft tried to release VC-1 on royalty-free terms but the MPEG LA formed a patent pool and then it was no longer royalty-free.

MPEG LA has been succesful similarly to why Netflix and the iTunes Store were succesful: make it easy and affordable to comply. On the other hand suing costumers who torrent movies was not succesful at all.

It's far from affordable, that's why HEVC failed miserably. Not everyone has deep pockets to pay for protection racket.

Yes it can. It absolutely can, and does.

I know it's one listening test out of many, but they all agree. AAC (with a good encoder, such as Apple's) at ~96kbps is better than MP3 at ~130kbps.
