PrismaNG 3.2 -- 26.10.2026
WHAT IT IS
The software for the Prisma Megamix, the Zorro II and clockport sound card
built around VLSI Solution's VS1063a. The chip decodes MP3, Ogg Vorbis, AAC
and FLAC by itself and records MP3, Ogg Vorbis and FLAC, so the Amiga only
moves the data -- music on a 68000, with the CPU to spare.
WHAT IS IN IT
* prisma.library: how every program reaches the card
* mhiprisma.library: the MHI driver, for AmigaAMP and other MHI players
* prisma.audio: the AHI driver, ten modes, four of them full duplex
* PrismaControl: the mixer, a commodity -- volume, balance, a 5-band EQ
or bass and treble, the input monitor and level meters, one hotkey
away (control lalt p); English and German, with a manual in each
* PrismaPlay: the Shell player, with playlists, ARexx, internet radio
and recording
* PrismaRec: the recorder, a cassette deck -- REC, PLAY, PAUSE, the
tape counter, the reels -- that records what the card hears into
MP3, Ogg Vorbis, FLAC or WAV and plays the takes back; Deck '84 drawn
on any screen and two decks of pictures (six more in the package
PrismaRecSkins, mus/edit), an ARexx port with macros that record what
EaglePlayer or HippoPlayer plays, a take a module; English and German
with a manual in each
* PrismaModes: plays a quiet tone in each AHI mode, ticks those your
Amiga manages and puts the ones you confirm into AHI's list
* PrismaEncode and prismadsp.library: a sound file -- WAV, AIFF, FLAC,
MP3, Ogg Vorbis, AAC, WMA and more -- into MP3, Ogg Vorbis or a WAV
format, encoded by the card's chip (a WAV faster than real time even
on a 68000; the compressed ones decoded by the chip too); with a
manual
* Normalise: a recording's loudest peak to a level (16-bit PCM WAV)
* SplitTracks: a recorded record side cut into its tracks at the breaks,
not fooled by crackle or rumble (16-bit PCM WAV)
* SetPrisma, PrismaDiag, PrismaState, MHIState, PrismaBench, AHIBench,
AddPrismaModes and PrismaRecTest: Shell tools
* VLSI Solution's VS1063a patch package 2.6, which the driver loads into
the chip: fixes, and the FLAC encoder
INSTALLATION
Double-click Install. The programs go into a drawer called Prisma, wherever
you choose (SYS:Tools by default); S:User-Startup gets "Assign Prisma:" and
"Path Prisma: ADD", so every Shell finds PrismaPlay by name. PrismaRec goes
there too unless you choose another drawer for it, with its two decks of
pictures if you want them. The libraries
go to LIBS:, the drivers and the patch files to DEVS: -- the AHI driver
only where AHI is installed -- and PrismaControl into SYS:WBStartup when the
installer finds a card. With AHI, the installer then opens PrismaModes: a
minute of measuring, and you choose the AHI modes to keep. Run it again
from the Prisma drawer whenever the machine changes.
