Display Waveform as Sample Bits
You can switch from the usual representation of the waveform, to one that shows the
structure of the recorded digital data, at high magnification levels on the detailed
waveform display. You do this by selecting View > Show as Sample & Hold. This can be
useful when eliminating clicks and pops from your recordings, for example.
Thanks to the clever use of oversampling techniques and lowpass filters at the D/A
conversion stage, the stored sample bits (on the right) are ultimately converted into a
signal waveform, more like the one shown to the left.

Monitoring Sample Playback
There are various ways to play back the audio sections visible in the Sample Edit
window, allowing you to hear audio during edits. Playback occurs independently of the
song position. If you’d like to hear the selected audio passage in the context of the
song, just use the Transport controls, as usual.
Selecting the Audio Output
The small boxes below the loudspeaker symbol allow you to select the hardware and
output channel that you want to use for monitoring.
Set the number of the desired output in the Channel box under the loudspeaker
symbol. Use the Device box just below it to choose between different kinds of
hardware, if you have more than one type installed (if you don’t, this switch will not
appear.).
Playback from the Overview
Monitoring playback from the overview display is performed in exactly the same way
as Regions in the Audio window. Simply click-hold at the point you want playback to
begin. Releasing the mouse causes playback to stop. You can also start monitoring
from any position by double-clicking on the overview.
Playing the Whole Audio File
The Play/Stop All key command allows you to play back the whole file, regardless of the
current selection.
