ECON Announces the SoundMeister Stereo Amplifier/Digitizer for the Apple IIgs
 
Oviedo, FL - Econ Technologies Inc. announced the SoundMeister, a  full
featured stereo board for your Apple IIGS, began shipping on  April 24.  The
SoundMeister allows you to achieve high fidelity  stereo output by connecting
external, unamplified speakers to your  IIGS.  The SoundMeister's built in 1.5
watt per channel amplifier  and unique filtering produces a smooth, clean
sound that surpasses  any other board ever produced for the IIGS.  The outputs
can even  be connected to an external amplifier in order to achieve even
higher fidelity and volume levels by using SoundMeister's true  line-level
outputs.
 
On the input side, the SoundMeister lets you connect a microphone  or a pre-
amplified source (such as a CD player) so that mono  recordings can be made.
These recordings can be stored as  waveform data that can be incorporated into
System 6 events,  HyperCard IIgs, HyperStudio, and any other application that
supports sounds.
 
A copy of DigitalSession, the ultimate waveform capture/editing  software is
included with each SoundMeister board.   DigitalSession, written by D. Proni
of Econ Technologies, allows  you to record and fine tune digital sounds from
a variety of  sources with a variety of hardware including the SoundMeister.
With DigitalSession you'll be able to compose sounds and use them  within
popular applications such as HyperCard IIGS, HyperStudio,  Sonics, SynthLab,
and the Sounds control panel.
 
Requirements: Unpowered speakers, amplified speakers or standard  hi-fi
equipment can be used as output.  Of course, an Apple IIGS  is required.
 
SoundMeister is currently available and has a suggested retail  price of $89.
