	  AHI v4 for making noise


NOTE TO THE MAINTAINERS OF AMINET:

  The last ports of amp until version 0.7.2 have been made by Michael Cheng.
  He gave me a written permission to replace his ports and to continue his work.
  Thanks Michael!


This is the Amiga port of amp-0.7.3, which is finally able to play MPEG audio
Layer III in realtime on a 68060/50! However, mpega (also to find in mus/play)
is still faster - but I want to continue this port as it will be useful when
PowerPC-boards are available.


Installation:

  Copy the executable for your type of CPU wherever you want, that's it!

  If you have installed X-Windows from ADE (ftp://ftp.ninemoons.com) and want to
have   a GUI, you can use the one in xmpeg3.tgz, but you also need to install
tcl/tk.


Usage:

  You can get all options by simply starting amp without any options.

  I have removed buffered output (-b and -nobuffer options) as it slows down  
performance at the moment without asynchronous writes, but I plan to implement  
it in the next version.

  AHI Modes are set via AHI-Prefs, part of AHI v4.
  The performance you achieve is stronly dependent on which audio mode you
choose. On my   configuration, amp needs about 95% with paula-14bit-stereo++ 		 
     and about 65% with paula-8bit-mono,   although all samples are calculated
in 16 Bit/Stereo! (only with a Stereo-MP3, of course ;))
  note: amp always uses Unit 0, this restriction will change in the future. If
amp 	should stop without any obvious reason, it's because of heavy CPU-load,
then 	AHI might forget sometimes to signal the end of a played buffer - I hope
that 	this will be fixed soon, as I couldn't find any bug in my sources ...


TODO:

  - implement Michael's mono and frequency divide options
  - buffered output
  - optional direct 14 Bit output without using AHI
  - improve documentation
  - faster decoding
  - better configure.in
    and more ...
