Audio Editing
This chapter covers editing of audio files and Playlists. DigiCart/E can make basic edits to audio files, such
as Head and Tail Trims, Fades (In and Out), Output Gain adjustment, and Pre-roll. Playlist edits provide
lots of flexibility to change Playlists, rather than rebuild them.
Non-destructive audio file edits (Head/Tail Trim, Fade In/Out, Gain) can be performed on all playable
formats. The edit parameters are saved in a vendor-specific area of the file header. When playing WAV
files on non-DigiCart machines, the edits will not be recognized. However, the COPY EDITED utility can
be used to render Head/Tail Trims to WAV files playable on other machines.
The COPY EDITED utility can be used to convert between DigiCart II formats and WAV file formats.
This applies only to linear 16-bit stereo recordings.
User Interface
The Editing menus follow the convention of first selecting the file to be edited, then press the EDIT button.
Next use the selection knob or Navigation Arrow buttons to select the operation that you wish to perform.
Follow the on-screen prompts to complete the operation.
Edit Audio Files
Edit Menu functions of DigiCart/E are non-destructive and can be undone or changed at any time. Edit
information is stored as part of a cut and remains active until changed or removed. The following
parameters can be modified using the Edit menu:
• HEAD
• FADE IN
• PRE-ROLL
• TAIL
• FADE OUT
• OUTPUT GAIN
Most Edit Menu functions are time-based. By adjusting HEAD and TAIL trim, you determine the total
playing time of a cut. Audio gain will ramp up or down according to the time values selected for FADE IN
and FADE OUT. PRE-ROLL is provided so you can preview TAIL trim and FADE OUT edits without
having to play an entire cut. Pre-roll sets the length of time that a cut will play just prior to a TAIL trim or
FADE OUT when auditioning selected values.
Times are displayed in HH:MM:SS:FF.BB (Hours, Minutes, Seconds, Frames, and SMPTE Bits). The
selected unit of measure is shown in the display in brackets, for example <F> for Frames.
Use the Left and Right POSITION buttons to select units.
You can use the Copy Edited feature in the Utility Menu to create a new cut that contains only the audio
material between the HEAD and TAIL pointers. By deleting the original cut, you then free up recording
time on a drive by eliminating the audio material that is no longer needed.
