vcdef "Stereo Mics" stereo mic_in 16 17
As an example of creating a monaural microphone connected to input 8:
vcdef "Podium mic" mono cr_mic_in 8
And the system will respond with
vcdef "Podium mic" mono cr_mic_in 8
vclist Action
The vclist action returns the complete list of virtual channels that have been defined with the vcdef action.
The vclist action accepts no arguments and has the following syntax:
vclist
vclist Acknowledgments
When the vclist command is executed, SoundStructure will send the acknowledgment prefaced with vcitem
in the following syntax:
vcitem <label> <vctype> <pctype> <num> [<num> ...] <term>
A vcitem acknowledgment will be received for each virtual channel that has been defined. The
acknowledgment will be sent to the interface that initiated the request.
Each of the acknowledgment arguments is defined below.
<label>
The <label> argument is a user-defined text argument that specifies the name of the virtual channel that
was defined.
<vctype>
The <vctype> argument is a system-defined text argument that defines the type of virtual channel that are
created. The list of vctypes is included in the vcdef Action section.
<pctype>
The <pctype> argument defines the physical channel type of the physical channels in the virtual channel.
The <pctype> argument is a system defined text argument that must be one of the pctypes listed in the vcdef
Action section.
<num>
One or more <num> arguments are returned with the indices of the physical channel(s) defined as part of
the virtual channel.
vcundef Action
The vcundef action is a virtual channel definition command that undefines a virtual channel that was
previously defined with the vcdef action. Commands with the vcundef action have the following syntax.
vcundef <label> <term>
Each of the command arguments is defined below.
