WarpAmp version history (c) SDG 1997
------------------------------------
Version Changes
------- ----------------------------------------------------------------------
ß2a * Memory leaks fixed.
* New volume bar.
ß2 * A PM gui with drag'n drop and playlist support. Priority can
be adjusted on the fly.
* Only one command line switch left in, "-downmix", which bring
cpu load down by only producing mono sound output. You can
still specify a filename at the command line though.
ß1d * Fixed the "Missing parameter for option ..." text that popped
up when using -priority.
* Fixed the SYS3175 when the mixer device couldn't be opened
(for example when you start a second copy of WarpAMP).
* The valid range of buffers for the -b option changed to
[4..92].
ß1c * It has been optimized for the Intel Pentium CPU (which also
works great with the AMD K6) and it should use significantly
less CPU on systems based on those CPU's (about 20% less CPU
load can be expected). Portions of the code is now inlined,
hand written, assembler, Those of you using Cyrix CPU seems
to be out of luck in this version, the people that have
tested this version on a Cyrix CPU has reported no
significant changes in CPU load.
* There is a new -priority option that lets you specify which
priority the player should execute at.
The range is [1..4], where: 1 = idle time
2 = normal
3 = foreground server
4 = timing critical
WarpAMP uses "-priority 3" by default.
* There is no longer an "AMP_NPB.EXE" version, use the
-priority option instead.
ß1a * There's a -b option that lets you specify the number of 60 kB
buffers WarpAMP uses. You can specify anything between 8 and
500 buffers.
* Changed some of the compiling options, ß1a should be slightly
faster than ß1 (at least it is on our systems).
* There's also an executable called AMP_NPB.EXE which is
basically the same as AMP.EXE, but it doesn't have the
priority boost feature that AMP.EXE has. Those of you who
have had problems with AMP hogging the system could try
AMP_NPB.EXE.
ß1 * Initial release
