Digital Audio Workstations
• Editing in the DAW environment is more precise, non-destructive and relatively simple
• Using many of the same edit commands as word processors
• “Cut, Paste, Copy, Delete, etc.”
• Recordings may be shortened, lengthened, re-arranged, combined, etc.

Tape editing
• DAWs tend to simulate analog tape editing in their user interface and build upon that familiar foundation
• Analog tape editing used “cut & splice” techniques to achieve the effects of editing

Tape editing• Locating the precise location to cut the tape was
difficult• Involved moving the tape slowly over the
reproduce head

DAW editing
• Editing on a computer based DAW allows edit points to be determined visually
• Some DAWs include a “scrub” function that allows the operator hear the material as the cursor is slowly moved across the wave form
• Scrubbing simulates the effect of slowly rocking tapes across the reproduce head

DAW editing
• Computer based DAWs offer tools for changing levels and mixing relative levels
• In some software, on-screen faders can store level adjustments and reproduce them on playback
• On-screen “envelope markers” can provide a visual referent for audio levels and adjustments

DAW editing
Most DAWs present a common look to their on-screen interface making it easier for operators to use a variety of applications for
various purposes
Fundamentals of Audio Production Chapter 8

DAW editing
• Control surfaces provide familiar tactile interfaces for editor operators– Faders control audio levels– Shuttle controls for record, playback, rewind,
fast forward, etc.– Jog control to scroll or scrub
