The spread and coloration of pair-wise panned virtual sources are
investigated in listening tests. The results are compared with results
from corresponding simulations using a binaural auditory model. The
results show that amplitude panned virtual sources produce highly
conflicting cues at frequencies between 700 Hz and 2 kHz, and that they
are localized according to different cues depending on signal attributes.
A DSP-based method for enhancing the virtual source quality is proposed.
