Chapter 8

Audio Editing

This chapter covers editing of audio files and Playlists. DigiCart/EX 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/EX 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 sets the length of audio that will play prior to TAIL and FADE
OUT edits 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 Arrow buttons to select units.
After Head and Tail editing 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. Deleting the original
cut frees up drive space by eliminating the audio material that is no longer needed.
