Audio

While shooting in a virtual production environment, audio helps the actor, director, and editor to confirm that the visual scene is in sync with the story. The advanced audio engine lets you add multiple audio tracks in the Story tool, and play them back. In a take-based approach, a take is considered as the destination for an audio file to play. Therefore, you can assign only one audio file to a take.

With the advanced audio engine, you can:

• Stretch multiple audio tracks in time
• Import 16-bit .WAV, .MP3, and .BWF file formats
  NoteYou need to install Apple QuickTime player to import .MP3 files.

  The Broadcast Wave Format (BWF) is based on the Microsoft WAVE audio file format, to which the European Broadcasting Union (EBU) has added a Broadcast Audio Extension chunk. In addition to the audio data, a BWF file contains the metadata which is considered necessary for all broadcast applications. This audio format enables seamless exchange of audio material between different broadcast environments and between equipments based on different computer platforms.

• Export WAV files from MotionBuilder SDK. For more information, see the MotionBuilder SDK Help.
  NoteYou cannot export BWF files.
• Choose left, right, or both channels to play the audio content
• Lock audio speed when constraining the audio to a take

The Audio settings let you load and view audio files and devices, as well as record audio files (in .wav format).

The Audio settings in the Navigator window change depending on what is selected in the Scene browser.

• If the Audio folder is double-clicked, the Global Audio settings appear with a field for setting the playback delay. See Global Audio settings.
• If an audio device is double-clicked in the Scene browser, the Audio Device Settings appear with information and settings that correspond to your computer’s default audio device. See Audio Device settings .
• If an audio file is double-clicked in the Scene browser, the Audio Settings appear with information and settings that correspond to the audio file you just clicked. See Audio settings.

Before you use the Audio settings, ensure that the Layout > Preferences > Loading > Enable Audio checkbox is turned on.
