WAVEFORM EDITOR
511
Figure 44-3: The Waveform Editor provides complete destructive
editing of surround audio files.
When copying and pasting portions of a surround
audio file in the Waveform Editor, the source
material in the clipboard must have the same
number of channels as the paste destination, with
the exception that mono-to-stereo and stereo-to-
mono conversions are supported. See “Waveform
Editor preferences” on page 522.
To apply Spectral Effects (Audio menu), such as
formant-corrected pitch-shifting, to a surround
audio file, all channels must be selected.
The Waveform Editor Time Rulers
The Waveform Editor can display time rulers in any
of Digital Performer’s four time formats: measures/
beats, real time, SMPTE time code, and/or
samples. You can show and hide any combination
of these four rulers using the “Time Formats
window” on page 90. The measure|beats|ticks
ruler displays time according to the tempo map, if
any, and the soundbite’s sync point, if it has one.
Below is a summary of how the measure ruler
displays time in the Waveform Editor:
If a soundbite has no tempo map or sync point, the
measure ruler places measure 1, beat 1 at sample
number 0 and displays measures and beats based
on a default tempo of 120 BPM. If the soundbite
has a tempo map, the time ruler follows the tempo
map. If the soundbite has a sync point, the time
ruler places measure 1, beat 1 at the sync point.
Scrolling
You can, of course, use the horizontal and vertical
scroll bars to move around in the file. You can also
scroll horizontally by dragging the close-up lens in
the overview as shown in Figure 44-1 on page 504.
Here are some keyboard shortcuts for scrolling:
Zooming
The waveform display has very flexible zooming
capabilities. You can zoom all the way out to see the
entire audio file; conversely, you can zoom all the
way in to make precise edits on individual samples,
as demonstrated below in Figure 44-4.
