DAO.EXE

      This is the main disc-at-once recording program. It is capable

  of making AUDIO, CDROM (Mode1), CDROM-XA (Mode2), CD-I, CD+G, and

  MIXED-MODE discs. The resulting discs will be either "redbook" or

  "yellowbook" compatible and can be used as masters for commercial

  CDROM production. You are required to write a CUE SHEET file for

  each disc which defines (among other things) the data files to be

  written and the starting time of each track/index point. This infor-

  mation is used to build the table-of-contents and subcode-Q data on

  the recorded disc (the programs MAKECUE and QUICKCUE can generate

  cue sheets for existing audio CDs automatically). DAO gives you

  complete control over the track/index layout when creating audio

  discs. It is possible to define variable length "pause areas" between

  tracks (down to zero!) and define subindexes to other points within

  a track. Refer to DAO.TXT for more information.



SNAPSHOT.EXE

     This program will make backup copies of just about any CDROM disc.

  Refer to SNAPSHOT.TXT for instructions.



CDCLIP.EXE

      This program extracts "digital audio data" from a CD and stores

  the data in a WAV or other type of binary file. This file can then

  be recorded onto a new CD using DAO.EXE. CDCLIP performs complete

  "jitter compensation" to insure correct digital copies. NOTE: Many

  CD recorders are the best choice for reading audio data, because they

  are capable of reading audio at 2x speed and don't require jitter

  compensation (many CDROM drives can only read audio at 1x speed).

  Refer to CDCLIP.TXT for a list of supported drives.



COPY2CD.EXE

     This program will copy the files from one or more directories

  (on your harddrive) directly to a CD recorder without needing to

  build an ISO9660 image file first. The ISO9660 image is built

  "on-the-fly" as the data is being written to the disc. Refer to

  COPY2CD.TXT for more details.



MAKEISO.EXE

     This program will build an ISO9660 image file from one or more

  data files. Refer to MAKEISO.TXT for more details.



MAKECUE.EXE

      This program will scan an audio CD for subcode-Q data changes

  and generate a CUE SHEET file for use with REDBOOK.EXE. Only a few

  CDROM drives can be instructed to read subcode-Q data (if a drive

  can read digital audio data, it can usually read Q data as well).



ISO2RAW.EXE

      This program will take an ISO9660 image file and convert it to

  raw CDROM data sectors (2352 byte sectors). The resulting file can

  then be used by DAO.EXE to create a data or mixed-mode disc. You must

  convert your image files because some recorders (such as the Philips

  and HP) will only accept raw data sectors when doing disc-at-once

  recording. It takes substantial CPU overhead to convert the sectors

  while recording, so it must be done ahead of time. Refer to DAO.TXT

  for more information on using ISO2RAW.



TOC.EXE

  Displays a disc's table-of-contents on the screen.
