INTRODUCTION
MUSICAM USA the World’s Leader in codecs gives you the new LIBERTY “POTS only” codec intended
for bi-directional, remote and unattended operation.
With the introduction of the Voyager POTS Codec, MUSICAM USA has demonstrated that stable high
bandwidth links with unfailing audio and data is the new reality for broadcasting over an analog telephone
line. The new Liberty codec incorporates the same superb DSP algorithm delivering crystal clear 15kHz
mono audio in real time at bit rates as low as 24kbps with very short 100ms coding delay and a minimal loss
of quality over a standard telephone line.
LIBERTY is the economical model of MUSICAM USA’s POTS Line. It offers the same excellent audio
quality of the Voyager at a much lower price.
Liberty provides audio-link opportunities previously impossible or simply too expensive. Broadcast
journalists and sports casters now have an easy to use, high quality, compact portable field codec. LIBERTY
can be transported as carry-on baggage allowing convenient worldwide coverage with minimal equipment.
Using the LIBERTY is as simple as plugging it into a POTS phone line and dialing the destination number.
The receiving Liberty automatically answers the call and establishes the link. For POTS connections, a built-
in modem negotiates the best possible data rate for high quality low-noise and distortion free, bi-directional
audio.
LIBERTY features include:
•
High quality audio at very low bit rates (as low as 9600bps)
•
Remote control features for remote operation
•
Special modem for POTS codec operation
