Most audio problems are cheaper to prevent than to repair. A noise remover can do a lot with a recording made in a spare bedroom, but it works best when the voice was captured clearly in the first place. You don't need a studio for that. You need a quiet moment, a sensible microphone position and a few habits.
This is the checklist we'd run through before pressing record anywhere that isn't a treated room.
1. Choose the room by ear, not by looks
Walk around your home and clap once in each room. If you hear a ring or a flutter after the clap, that room will add echo to your voice. Echo is the hardest thing to remove later, because it is part of the voice itself rather than a separate sound on top of it.
- Soft rooms win. Bedrooms, a room with a sofa and curtains, or a walk-in wardrobe full of clothes usually sound far better than a kitchen, bathroom or empty office.
- Avoid the middle of a bare room and avoid sitting with your face close to a flat wall or a window.
- Listen to the quiet. Sit still for thirty seconds and notice what you hear: a fridge, the boiler, traffic, a neighbour's television. Pick the room where that background is lowest.
2. Switch off what hums
Steady noise is the easiest kind to remove afterwards, but there is no reason to record it if you can stop it.
- Fans, air conditioning and heaters (or at least set them to their quietest setting).
- The fridge, if it is in the same room and you are recording for a short while. Put a note on the door so you remember to switch it back on.
- Laptops with loud fans: close heavy browser tabs and apps, or move the laptop further from the microphone.
- Phones on silent and face down, notifications off on the computer you are recording with.
3. Get the microphone close
Distance is the single biggest factor in how clean a recording sounds. The closer the microphone is to your mouth, the louder your voice is compared with everything else in the room, and the less the room itself is heard.
- A hand's width or two away is a good starting point for most desk microphones, slightly off to the side so your breath doesn't hit it directly.
- Headset and lavalier microphones are excellent for noisy homes, because they stay close however you move.
- A phone can do a good job if you hold it or prop it close to your mouth, rather than leaving it on a table across the room.
A pop filter or foam cover helps with hard "p" and "b" sounds. It is cheap and worth having.
4. Set the level with headroom
Ask the person recording to speak at their normal energy, including a laugh or an emphatic sentence, and watch the meter.
- Aim for loud parts well below the top of the meter. A recording that is a little quiet is easy to raise later; one that hits the ceiling is clipped, and clipping is damage, not noise.
- Turn off automatic gain if your recording app or interface offers it. Automatic gain raises the background every time you pause, which makes the noise pump up and down.
- Record at 48 kHz if you have the choice and the result will end up in a video. For audio-only work 44.1 kHz is also fine; just stay consistent within a project.
5. Wear headphones and do a test take
Record ten seconds, then play it back on headphones. Listen for:
- Hiss that wasn't obvious in the room.
- Buzz or hum, often from a cable, charger or USB hub. Try a different socket or unplug the charger.
- Clothing rustle, a creaky chair, or the desk being tapped.
- Your own breathing on the microphone, which usually means it is pointed straight at your mouth.
Fixing one of these now saves an hour later.
6. Leave a few seconds of silence
Start every take with three to five seconds of the room doing nothing. It gives you a clear reference for what the background sounds like, makes the before-and-after easy to judge in a preview, and gives an editor somewhere clean to cut.
7. Record each voice separately when you can
If two or more people are speaking, separate microphones on separate tracks are worth the extra setup. You can then fix one voice (a louder room, a noisier laptop) without touching the others, and you can balance their levels properly. Remote guests can usually record their own side locally and send you the file afterwards.
8. Save the original, untouched
Keep the raw recording as it came out of the recorder or app, in the best quality it offers. Don't run it through a messaging app or a social platform first: those compress the audio and throw away detail that a noise remover would have used.
After recording: clean, then edit
Even with all of the above, a home recording will usually have some background left: a faint fan, distant traffic, the soft hiss of a budget microphone. That is the part a noise remover handles well.
- Open the noise remover for audio or go straight to the tool and drop in your file.
- Choose a loudness target for where it is going: Podcast for shows, YouTube for video.
- Preview the original against the cleaned version at the same moment, then download.
Our speech AI keeps the voice and removes the sound around it, steady or changing. It does not remove echo, which is why the room choice at the top of this list matters so much.
A one-minute checklist to keep by the microphone
- Quiet room, soft furnishings, not facing a bare wall.
- Fans, heaters and noisy devices off; phone on silent.
- Microphone close, pop filter on.
- Levels with headroom; automatic gain off.
- Headphones on; ten-second test take.
- A few seconds of silence at the start.
- Original file saved before anything else touches it.
