Oscilloscope
Use the Oscilloscope to view any sound waveforms. These might include music, your voice, or
waveforms played by loudspeakers.
You can choose to trigger each "sweep" from the point where the acoustic pressure level rises or falls
past a selected acoustic pressure levels. To select, click the mouse on the graph at the desired level.
This makes display of repeating waveforms easier to see. To make the trace free-run, click
triggering to "off".
You can freeze the oscilloscope display to better examine a captured waveform by using the
Pause button (two vertical bars) near the top left of the OmniMic screen. Click the Play button
(forward arrow) to begin the display again.
If the waveforms being examined are cluttered with subsonic noise in the room, select the
"10Hz High Pass Filter" checkbox above the graph to remove the lower frequencies from the
display.
