   All of which is, in fact, simply the linear sum of a collection   
   of sinusoidal waveforms. If you dispute this, take it up not   
   on this forum, but go argue it with the likes of Fourier,   
   Nyquist and Shannon. And good luck with that, let us know how   
   it works out for you.   
      
   "Attack" and all the rest are completely withing the capabilities   
   of ANY limited-bandwidth system, be it continuous of discrete   
   time-sampled. The ONLY limitation is the actual bandwidth and   
   dynamic range of the system.

   Your primary mistake is that you make such an assumption,   
   which is contrary to fact. I, along with many, many others,   
   have actually carefully and throughly analyzed the actual   
   content of analog rcordings, the properties of the microphones   
   used to make them, and all the equipment in the reproduction   
   chain, and 20 kHz is a VERY optimistic upper limit to the   
   ACTUAL content of vast majority of distributed analog medium.

   In analog recordings, that's true, it's often much lower.   
   What may exist above that on the final distributable product   
   is almost always comprised of non-signal-correlated noise   
   not present at the time of recording.

   There's nothing wierd at all about either of these formats.   
   Both are fully supported by even the lowliest of storage   
   formats, WAV files.
