The Audio Mixer Module
The Audio Mixer module can best be described as a modular digital audio workstation. Several channel strips can be combined to create an audio mixer with the desired number of inputs and outputs. A channel strip typically consists of a fader to control the channel's volume, an audio peak meter to monitor the channel's audio levels in dBFS and an input gain and pan setting. The module makes dealing with various audio sources transparent as different sources, internal and external, can be used interchangeably. Audio from each source is converted to a high quality (floating point) internal audio format. Rate matching is applied to keep latency low and constant, both per source and overall.
Right click a channel strip to open its popup menu. The following additional menu entries are available.
<input> Audio Follows
Select a module here to automatically change the audio level with the module's tally status: if the module's tally is selected (white) or program (red) the fader will go up to its previous position, if it's selected for preview or not at all the fader will go down to mute the channel. Default this is off (None).
By default an input is always processed as a stereo signal. This option allows you to use only the left or right channel, which is then mapped to both channels.
Set all controls on the channel strip to their default values.
Enables you to change the channel strip's bottom caption.
Removes the channel strip.
This option is available when right clicking the Monitor channel strip. Select the external audio device that will be used to monitor audio, typically this will have monitor speakers or headphones connected.
Add Channel Strip
Adds a new channel strip for the selected input. Audio can come from internal Modules and external Audio Devices.
Appearance > Gain
Gain can be set from -99..0 dBFS. This setting can be used to attenuate audio from modules, to control the Windows level setting for external devices or even control a hardware preamp for external devices (determined by its driver). Default setting is 0 dBFS.
Appearance > Pan
Allows panning of the signal, i.e. change the distribution between left & right channels.
