DVD-Audio Format Considerations
There are two main considerations when planning a DVD-Audio project: the total size of the album and the highest allowable data rate for a group.
A single album cannot contain more data than 4.7 GB (using a standard single layer DVD).
Highest Allowable Data Rate for a Group
The data rate is the data bandwidth that is necessary to reproduce a given number of channels at a specific bit depth and sample frequency. The DVD-Audio specification allows for a maximum data rate of 9.6 Mbps when using an uncompressed PCM audio format.
To keep a DVD-Audio project within the allowable data rate limit, use the following list as a guide.
- 6 Channels
Maximum bit depth/sample rate: Up to 16 bit/96 kHz or 24 bit/48 kHz
- 4 Channels
Maximum bit depth/sample rate: Up to 24 bit/96 kHz
- 2 Channels
Maximum bit depth/sample rate: Up to 24 bit/192 kHz
