CDDA

How do you create CDDA data?

Q)

How do you convert the data into a form that can be actually handled by a computer and then incorporated into a CD-DA?

A)

Assuming a Macintosh, in general

• Use Digidesign's Sound Designer II (SD II) to record HD or convert existing AIFF files to SD II format.

• Transfer SD II files to DOS or Unix.

• By converting to endian using SWAP.EXE etc. attached to VCD, it can be used with VCD etc.

The CD-DA data to be passed to the VCD etc. should be anything as long as the PCM data of 44.1KHz 16bit Stereo is arranged as shown below.

• One frame consists of two words. The word is 16bit, little tondian.

• The first word is the left channel and the second word is the right channel.

+0 +1 +2 +3 +4 +5 +6 +7 byte
 -------- -------- -------- -------- -------- -------- - ------ --------
| <---------- frame 0 --------------> | <---------- frame 1 ------- --------
| <------ left -----> | <---- right ------> | <------ left -----> | <---- right -------
| <-low-> | <-high-> | <-low-> | <-high-> | <-low-> | <-high-> | <-low-> | <-high -

Then in the script to build the CD, each CD-DA file

 Track CDDA
    Pause 150
    FileSource \ sample.da
    EndFileSource
 EndTrack 

I will write something like that.
Never change the "Pause 150" part in the above description.
This is required for one CD-DA data.
Also, be sure to set the PostGap of the track immediately before the CD-DA track to 150.
