Audio format considerations
There are two main considerations when planning a DVD-Audio project:
The total size of the album.
A single album cannot contain more data than 4.7 GB (using a standard single layer
DVD). In the table below you can see the maximum recording time on a single sided,
single layer DVD for various formats.
The maximum allowable data rate for a group.
The data rate is the data “bandwidth” necessary to reproduce a given number of chan
nels
at a certain bit resolution and sample frequency. The DVD-Audio specification all
ows for a
maximum data rate of 9.6 Mbps (Mega bits per second) when using an uncompressed
PCM audio format. For example, a group containing a 24-bit / 96 kHz 5.1 surround Mon-
tage would exceed this 9.6 Mbps limit, thus it would not be possible to use this group in a
DVD-Audio project.
To keep a DVD-Audio project within the allowable data rate limit, use the
table below as a guide:
If a group’s number of channels and sample rate exceed the 9.6 Mbps data
rate a warning will appear when using the Check function (see “Using the
Check function” on page 568).
Number of
channels
Bit resolution/sample rate Max recording time
6 16-bit / 96 kHz or 24-bit / 48 kHz 64 minutes
2 24-bit / 192 kHz 64 minutes
2 24-bit / 96 kHz 129 minutes
2 16-bit / 44.1 kHz 421 minutes
Number of channels Maximum bit resolution/sample rate
6 Up to 16-bit / 96 kHz or 24-bit / 48 kHz
4 Up to 24-bit / 96 kHz
2 Up to 24-bit / 192 kHz
