Q: How much is it?
A: It's free!
Q: What are the system requirements?
A: Basically AmigaAMP runs fine on any stock Amiga with at least a 68030-50
MHz processor. However, if you want to be able to play Layer3 without
downsampling and quality loss you need at least a 68060-50. Be prepared to
face heavy system load! :-)
If you've got a PowerPC you can play Layer3 streams in the background without
noticeable system slowdown at all. For the NewGUI (WinAMP lookalike) modes a
graphics card is a must! The GadTools interface works well on the legacy
ECS/AGA display modes though.
Q: Why AHI? It's slowing down my system a lot.
A: That's simply not true! I just performed some tests on a 68040-40.
Have a look at the AmigaAMP Homepage for the results.
Q: Why do I get poor sound quality?
A: AmigaAMP uses the highlevel device access routines of AHI. The big
advantage of this method is that several programs can play at the same time
through only one physical stereo-audio output. AHI does mixing and resampling
on the fly.
The big disadvantage: If you don't configure it very carefully you'll end up
with AHI degrading the sound quality and eating lots of CPU time. (see above)
Q: How can I archieve 44.1 playback without a soundcard?
A: If you have a graphics card (highly recommended anyway), you can have your
audio/video DMA set to double frequency all the time. Picasso96 takes care of
this automatically if you set the environment variable Picasso96/AmigaVideo
to 31kHz. CyberGraphX needs a hack unfortunately, or you can put
C:AddAudioModes DBLSCAN REFRESH QUIET after LoadWB in your startup-sequence.
Have a look at the AHI documentation for further details and requirements!
Q: Why do skins look dithered on my 16/24bit CyberGraphX screen?
A: That's a bug in AmigaAMP 2.0. It will be fixed in v2.1.
Q: I can't get the spectrum analyzer to work. Why?
A: The spectrum analyzer needs AmigaOS 3.1 and PowerUP to run. If one of the
two is missing it will be simply switched off. Only AmigaOS 3.1 provides the
fast, effective and system friendly drawing routines that my spectrum
analyzer routine needs. If you don't have 3.1 by now, rush to the nearest
shop and buy it! :-)
Q: How can I use the WinAMP skins?
A: All the texture sets reside in a subdirectory called skins relatively to
the place where you've installed the AmigaAMP executable. If you're starting
AmigaAMP from the commandline just add the keyword NewGUI. If you're running
it from Workbench, just add the keyword NEWGUI to the icon's tooltypes.
Q: Do I have to convert the skins first?
A: No. Each skin consists of several Windows BMP pictures. If you have a
datatype installed that can handle those, there's no need to convert them. If
you're in doubt you can try loading the pictures into MultiView. If it fails
you'll have to find another datatype or convert the pictures to IFF.
Q: It seems to be playing but I can't hear anything!
A: Probably you've chosen the wrong AHI driver. The driver has to be
configured using the AHI preferences program which should be in your prefs
drawer. Have a look at the manual about how to choose the correct driver.
Due to limitations of some AHI modes you can't always turn the volume slider
higher than 0dB!
