so the board name will be "MP3/MP3Pro/MP3+V"
There's a new technology out there. It's called Plus-V (or MP3+V). It follows a similar approach than MP3 Pro. It creates an MP3-compatible baselayer bitstream and adds another layer of proprietary high frequency coding. Of course this is NOT high quality. What they do is a parametric approach to encode noise power in high frequency subbands and separately encoding additional harmonics. I'd love to hear how it will sound. Check out their website. http://www.plusv.org/intro.php Unfortunately, they got patents on this. [ This is a double-posting and also appeared on r3mix.net ;-) ] |

>SBR. Any chances of seeing an implementation for >AAC at a later time? If someone makes an AAC implementation, then why not? The only thing that must be made certain of is how to embed PlusV data to an AAC bitstrem. MP3 has a very convenient pointer that allows for the encoder to force the MP3 decoder to skip some data (See for the technical spec at http://www.plusv.org/ for details). This force-skipped data can then contain PlusV data. Everything is 100% compatible with vanilla MP3, old MP3-only decoder's don't see anything wrong with the bitstream, and generally everyone is happy. Unfortunately I don't know AAC at all on the bit-level, so I cannot say if it has as convenient hooks where additional data could be put in a compatible way. Kind regards, - Leopold |
