[Flac-dev] flac improvement??

[Ludovico Ausiello]

hello my name is Ludovico Ausiello, i'm a ph.d at the university of Bologna 
and I've developped an open source alternative to proprietary philips 
superAudioCD encoder (that actually cost some thousands dollars!) that has 
better performance (it's seems strange.. but..) I'm interested to use the 
flac encoder to compress the 1-bit stream that is the output of my encoder 
(I start from 24 or 32 bit wav and then i encode them into a 1-bit stream, 
like in the superaudioCD format). my problem is the sample rate.

eventually the normal commercial format proposed by philips and sony was
signal band = 22.050 HZ => Fs = 44.100 Hz
Over Sampling Ratio = 64 => Total bit rate = 64*44.100 = 2.822.400 Hz
so the superaudio CD uses a 1-bit stream at that sample frequency

I've developped a new algorythm that beat philips'one of at least 3.7 dB in 
Signal to Noise Ratio (the best is a +9.2dB!) and also reduce the power 
consumption of the digital amplifier required to drive the speaker of a 
factor of 5 (you can ask and i'll send you a pdf copy of my paper i 
presented at the Audio Engineering Society convention of the last May..)

I'm very interested in extending the FLAC limitation of sample rate (i've 
read it is 1 MHz!) and i wish to ask you if it's possible to encode also 
these 1-bit streams and then make them playable by an ipod

hoping to receive some help i can only say that the work that you already 
done is amazing, and (if you are interested in testing my algorythm) i'll be 
pleased of sending you my source code files.

thank you very much
