Multi-channel sound

Projects with multi-channel sound require the Pro License or higher. A multi-channel project is created in two steps:

• Assigning sound card outputs

• Assigning output channels to the audio tracks

Output of multi-channel sound can be effected via a computer with the corresponding multi-channel sound cards (up to 32 channels) or as a WMV format video with 5.1 or 7.1 channel mode. See also Producing a Windows Media video.

Assigning sound card outputs

First of all, you need to assign the outputs of your sound cards to Wings Vioso RX.

1. Click Options in the tool bar below the main menu or Extras and Options in the main menu and select Sound cards ASIO or Sound card WDM in the left field of the Options dialog. If this entry is not visible, click on the plus sign next to Global Options.

Note: In most cases the choice of ASIO sound cards will be appropriate, as ASIO drivers allows multi-channel sound even with standard sound cards or onboard sound chips, provided they have several outputs. You only need to install software tool ASIO4ALL which is available on the web at www.asio4all.de.

Assigning output channels to the audio tracks

Every audio track in Wings Vioso RX usually has a stereo output for signal output assigned to it.  However, it is also possible to assign the signals on one audio track simultaneously to several outputs.

Assigning the audio track to a stereo output:

1. Right-click the track head and select Properties.

2. Under Audio output select the required stereo output for the track.

3. For field Name you can enter a designation to be visible in the track head, e.g. front, rear, center...

• Channel assignment for WMV videos with multi-channel sound in 5.1 or 7.1 mode must be in accordance with a certain pattern. See also Producing a Windows Media video.

• You can also choose a color background for the audio level display, ... See Global options – Audio Level.

Assigning an audio track to several stereo outputs:

1. Right-click the track head and select Properties.

2. Place a checkmark next to Enable multi-channel assignment, followed by clicking on  Multi-channel settings.

3. In the following dialog you can select up to 24 output channels, by preselecting the range of visible channels on the left. To enable a channel, you place a checkmark at its top and click field –inf (...or the db value) to set the slider to zero dB. Of course it is also possible to enter any other output level.

Please bear in mind that an audio track outputs two different signals for stereo files: Stereo left can only output to channels with odd number, while Stereo right can only be output to channels with even numbers.

4. Close the dialog by clicking OK. For field Name you can enter a designation to be visible in the track head, e.g. front, rear, center ...

5. Close the dialog by clicking OK. As a sign for multi-channel output the track head will show three loudspeaker symbols.

• You can directly call up dialog Multi-channel settings by holding the Ctrl key while clicking (audio effects in the track head). In addition to this, the slider controls can also be adjusted during playback.

• If you want to play back a multi-channel soundtrack as mixdown on a stereo output you can allocate this output several times. However, there are a few sound cards, that do not support this feature and will cause problems. See Options – Global Options – Sound cards.

• The audio of a video with multi-channel sound is extracted in the form of several stereo wave files. The first audio file, which as a rule contains the left and the right channel for the front loudspeakers, is placed in the timeline. The other files are placed in the same location as the video file and need to be added manually to the sound tracks in accordance with the multi-channel setup.
