A study of rendering natural instrument sounds and vocals as an ensemble is presented. Using a single channel musical recording, a multi-channel signal is created by introducing delays and rendered in spatially distributed loudspeaker array. Three listeners participate in a listening experiment. We observed that the perceived width of the ensemble varies with the signal timbre. We find that spectro-temporal properties of the musical instruments play a significant role in the perception of source width. On an average, sustained sounds (like vocal) create wider percept than transients like percussion. Also, low pitched sounds (like male bass voice, saxophone, tuba) create wider percept than high pitched signals.
