Circuit Research Labs Inc. (OTCBB: CRLI), parent company
of Orban/CRL, listed No. 192 on Deloitte's Technology Fast 500 in
North America, announced the release of the Orban Opticodec 1020 FE
encoding application for netcasting, file encoding, podcasting, audio
content downloading and mobile 3GPP Devices. A product of Orban's
Personal Computer Product Division, Opticodec 1020 FE is the latest in
Orban's line of "Optimized Audio" products for the Internet.
   The 1020 FE line supports the MP4 family of codecs including AAC
and HE-AAC/aacPlus(R). It can produce iPod(R)-compatible podcasts that
can be streamed live or played on demand, even when the file is still
downloading. Also included are file hinting for streaming applications
and 3GPP mobile phones. The 1020 FE can tag and add graphics for album
art and/or logos. Thanks to the high efficiency aacPlus codec,
downloads of quality comparable to high bit rate MP3s and WMAs can be
done in half the time, using half of the bandwidth, yielding a
superior experience for the user and cost savings for the content
provider.
   The Opticodec 1020 FE Professional and Enterprise editions support
batch encoding that can be launched from the application or command
line. 3GPP Hinting is available on the Enterprise edition only.
   "This is a high-quality, full-featured AAC/HE-AAC/aacPlus encoder
with all the necessary tools and features in one application. It is no
longer necessary to use several potentially incompatible applications
for various file operations," said Greg Ogonowski, Orban/CRL VP of
product development.
