Scope

The Compact Disc Digital Audio (CDDA) job type is for digital audio content stored on a CD in accordance with the IEC 60908 international standard.  See the section on Identifying and Handling Optical Media for more information on how to distinguish a CDDA disc from a data CD.

This operation does not create a conventional disk image of the CDDA file system.  Instead, the BDPL Ingest Tool uses the cdrdao application to create a copy of the raw Pulse Code Modulation (PCM) audio content (saved to a .bin file) and then creates a .cue file with information on the timestamps for individual tracks. The Ingest Tool also uses cdparanoia to create a single uncompressed .WAV file for the entire disc, which can be played in a desktop application or be uploaded to a streaming player for access.

General Operation

Select the 'CDDA' job type and 'CD/DVD' as the media type; once you have inserted the disc into the workstation optical disc drive, check the 'Attached?' box and click the 'Transfer' button.

First, the Ingest Tool will use the cdrdao application to get information about the disc and its track listing, and record this information in a .CUE file (a widely used format for documenting track and timestamp information for audio CDs):

cdrdao will then create a copy of the raw, pulse-code modulated (PCM) audio data on the disc, writing it to a .BIN file:

Following the creation of this preservation copy, the Ingest Tool will use the cdparanoia application to create a single, uncompressed .WAV file of the disc.  The CMD.EXE window will report the status of the .WAV file creation and indicate when you may proceed to content analysis:
