The sound effects on "Money" were created by splicing together Waters' recordings of clinking coins, tearing paper, a ringing cash register, and a clicking adding machine, which were used to create a 7-beat effects loop (later adapted to four tracks to create a "walk around the room" effect in quadraphonic presentations of the album). At times the degree of sonic experimentation on the album required the engineers and band to operate the mixing console's faders simultaneously, to mix down the intricately assembled multitrack recordings of several of the songs (particularly "On the Run").
