Video Slave 4 - The Audio Settings Window

Video Slave has some very sophisticated audio features that will help you in your every-day workflow. When dropping a movie onto the timeline, Video Slave will automatically create audio tracks and regions for all audio tracks the movie contains. But it doesn't just play them back, you can also route every single track to your desired output destination. This article will discuss Video Slave's audio settings window which contains several related settings and is also the place for managing audio output busses.

VS4 Audio Settings Window 1

Here you see the audio settings window. It can be displayed by going to the Window menu and selecting "Audio Settings" or by using the Shortcut Shift+A. The window is separated into two sections: the settings section at the top and the actual routing section at the bottom.

Settings Section

  • Output device
    Video Slave will scan your system for all available audio devices when it starts. These devices will be listed here and you can pick the one you want to use for audio output here. Video Slave will store and restore all output busses and their routing using the matrix below on a per-device basis.
  • Sample Rate
    Pick the sample rate you want Video Slave to use. If you're running your DAW on the same machine, please make sure that this is set to the same sample rate your DAW is set to. If the machine is running only Video Slave, typically 48kHz is the best setting to use.
  • Beep Out
    By default, Video Slave plays audio beeps during streamer events. You can pick the output Video Slave uses for these beeps here.
  • Beep Level
    Select the output level of the audio beeps here.
  • Beep Pitch
    Video Slave's audio beeps are simple sine waves. You can select your preferred pitch here.
  • Center remaining channel if one stereo channel is muted
    Video Slave allows for individual muting of the left and right audio channels of stereo tracks. If one channel is muted by right-clicking the mute button, Video Slave will center the remaining channel if this checkbox is ticked.

Routing Section

At the bottom of the window, Video Slave displays a routing matrix which allows you to define output busses and route their individual output channels to physical output channels of your audio interface. To create a new channel, click the "Add Bus" button at the bottom. Use the popup menu next to the button to select which kind of bus you want to create. You can choose from Mono up to 7.1. If stereo output pairs are good enough, you can have Video Slave create those for you by clicking the "Create Default Stereo Busses" button on the bottom right. When a new bus is created, you can edit its name by double-clicking the row header in the list. If you want to delete an output bus, select the row by clicking the row header on the left and hit backspace. Routing of the individual channels to physical outputs of the device is done by simply dragging the channel icon around.

Every output bus you create in the routing matrix will be selectable as an output destination for audio tracks in the track view of the main window. If the audio track's channel count doesn't match the output bus' channel count, Video Slave will up- or downmix the audio content automatically.
