	%X In this work, a method of time delay estimation for 
dual-channel acoustic signals (speech, music, etc.) recorded under 
reverberant conditions is investigated. Standard methods based on 
cross-correlation of the signals show poor results in cases involving 
strong reverberation, large distances between microphones and 
asynchronous recordings. Under similar conditions, a method based 
on cross-correlation of temporal envelopes of the signals delivers a 
delay estimation of acceptable quality. This method and its properties 
are described and investigated in detail, including its limits of 
applicability. The method’s optimal parameter estimation and a 
comparison with other known methods of time delay estimation are 
also provided.
