What it removes
Which background noises does SimpleClean remove from audio?
SimpleClean targets the steady, continuous background noise that hides inside most recordings — the kind you barely notice while recording but can’t unhear in playback. Upload a sample, and the AI model reduces it while keeping the voice crisp and natural.
Electrical hiss and hum
Fine continuous hiss and lower tonal hum picked up from microphones, interfaces, or cables.
Room tone and ambient noise
The low ambient “air” of a quiet room that keeps every pause from feeling like true silence.
White noise
Broad, steady white noise from fans, air conditioners, or computer cooling in the room.
Microphone background noise
Desk vibrations, typing, chair squeaks, and other low-level capture noise near the mic.
Distant traffic or HVAC rumble
Deeper rumble that drifts in from outside or from forced-air systems in home studios.
Where they show up
Recordings from Zoom, Google Meet, Teams, Audacity, iPhone voice memos, or any recorder — upload, preview the cleaned audio side by side, and download when it sounds right. Podcast and voiceover takes, interviews, and meeting recordings all follow the same one-file workflow.
What it does not promise: transient spikes like hand claps, door slams, or hard consonants are brief bursts, not steady noise, so they are handled less reliably — the same honest limitation covered in the FAQ below. For steady hiss, hum, and room tone, expect a cleaner track with the voice intact. Not sure which category your recording falls into? Check the audio noise reference for the full diagnosis table.
