This parameter selects the index of the audio source for the corresponding cr_mic_in or sr_mic_in physical

channels. The index required for this parameter indicates to which physical channel of the virtual channel this

parameter will be applied. For example, indices 1 and 2 correspond to the left and right physical channels of a stereo

virtual channel.

The value of this parameter indicates the index of the audio source type (mic_source_type) that will be routed

to the physical channel.

When mic_source_type is analog, this parameter has no effect.

When mic_source_type is clink_mic, the value of this parameter indicates which ConferenceLink mic element

will be routed to the physical channel.

For example, assume a virtual channel has been defined like this:

vcdef "Stereo Clink Mic" stereo cr_mic_in 1 2

And the source type has been set to clink_mic like this:

set mic_source_type "Stereo Clink Mic" clink_mic

Then we issue these commands:

set mic_source_index "Stereo Clink Mic" 1 5

set mic_source_index "Stereo Clink Mic" 2 6

These commands set the left and right channels of the "Stereo Clink Mic" virtual channel to use the 2nd and

3rd elements of the 2nd ConferenceLink mic.

Queries which microphone index of the microphone array

is associated with the virtual channel 'Ceiling Mic 1 A'.

Since 'Ceiling Mic 1 A' is the first element of the digital

array microphone, the value 1 is returned.

Queries which microphone index of the microphone array

is associated with the virtual channel 'Ceiling Mic 2

B'.Since 'Ceiling Mic 2 B' is the second element of the

second digital array microphone, the value 5 (=3+2) is
