DISC-AT-ONCE CDROM RECORDING UTILITIES 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. 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.
