Could AACplus make MPEG-4 the best streaming format for audio?

AACplus is the next evolution of AAC. It’s being used today in XM satellite radio, and it’s on its way to becoming a core audio format for MPEG-4. This is extremely good news for MPEG-4, as a source imtimate with its quality reports:

It is spectaculary better than all proprietary schemes.

AACplus uses Spectral Band Replication (SBR) technology developed by Coding Technologies, and initially deployed for MP3Pro. Although MP3Pro is dead in the water — MP3 is too hampered by its own ubiquity — MPEG-4 was built to be able to absorb new technolgoies like AACPlus. Between AVC and AACplus, 2003 is shaping up to be the year of MPEG-4. | Coding Technologies
