Looks nice, though I would rather see some widely accepted multimedia
container, than just another audio compression cod

Hi,
i planned to write this for quite a while and finally got to it [though it's
not 100% working yet - It's a small program. If experienced unix hackers
might look over y use of waitpit i'd be happy :)]:
lash_wrap
It's a small program which can be used to "smuggle" non LASH apps into a LASH

Yes, there are at least 8 file formats supported by libsndfile that
accept 32 bit float data. Most of these also accept 64 bit double
precision float data, but I personally don't see the point in going
beyond 32 bit float.

It probably would suffer some, but it would still be better than raw. The MSBs
should compress
well, just as if it were reduced to 16-bit; the frequencies should not change.
The LSBs would be
pretty erratic though; like trying to compress noise. But you don't know unless
you test.
Can wav files
Could do that... I wonder if the compression ratio would suffer,
though. Just a hunch.

The JasPer library documentation states that a single image component can be
from 1 to 16 bits per
sample, so not directly. 24-bit color images are actually treated as 3 8-bit
components: like one
red component, one green component, and one blue component.
For lossless compression, we could easi
Pretty cool. Does JPEG 2000 handle float data?
I'd love to be able to write an archive script for Ardour sessions
that compresses the audio data losslessly, but FLAC won't do it.

Hello. I just finished writing and documenting a new lossless and lossy audio
codec called
j2kaudio. It uses the wavelet compression in JPEG 2000 to transcode audio wav
data to and from j2a

Mmmm ... I have a power switch here, so I thought I'd dare to try
