    • Questionable performance even with other  
       PC applications. According to Polycom FAQ 
       on the Communicator: “Skype is the only 
       application that is officially supported by 
       Polycom Communicator model C100S. It is 
       optimized for use with Skype, and if used 
       with other Internet calling or voice 
       applications, Polycom Communicator may 
       experience diminished audio quality and/or 
       loss of button functionality.”
Audio Processing
Built-in DSP - all audio processing 
takes place on the Chat 50 itself, 
utilizing ClearOne’s market-leading algorithms 
for:
• Echo cancellation
• Noise cancellation
• Advanced input & output level management
• 20Hz-20kHz full bandwidth frequency 
   response for deep, rich sound
No on-board DSP processing - 
code is loaded onto hard drive of connected PC:
• Audio processing tasks compete for CPU 
resources with other PC applications such as 
video conferencing over internet
• This could affect echo cancellation and duplex 
performance
• No ability to ever connect to non-PC devices 
because it contains no built-in processing
