Signal Flow & The Audio Console
1
Styles of Recording Music
~ 1920’s
✓ ‘live’ recording with all instruments in one, continuous performance
✓ i.e. ‘capturing a performance’
✓ mostly ‘distant’ micing to capture sound

Typical Recording Session ~ 1937

1930’s - present✓use of more than one microphone when recording
✓all instruments not present during original recording •“re-record” to add more instruments (“overdubbing”)
✓modify recording w/ addn’l sources (“effects/reverb”)
✓‘creating a performance’

•musicians listen to previous recording…
•“new performance” is blended with the original performance
•…“play along
“The Sheik of Araby” - Sidney Bichet (1932)
•a new recording is made
“Overdubbing” = adding instruments after original performance

early RCA broadcast ‘mixer’ (~1940s)
first ‘console’ built for modern recording
(~1950)
The Audio Console

takes input (source) signal…
▪ Amplifies = “volume” ▪ Processes = adjust “tone” ▪ Combines = “spatial
positioning” ▪ Balances = “blend” or “mix” ▪ Routes = outputs to
recorder, monitors, etc.
The Audio Console - Basic Functions

⦿ “path” through a system
⦿ important in describing use or function
Signal Flow
Block Diagram • describes a complete system by breaking it into sections or
“blocks” • each “block” has a function and the diagram shows how they
are connected together • shows inputs and outputs
