set_volume: Volume functions as a percentage and therefore takes a value between 0-100. The volume value is clipped

prior to use (i.e. SetVoume(101) will set the volume to 100 and return True). The volume is the same for all mapped

outputs and USB/SPDIF/analog.

Note: Separate volume levels are stored for roAudioPlayer and roVideoPlayer.

set_channel_volumes: You can control the volume of individual audio channels. This volume command takes a hex

channel mask, which determines the channels to apply the volume to, and a level, which is a percentage of the full scale.

The volume control works according to audio channel rather than the output. The channel mask is a bit mask with the

following bits for MP3 output:

• &H01 Left

• &H02 Right

• &H03 Both left and right

Example: This code sets audio output to the rightmost expansion moduleaudio port.

video = CreateObject("roVideoPlayer")

video.SetAudioOutput(0)

video.MapStereoOutput(3)

Example: This code sets the volume level for individual channels.

audio = CreateObject("roAudioPlayer")

audio.SetChannelVolumes(&H01, 60) ‘left channel to 60%

audio.SetChannelVolumes(&H02, 75) ‘right channel to 75%
