2. Project Summary
2.1. Project Description:
Cdrdao records audio or data CD-Rs in Disk-At-Once mode
based on a textual description of the CD contents
3. Business Summary
Cdrdao is used widely in opensource world to create CD in DAO mode,
Ubuntu has cdrdao in its repository,
we need to add it also into our repository.
4. Technical Description:
4.1. Details:
Advantages of Disk-At-Once (DAO) Recording
Recording in disk-at-once mode writes the complete disc,
i.e. lead-in, one or more tracks and lead-out, in a single step.
The commonly used track-at-once (TAO) mode writes each track independently
which requires link blocks between two tracks.
Older CD-recorder models forced a two second pause (pre-gap) between two
tracks
whereas newer models allow adjusting of the pause length in TAO mode
reducing the number of link blocks to a minimal amount.
However, with TAO it is generally not possible to define
the data that is written in pre-gaps.
But exactly this feature makes audio CD recording interesting,
e.g. by creating hidden bonus tracks or track intros in pre-gaps
like it is common habit on commercial CDs.
Finally, DAO recording is the only way to write data to
the unused R-W sub-channels for e.g. CD-G or CD-TEXT.
Features
* Full control over length and contents of pre-gaps
(pause areas between tracks).
* Control over sub-channel data like:
o catalog number
o copy, pre-emphasis, 2-/4-channel flags
o ISRC code
o index marks
* Support for exact audio, data and mixed mode CD copying.
* Support for R-W sub-channel writing.
* Accepts WAVE and raw audio files.
* CD-TEXT reading and writing with drives that support it.
* CDDB access to automatically create CD-TEXT data.
* Support for on-the-fly copying.
