Asynchronous audio playback

This function requires the Pro License or higher. See Licenses and functions.

Asynchronous loop playback allows audio to be continued even if the Locator stops at a pause marker. This way some music or other sounds can be continued in Speaker Support Mode while the presenter is speaking. Asynchronous sound can also run in a loop, i.e. it starts from the beginning again and again. This very convenient if you do not know exactly how long the break will be.

Asynchronous audio playback requires a sound card with "multi-client" capability and WDM drivers (...ASIO drivers cannot be used). While the normal, up-to-date stereo sound cards usually have "multi-client capability", whereas professional sound cards and interfaces usually don't.. If you want to use a professional multi-channel sound card, you need to use a separate stereo output for asynchronous playback. This allows synced soundtrack and asynchronous interval sound to be mixed externally.

And this is how it is done:

For asynchronous playback you need an audio track to be output asynchronously. Right-click the track head of an empty audio track and select Properties. Add a new audio track if no empty track is available. See Adding tracks.
Add a checkmark next to Asynchronous mode for presentation and close the dialog by clicking OK. The symbol in track head will change as an indication for asynchronous mode.
Drag an audio file from the Medial Pool into the asynchronous mode track. Please note that a track in asynchronous mode does not allow any crossfades by shifting the objects on top of each other.
You can now start playback for the audio to be played back as usual. When you press the space bar and put Wings Vioso RX into Pause Mode, the audio on the asynchronous mode track continues playing. You can now start and pause playback as desired; the audio in the asynchronous mode track is continued until the end of the audio file.
Paused playback can also be achieved by setting pause markers. When the Locator stops at a pause marker, playback of all tracks is paused except for the sound on the asynchronous track.

It is possible to Enable loop mode for audio objects to ensure that asynchronous interval music continues to be played even during longer breaks. For this purpose, right-click the object, select Properties and place a checkmark next to Loop. Please note that always the entire media file is looped. If necessary, create a short, loopable file by cutting and exporting. See Creating a loop file. An object with Loop properties can be extended arbitrarily independently of the media file.
The ramp band for the volume is also considered in asynchronous mode. If playback of an object is started on an asynchronous mode track, the volume is controlled in accordance with the visible ramp band. When the Locator stops (Pause Mode), the ramp band further along the object is considered. I.e. the audio object is run entirely asynchronously, independent of the current Locator position.
If Loop mode is enabled, the volume is controlled in sync with the ramp band, while the sound is run asynchronously in a loop. This is a very practical method for Speaker Support as it allows the volume to be adjusted to the corresponding situation via the ramp band. This allows a smooth transition between synchronized soundtrack and interval music.
Please bear in mind that audio objects on asynchronous tracks cannot be considered for level display. Also master level verification via "Peak Search" is not possible. The level of asynchronous audio objects can only be verified via the Properties Dialog. See Sound Object Properties.
The volume of asynchronous audio cannot be changed using the level display controls. You can only do so via the Object Properties Dialog or by changing the ramp band.
Currently, ASIO drivers cannot be used for asynchronous audio playback. The sound card must have multi-client capability and use a WDM driver. See also Options - Global Options - Sound cards WDM.
