DVD-Audio Formats
A DVD-Audio project can contain audio in a variety of resolutions.
The sample rates can be 48 kHz, 96 kHz, 192 kHz, 44.1 kHz, 88.2 kHz, or 176 kHz and the bit-depths can be 16 or 24.
You can use other bit depths for audio files in a montage, but they are saved on the DVD-Audio disc as either 16-bit or 24-bit audio samples, regardless of the original precision. The sample rate of the DVD is specified on the Info tab of the corresponding audio montage.
