audiooutput

This object allows individual control of audio outputs on the player.

Object Creation

To create an audiooutput object, use the require() method.

You must also enter an AudioOutputClass (in the example below, "analog" is used). The AudioOutputClass parameter can take the following strings:

“none”
"hdmi” or "hdmi-1", "hdmi-2", "hdmi-3", or "hdmi-4" for Series 5 players with multiple outputs
“usb”
“spdif”
"analog"
“analog:N”
"earc" (AU335 only)
Support for multiple USB outputs using the USB port naming terminology. See roDeviceInfo-getusbtopology

var AudioOutputClass = require("@brightsign/audiooutput");
var audiooutput = new AudioOutputClass("analog");

AudioOutput

Use this interface to create audiooutput objects.

volumeLinear float: Sets the linear volume of the specified output as a percentage represented by a floating point number between 0 and 1 (1.0 is 100%).
volumeDb float: Sets the volume in decibels of the specified output as a percentage represented by a floating point number where 0.0 is 100%
delay long: On Series 3 and 4 players, delays the audio for a specific audio output by lagging decoded samples before they reach that output. Delays are in milliseconds.
treble float: On Series 3 and 4 players, sets the treble of the specified output in decibels. The treble floating point numbers can range from -10 to 10, with 0 indicating no modification to the audio signal.
bass float: On Series 3 and 4 players, sets the bass of the specified output in decibels. The bass floating point numbers can range from -10 to 10, with 0 indicating no modification to the audio signal.
mute boolean: Mutes the specified output if True. This method is set to False by default.
name string: The name of the output.
