It was the lossless claim that got my attention, Jens. I am well aware that
current compressors can beat that at "acceptable" quality. But an ogg at q7
turned into an 192k mp3, or vice-versa, results in a blurred cacophony of
noise because each compressor throws away different stuff. The result is
still like fingernails on a backboard even to these 75 year old ears.

from TFA:
: Implemented in a DSP chip or microprocessor, this simple compressor
: requires about 50 instructions per sample. However, lossless
: compression ratios fall between 1.3:1 and 2:1 on baseband signals.
So a size of 75% expected and on occasion down to 50% after compression.
How is that compared to existing implementations?
