A call is not detected even if its amplitude is above the threshold

Problem

You applied a call definition and detected most calls. However, some calls that look very prominent are not detected.

Solution

In the example below, the second call is not detected even its amplitude is comparable with that other two. Some noise at the end of the call increases the time that the signal is above the Min Amplitude threshold, and this time is above the Max Duration threshold. In such cases UltraVox XT does not detect the call because the signal appears too long to match the criteria of the call definition.

You can solve this issue in two ways:

nIncrease the Min Amplitude threshold, but check that the other calls are still detected.

nIncrease the Max Duration threshold. If necessary, reduce the call duration in the Call Labeling screen. See Adjust frequency and time boundaries in a call
