 Goldstein thought "Irreplaceable" sounded "a bit old-school"; an eighth note delay echo was placed on the song's lead vocal at 341ms, using the "Echo Farm" plug-in software.For the backing vocals, Goldstein used "Echo Farm" with a quarter note delay at 682ms and Sony's "Oxford Dynamics" compressor/limiter in dual-mono mode.The compressor was placed in Classic setting, to emulate the LA-2A leveling amplifier, and the Warmth button used to add harmonics.
