Background Noise Reducer

When you record a podcast, you want listeners to focus on ideas, not the room. But real studios are rare: there is often an air conditioner somewhere, a computer fan a few feet away, or a faint electrical hiss from a preamp. The Background Noise Reducer is built for exactly these realities. It is a minimal tool that does one thing well: remove background noise from spoken-word recordings without over-processing your voice.

Under the hood, it combines practical, battle-tested techniques inspired by AI denoisers with classic signal processing. Auto mode applies a sensible stack for most recordings. For hum, it notches out 50 Hz and 60 Hz mains interference and their harmonics. For fan noise, it shapes the spectrum toward the vocal range so steady broadband noise sinks under the dialogue. For hiss, it gently limits excessive high-frequency energy while keeping sibilants intelligible. The result is a clear, comfortable track that still sounds like you.

This is not a full editor. It will not remove filler words, trim silence, or correct mistakes. Instead, it complements your existing workflow in DAWs or editors like Audacity, Adobe Audition, Logic Pro, or Hindenburg. Think of it as lightweight podcast editing software you can open in a browser whenever background noise sneaks into an interview or solo episode. Upload, reduce, and download a clean WAV you can drop into your session.

Because processing happens in your browser, your audio stays on your device for privacy. There is no login, no upload queue, and no watermarks. Whether you are producing a weekly show or recording an urgent update on the road, you can remove background noise quickly and move on.

The fastest way to remove background noise is to prevent it at the source, then let software do the last 10–20%. These tips help you get there consistently:

• Record close to the microphone at a steady level. Strong signal beats noise. Aim for peaks around −12 dBFS so you are not pushing preamps into hissy territory.
• Turn off or move away from steady noise makers. If you can, switch off AC during a take or move the mic so a computer fan vents away from it.
• Choose the mode that matches your problem. For low buzz in North America, try Hum (60 Hz). In many other regions, Hum (50 Hz) fits mains power. If it just sounds like air, Fan or Auto is a good start.
• Start with moderate strength. If noise is still obvious, increase in small steps. If speech starts to lose sparkle or air, back the strength down.
• Compare A/B before committing. Listen to quiet passages and breaths, not just sentences. The goal is a pleasant noise floor without artifacts.
• Use this alongside your DAW or favorite podcast editing software. After you remove background noise here, do trims, fades, music, and mastering in your editor.
