Using Multiple Audio Formats in Your Project
A project can contain audio in a variety of formats; however, there are some restrictions
regarding mixing formats within an element or group of elements, such as menus.
When you are required to have the same audio format within an element or group of
elements, all settings must be the same:
• Audio type: AIFF, WAVE, PCM, AC-3, or MPEG-1 Layer 2
• Number of channels: This is especially true with the AC-3 audio format, because it
commonly supports a variety of channel configurations.
• Sample size: 16 bits or 24 bits
• Sample rate: 48 kHz or 96 kHz
• Bit rate: 64 kbps to 4608 kbps, depending on the audio type
Each audio stream within a track can be in a different format. Within an audio stream,
however, the audio format must be the same for all clips.
All menus within a video title set (VTS) must use the same audio format. DVD Studio Pro
automatically creates additional VTS blocks as needed to support menus with different
audio formats. See
for additional information.
When adding individual audio clips to each slide or when using multiple audio clips for
overall audio, all clips must use the same audio format.
