1.3 File Systems, File Formats, Audio Files
The D424 MO-recorder is based on a SCSI-controlled magneto-optical
drive, and standard ISO disks as storage medium. The same drives and
disks are used in computer applications for storing and archiving.
By using the same file system and formats as MS-DOS based computer
platforms, disks that were recorded with a D424 can be played by all DOS
based systems – from simple multimedia computers to fully professional
audio workstations.
The D424 is storing all audio information to sound files in standard Micro-
soft Wave format (*.WAV), including all relevant recording parameters, as
sampling rate, word length, and number of channels.
All further information on the structure of a session as well as all editing
information are kept in separate sequence files (*.seq), also known under
the name Edit Decision List (EDL).
1.3.1 Takes, Indices, and Sequences
When working with the D424, you don't have to care for sound files, di-
rectories, or disk structures and the like; the following definitions, how-
ever, are important for your recording, editing, and playback work.
The recorded material is subdivided into takes and indices.
• Every time you start recording, a new take is created.
• Place additional take markers during a long recording session. In a concert
you may mark the begin of a new song. This will save time for creating the
definitive markers when editing later.
• Store additional index markers at positions to be edited. Later, you will be
able to address them directly, without the need for searching.
• During the subsequent editing session, all markers having been previously
set can be deleted or moved. New ones can be set in order to prepare your
project for transferring to a CD, with all desired take and index markers.
When you start working with a new project, all settings and editing infor-
mation will be stored to the currently selected sequence. Only one se-
quence can be active at a time, this is called the “Current Sequence”.
• When you start recording on a new disk, a first sequence will be created.
You will stay with this first sequence until you switch to a new one.
• Create a new, empty sequence for a different project. Start recording and
do your editing session in a separate environment. It is very easy to switch
between different sequences.
• You can have several sequences for a single project – do your basic editing
first, copy the current sequence to a new one, and continue with your ses-
sion. You will have access to the basic version at any time.
• Make different versions of an original recording. You can decide at the
end of your projects, which one you would like to keep – or keep all of
them. Sequences do not require much storage capacity.
