INTRODUCTION ORBAN MODEL 1100
Any audio editing application that is Microsoft Windows WDM-compliant will work
with OPTIMOD-PC. For example, Adobe Audition supports batch processing, so you
could use it to process many audio files while unattended.
Most streaming encoders have a mode to record/encode in their native file formats
in real time. If you do not need the interim .WAVE file, encoding directly will elimi-
nate a step and will save disk space and time.
Loudness
You can expect a significant increase in loudness from OPTIMOD-PC processing by
comparison to most unprocessed audio.
An exception is recently mastered CDs, which may have already been ag-
gressively processed for loudness when they were mastered.
In radio broadcasting, it is generally believed that loudness relative to other stations
attracts an audience that perceives the station as being more powerful than its
competition. We expect that the same subliminal psychology will also hold true in
netcasting.
Choosing your Encoder
The state of the art in encoder technology is changing rapidly. At this writing, the
best audio encoder technology available is Coding Technologies AAC/aacPlus v2
(MPEG-4 Enhanced HE-AAC). Orban is the first provider of this technology for
streaming audio applications with OPTICODEC-PC. OPTICODEC-PC can provide enter-
tainment-quality stereo streams at 32 kbps. At 48 kbps, many listeners prefer the
sound to that of FM.
OPTICODEC-PC PE is designed to work exclusively with OPTIMOD-PC to form an
overall audio processing / coding chain with the highest audio quality possible for a
given bitrate. These two components are also available from Orban as part of a
turnkey system called OPTICODEC-PC Encoder, which includes a rack mount Win-
dows XP computer with both components pre-installed and pre-configured.

OPTICODEC-PC FE is highly capable MPEG-2/4 AAC/aacPlus™ software for high qual-
ity audio file encoding. OPTICODEC-PC FE offers the most important feature that the
basic netcaster is looking for in a file-encoding product — entertainment-quality
sound at economical file sizes.
Files encoded with OPTICODEC-PC can be experienced through RealPlayer® 10 (or
higher), QuickTime 6.5 (or higher), or Winamp 5.05 (or higher) as well as Apple
iTunes and iPods® and all other AAC/aacPlus-enabled 3GPP cellular devices.
OPTICODEC-PC FE is ideal for podcasters and can even encode ringtones, which are
now an important new source of revenue for production houses.
Be aware that different encoders are optimized for different bitrates, and you
should match your encoder to your potential audience. An encoder appropriate for
a dial-up rate of 20kb/sec may not be optimum for ISDN, DSL, or E-1/T-1 rates. This
makes it necessary to use more than one algorithm to optimally serve audiences
with these disparate connection speeds.
