Audio

This section describes available audio configuration parameters. Included are permitted values and, if applicable, guidance for configuring related parameters.

Audio Parameters

Use the following parameters to configure audio settings on your system.

voice.acousticFence.enable

Specifies if you want to enable Polycom Acoustic Fence technology.

This setting is disabled if you set voice.stereo.enable="True".

False (default)

True

voice.acousticFence.radius

Specifies the width of the Polycom Acoustic Fence beam.

0-10 (default is 5) - Higher values increase the width of the audio fence beam between the primary and fence microphone(s). Use 0 for the narrowest beam (20 degrees) or 10 for the widest beam (120 degrees).

  • For Studio X50 and Studio X30 systems: Higher values increase the width of the audio fence beam. Use 0 for the narrowest beam (24 degrees) or 10 for the widest beam (120 degrees).
  • For G7500 systems: Higher values increase the width of the audio fence beam between the primary and fence microphone(s). Use 0 for the narrowest beam (20 degrees) or 10 for the widest beam (120 degrees).
voice.alertTone

Specifies the audible tone for user alerts.

You can’t provision this parameter if the system is in Partner Mode.

Tone_1 (default)

voice.in.hdmi.level

Sets levels for the left and right channels of the HDMI audio input.

You can’t provision this parameter if the system is in Partner Mode.

0-10 (default is 5)

voice.in.3p5.level

(G7500 only) Sets levels for the left and right channels of the 3.5 mm stereo audio input.

You can’t provision this parameter if the system is in Partner Mode.

0-10 (default is 5)

voice.in.3p5.playbackOption

(G7500 only) Specifies how audio from the 3.5 mm stereo audio input is routed and controlled.

You can’t provision this parameter if the system is in Partner Mode.

Playback to All Locations (default) - Set this value if you’re sending audio from a device.

  • Near and far sites hear the 3.5 mm stereo input.
  • You can’t mute audio or control echo cancellation.

Playback to Far Sites - Set this value if you’re using an external digital signal processor (DSP), such as Polycom SoundStructure, which provides mute controls and echo cancellation.

  • Only far sites hear the 3.5 mm stereo input (there is no associated video content).
  • You can’t mute audio or control echo cancellation through the system.

Playback to Far Sites, Mute Controlled - Set this value if you want to perform activities like sharing music from a mobile phone to call participants.

  • Only far sites hear the 3.5 mm stereo input (there is no associated video content).
  • You can mute audio but can’t control echo cancellation.

Playback to Far Sites, Mute Controlled, Echo Cancelled - Set this value if you’re using a line-level microphone. (Note: The microphone must provide the line-level signal to work.)

  • Only far sites hear the 3.5 mm stereo input (there is no associated video content).
  • You can mute audio and control echo cancellation.
  • Mic-level inputs aren’t supported.
voice.liveMusicMode.enable

Specifies whether the system uses M-Mode, which transmits audio using a configuration that best reproduces interactive and live performance music picked up by microphones. This feature provides the highest-possible bandwidth for audio.

You can’t provision this parameter if the system is in Partner Mode.

When M-Mode is enabled, even the faintest musical notes come through clearly.

False (default)

True

Note: Noise reduction features are disabled when M-Mode is enabled.
voice.muteReminder.enable

Specifies if a notification displays indicating microphones are muted when speaking is detected.

You can’t provision this parameter if the system is in Partner Mode.

True (default)

False

voice.noiseSuppression.enable

Enables Poly NoiseBlockAI, which during calls eliminates background and extraneous sounds in common working environments when no one is talking.

When you enable M-Mode (voice.liveMusicMode.enable="True"), this feature is disabled. If an external echo canceller is used, keyboard noise reduction is not available.

You can’t provision this parameter if the system is in Partner Mode.

False

True (default)

voice.out.line.mode

Specifies how the volume for a device connected to the line out port is configured:

You can’t provision this parameter if the system is in Partner Mode.

variable (default) - Allows users to change the volume.
