Iris 2 | WAVEFORM OVERVIEW Page 39

WAVEFORM OVERVIEW

At the top of the spectrogram is the Waveform Overview. This displays the entirety of your

sample for quick overview and navigation. If you are zoomed in to a part of the sample on

the spectrogram itself, that area will appear as boxed in the Waveform Overview. You can

use your mouse to move this boxed area across your sample to maintain zoom level while

scrolling across.

THE SPECTROGRAM AREA

The spectrogram displays selected parts of the spectrum in a blue/green color, and any

ﬁltered part of the spectrum is represented in grey. Selections are made using the tools

listed in the following section. You have the option of viewing the spectrogram with rulers

for frequency and time (as it is displayed above). To show/hide these rulers, or change their

scaling or units, see the Options Panel.

Within this area, you can also view a traditional waveform representing amplitude across time,

like you would see for audio ﬁles recorded into an audio editor. You can actually view both the

waveform and spectrogram in combination by adjusting the Waveform/Spectrogram Display

Slider at the bottom-right corner of this area.

As a sample plays back, solid white lines or ‘playheads’ will stream across the sample for each

voice, illustrating what part of the sample is playing back, the playback speed, and direction.

SPECTROGRAM AREA SAMPLE CONTROLS

In addition to the Playback, Pitch Mode, Loop, and Retrigger controls in the sample panel,

there are ﬁve sample controls located in the spectrogram area, four of which have visual

indicators on the spectrogram itself. All of the numeric value controls for these parameters

are located just beneath the spectrogram, and are represented in samples for maximum

resolution and ﬁne control:

Loop Start and End: If you have set your sample to Loop, you may want to adjust the start and

end points for the loop. You can adjust these with the two “handles” (indicated by blue arrows)

appearing between the spectrogram and the Waveform Overview. By default, Iris 2 engages

our Intelligent Zero Crossing technology when adjusting loop points using these handles.

This means that any adjustments you make to the beginning or end of a loop point using the

handles will automatically snap to a phase-coherent zero crossing so you won’t get radical
