  We introduce and analyze Generalized Time Domain Velocity Vector (GTVV), an
extension of the previously presented acoustic multipath footprint extracted
from the Ambisonic recordings. GTVV is better adapted to adverse acoustic
conditions, and enables efficient parameter estimation of multiple plane wave
components in the recorded multichannel mixture. Experiments on simulated data
confirm the predicted theoretical advantages of these new spatio-temporal
features.
