- DAT Manager, invoked from the command line as _d_a_t_m_a_n, allows
- you to play audio DAT tapes on the IRIS SCSI DAT drive. The
- audio is played through the IRIS audio hardware.
-
- DAT Manager is a recorder as well as a player. It can
- record data coming from the IRIS audio hardware or from a
- file in the computer's file system. The tapes recorded and
- played by DAT Manager are compatible with commercial DAT
- recorders. DAT Manager also allows you to copy digital
- audio data directly from a tape across the SCSI bus to a
- disk file.
-
- DAT Manager and CD Manager are actually the same program.
- The name used to invoke the program, or a command-line
- option, determines whether the program runs as CD Manager or
- as DAT Manager.
-
- IRIS Digital Media Development Environment 5.3 (included
- with the standard IRIS Development Option 5.3) includes
- source code for a command-line tool, _d_o_d_a_t, which allows
- you to copy tracks between an audio DAT and sound files on
- disk.
-
- The version of DAT Manager included in IRIS Digital Media
- Tools 5.5 is the same as the version that was shipped with
- the 5.3 release.

- This section lists problems in the DAT Manager software and
- ways to work around them.
-
- +o DAT Manager does not let you cue to an index on a tape.
-
- +o The only nonaudio data DAT Manager currently records is
- program number and absolute time code. This means that
- DAT Manager does not record program time. There is
- currently no way to renumber the programs on a tape or
- to erase a program number.
-
- +o DAT Manager displays uncorrected frame numbers when
- playing back a tape recorded with SMPTE time code in
- place of running time.

- +o When recording to a file from DAT Manager, the sampling
- rate stored in the AIFF-C file header is the rate of
- the most recently played portion of the DAT. This
- means that given a DAT that has programs recorded at
- different sampling rates, DAT Manager might create a
- file with the wrong sampling rate if you have just
- played a program with a different sampling rate from
- the program about to be recorded.
-
- Workaround: When recording to disk from a DAT that
- contains programs with different sampling rates, use
- separate AIFF-C files for the different programs. When
- you are about to record a DAT program to disk that has
- a different sampling rate from the last program you
- played, first play a portion of the new program. Then,
- rewind to the beginning of the program and begin
- recording to an AIFF-C file.
-
- +o The music catalog function used by CD Manager is not
- currently implemented for tapes because so few of them
- have the table of contents necessary to uniquely
- identify a tape.
