The original recording was a mess: furnace rumble, water hammer, the distant shriek of a 4 AM freight train. Elias loaded the track into Audacity. He selected a five-second sample of “pure hum” from a quiet corner of the basement. Effect > Noise Reduction > Get Noise Profile. He returned to the full track. OK. The furnace vanished. The water hammer died. The train became a whisper.
Now: the bass.
Elias didn’t flinch. He’d worked on kidnapping tapes in the ’90s. He’d heard worse. Effect > Reverse. He selected the inverted vocal track and hit play.
