Siren 22 and G.719 Audio Algorithm Support
Polycom’s proprietary Siren 22 and industry standard G.719 audio algorithms are
supported for participants connecting with Polycom endpoints.
The Siren 22 Audio Algorithm provides CD-quality audio for better clarity and less
listener fatigue with audio and visual communication applications. Siren 22 requires
dramatically less computing power and has much lower latency than alternative
wideband audio technologies.
Guidelines
• Siren 22, G.719 and Siren 22Stereo are supported with MPMx cards only.
• Siren 22 and G.719 are supported in both mono and stereo.
• Stereo is supported in H.323 calls only.
• Siren 22 is supported by Polycom HDX endpoints, Version 2.0 and later.
Mono
The Siren 22 and G.719 mono audio algorithms are supported at the following bit rates:
