Can GCC-PHAT be used to detect multiple time-delays (that is, having multiple acoustic sources simultaneously)? The documentation for the
gccphat(sig,refsig) function says that it assumes both
refsig came from a single source.
If it is the case that
gccphat(sig,refsig) can indeed only take into account a single source, can you recommend other approaches I could try to detect multiple sources? I am fairly new to this field so I could appreciate all the help. Thanks.
