IBM Adds Mwave OS/2 Support and Expands Functionality
April 11, 1994
IBM's Microelectronics Division today announced that its popular
Mwave* Technology platform now runs under the OS/2* 2.1 operating
system environment. In addition, it has added significant new
functionality through software upgrades in the areas of communications,
audio, voice and video. Both moves bring the benefits of Mwave to a
broader range of OEM customers and end users.
Already available in the Windows** environment, Mwave is one of the
first open hardware and software subsystems based on digital signal
processing (DSP) technology. The platform can be upgraded in the
field simply through software.
Mwave audio software supports the MMPM/2* (Multimedia Presentation
Manager) interface in OS/2 to provide industry standard functions for
multimedia applications, including audio record, playback, data
compression, audio synthesis and audio mixing. In the Windows
environment, Mwave supports the equivalent Windows MCI (Media Control
Interface). In addition, Mwave's OS/2 support extends to most Mwave
audio capabilities already on the market as well as those being
Added benefits of OS/2 support include customers' ability to use Mwave
software developed for Windows 3.1 in the WIN-OS/2 subsystem that is
part of OS/2 2.1, while application developers can use the Mwave
Developers Kit (MDK) from Intermetrics in an OS/2 2.1 environment.
Host of New Functions
Mwave continues to expand its software portfolio and upgrade existing
applications. The new capabilities cover communications, audio, voice
and video functionality.
Mwave now supports new standards that enable improved performance for
fax and modem transmission, which is especially important for the
increasing number of people using mobile communications.
-- Extension of wave table synthesis - a method that represents
instruments more realistically than generating them mathematically -
to employ 16 voices for better musical synthesis on computers.
Mwave is one of the first DSP systems to be able to improve
synthesizer sound without needing to add hardware. When the wave
table synthesis is combined with Mwave's 5 megabytes of sample
store, music sound quality is comparable to 24- and 32-voice sound
-- Mwave is among the first DSP-based systems to support the Microsoft
Windows Sound System** which ensures that applications written to
Windows Sounds System, such as voice recognition and audio
recorder, will now run on Mwave.
-- Additional Qsound special effects for music enthusiasts to enhance
Mwave's compact disk audio system.
-- "Smart line" feature that differentiates between incoming voice
and incoming fax calls for telephone answering systems hooked up
-- Full-duplex speaker phone which enables people at each end of a
speaker phone to talk and hear at the same time, allowing a more
natural conversation flow than is available through half-duplex
-- VFW (Video for Windows) JPEG (Joint Photographic Experts Group)
code that enables personal computer users to achieve high-quality
video compression at a rate two to three times faster than what is
available under standard Windows.
Because the Mwave architecture is flexible and open, these and
other new features can be quickly and easily integrated onto PC
motherboards or add-in boards.
Mwave on OS/2 2.1 audio functions will be available at the end of
April and there will be no additional charge. All other functions
and features are available today.
