sound card hardware will 'clip' the samples which means that the analyzer no longer gets the proper
information about the dynamic characteristics of the music. If the input is level adjusted too low, the
input may no longer have enough 'resolution' to enable a good trig analysis. A well-adjusted input will
show a graph that never 'max-out', thus clipping the input - but still have enough dynamics for a good
analysis.
Note that the Sound Analyzer draws the graph in yellow when the sample is close to clipping level
and in red when the sample is clipped. The analyzer also shows a clip indicator in the lower left corner
even when the real-time view is not used.
Audio Analyzer - Real-time view
Adjusting the trigging sensitivity
Once the input level has been adjusted - there are various parameters that may be adjusted to decide
how the analyzer finds the trig information in the music. Adjusting these parameters is best done with
the analyzer in time-line view (View -> Show -> Input -> time-line). The time line view shows the
last 5.8 seconds of 'dynamic' information contained in the audio in.
The analyzer detects trig information by comparing the current input level with the previous input
levels. If the current level exceeds the previous levels by a certain factor (see below) the analyzer
indicates a trig. Detecting trigs this way ensures that the trigs are found independently of the actual
input level of the sampled sound. Trigs are shown on the graph as yellow lines. There are various
factors that may influence whether the analyzer detects a trig or not.
Noise Level - a noise threshold limit may be applied. The threshold may be used to filter out noise, or
may be used to filter out trigs that appear below a certain threshold level. The range of the noise
threshold may be set from low to high in the Trigger -> Noise level menu. The threshold itself may
be adjusted using the middle drag bar or by dragging the blue line representing the threshold directly
on the graph.
Trig Decay - the trig decay is the time that must pass from one trig until the next can occur. The
decay time may be adjusted using the leftmost drag bar from between approx. 0.05 to 0.6 seconds.
Trig Sensitivity - the trig sensitivity regulates how much the current sample must exceed the previous
sample in order to detect a trig. The sensitivity is set using the rightmost drag bar, and ranges from
