17. Neue Soundkarte für den A1200-Uhrenport angekündigt

»ANNOUNCE: DELFINA 1200 - NEW DSP AUDIO CARD FOR AMIGA 1200

1. TECH

Delfina 1200 is based on Delfina Lite, the most successful DSP card on Zorro-II Amigas. The main difference between these two is that Delfina 1200 connects to the internal clock port of A1200. This way the PCMCIA and expansion slots can be used for other devices. The modern manufacturing allows a very low price: SRP is $299.

Delfina 1200 is primarily a DSP audio card, and it is best suited for producing and recording audio with optional realtime effects. Effects can be applied on any sound produced by Delfina or external source transparently, and all the sounds produced by Delfina-capable programs or external source can be mixed into Delfina's output. Delfina 1200 is also freely programmable for all general computing tasks using the supplied compiler and libraries.

• 37 MHz Motorola DSP56002 digital signal processor

  » 18.5 MIPS, upto 110 MOPS » 24 bit data bus (144 dB dynamic range)

• 96kB (32kWords) SRAM

  » Zero-waitstate (12ns)

• Stereo audio codec (Crystal CS4231A)

  » Sample frequencies upto 48 kHz at 16 bit » Three stereo inputs, one stereo output » All inputs can be mixed with Delfina's output » Full duplex recording and playback » One stereo RCA input » One stereo 3.5mm input with optional 20dB mic amplifier » One stereo RCA output » Internal connector for audio input from CD-ROM » Fully programmable using the supplied software » Registered version of SoundFX 3.50 software included

• Amiga 1200 with an empty clock port
• AmigaOS 2.04 or higher
• about 5MB of hard disk space

2. SUPPORT

Delfina 1200 fully supports AHI, the retargetable audio standard for Amiga. Number of AHI supporting programs is steadily increasing. Delfina also has emulation for the Toccata card.

In addition to AHI standard, Delfina 1200 can run multiple Delfina and AHI programs at the same time, and various effects can be applied to any program's output. If multiple programs are producing sound, Delfina will mix the outputs.

Only Delfina's DSP usage and internal memory set the limits.

Software supporting Delfina includes:

• Octamed SoundStudio
• AudioLab16 for Delfina
• SoundFX
• Digi Booster Pro
• Hippoplayer
• APlayer
• SinED
• Play 16
• ShapeShifter
• Fusion
• and many more.

Delfina 1200 system software includes:

• AHI (Audio Hardware Interface) driver

  »	PlayŽ multiple channel audio
  »	AHI standard allows you to write software that works on other audio
  	boards or normal Amiga audio too

• delfina.library

  » For basic operations and user's own DSP software » Supports DSP program multitasking » Enables audio playback and recording

• DelfPrefs

  » * Utility to adjust Delfina's parameters

• DelFX

  » Multiple realtime effects » Record and play AIFFstereo samples at 4000-96000 Hz » Configurable shortcut effect combinations » Can be used to process input or output of other programs

• DelfLoad

  » Shows DSP usage and other statistics

• MUI 3.8 unregistered version

  » licensed for use with Delfina software

• A56

  » DSP56002 assembler » Allows you to write your own DSP programs

• Many example programs including source code
• Software upgrades available for free, at http://www.sci.fi/~petsoff/ftp
