'''Apparent source width (ASW)''' is the audible impression of a spatially extended sound source. Physically, this psychoacoustic impression results from sound radiation characteristics and room acoustical properties. Wide sources are desired by listeners of music. Apparent source width affects the perceived sound of [[acoustic music|unplugged]] [[concert]]s of [[art music]], [[opera]], [[classical music]], [[historically informed performance]] and [[contemporary classical music]], as well as concerts and [[musical theatre]] that use [[live event support]], like [[live sound mixing]], [[sound reinforcement system]]s or a [[public address system]], like [[popular music]], [[rock music]], [[electronic music]] and [[musical theatre]]. Research concerning the ASW comes from the field of [[room acoustics]], [[architectural acoustics]] and [[auralization]] as well as [[musical acoustics]], [[psychoacoustics]] and [[systematic musicology]].
