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.


Unfortunately, they got patents on this.

No, I don't mind at all. Just notice that I have _tons_ of things to do and it may very well be that I don't see all the questions I might be able to help with.

That someone was right, and I am to blame. The download packages were removed immediately when I found out of the problem this morning. Now the packages are there again, but FFTW is replaced with a general, vanilla 512-point FFT. I had a little e-mail conversation with FFTW guys Steven G. Johnson and Matteo Frigo, and I must say that they were real gentlemen when it came to solving the issue. In addition to that, they gave me some invaluable advice regarding patents and licenses.

Thanks to them, I believe that we are going to be able to define our official "legalese" license policy by the end of the next week. Meanwhile: all free software developers will for certain be allowed to use the source codes and the format freely, as long as they don't intentionally break it ( = make it incompatible with itself).

Kind regards,
