Correlation between mean time lag, signal amplitude and signal duration

A macro was used to evaluate the timing and signal amplitude of four males acoustically interacting in a chorus. Recording channel 2 - 5 contains the evaluation of microphone recordings of individual males. Channel 6 refers to the evaluation of the microphone positioned in the middle of the chorus. CP = chirp period. This data was used to correlate the average time difference between individual signals with the signal amplitude recorded by the central microphone (shown in figure 4C). This data was also used to calculate the correlation of the time lag of chirps produced by male individuals with the duration of their chirps (Figure 5).
