Choosing channels for audio analysis
The audio analysis tools follow the currently
focused audio input or output. (See “Channel
focus and settings” on page 70.) If you focus a
mono channel (e.g. Analog 3), its corresponding
stereo pair will be displayed (Analog 3–4).
Scoping host software audio output
If you want to scope audio output from your host
software, send your host’s output to an 828x output
pair, and then set the focus on that output pair.
FFT AND SPECTROGRAM DISPLAY
FFT and spectrogram information can be
displayed in the Filter response display section in
the EQ tab (Figure 9-10 on page 80) or as a
separate window (Figure 9-29 on page 96) opened
from the Devices menu (Figure 9-27).
