Audacity Forum

The sound source is a bird in a tree. I want to measure the delay time between two (or four) channels and then delay the cannels by exactly the correct amount and then add all channels, so that the signal is enhanced and noise is reduced.

Let's assume a two-channel track was recorded with two microphones with a large distance between them (10m or more). Is it possible to mark a short piece in this sound track (for example one second), and then calculate a correlation between the two channels and measure the best-fit delay time?
