Issue

The Peak, Valley, and Tip conditions in the FeatSrch component are not always correct for low-frequency signals. For example, a 1 Hz tone playing for 10 seconds should count 10 peaks, 10 valleys, and 20 tips but 13 peaks, 12 valleys, and 17 tips were actually recorded. Be careful when using these conditions in the FeatSrch component with low-frequency signals (less than 5 Hz).
