'''Audio signal flow''' is the path an [[sound|audio]] signal takes from source to output, including all the processing involved in generating audible sound.<ref>{{cite book | title = Pro Tools 6 for Macintosh and Windows | author= Steven Roback | edition = 2nd | publisher = Peachpit Press | year = 2004 | isbn = 978-0-321-21315-0 | page = 303 | url = http://books.google.com/books?id=6kcD7mPdaXwC&pg=PT319&dq=%22audio+signal+flow%22&lr=&num=20&as_brr=3&ei=Fe47S-TAFYrSkwTjy5DMAQ&cd=2#v=onepage&q=%22audio%20signal%20flow%22&f=false }}</ref>

== CD Playback Example ==

The following example will trace the signal flow of a typical home stereo system while playing back an audio CD.

The first component in the signal flow is the CD player, which produces the signal. The output of the CD player is connected to an input on a receiver. In a typical home stereo system, this connection will be analog and unbalanced at consumer line-level of -10dBV using RCA connectors. By selecting the proper input on the receiver, the signal is routed internally to an amplifier which boosts the signal voltage from line-level to the voltage required by the speakers. The output of the amplifier is then connected to speakers, which convert the electrical signal into acoustical sound.
