Record your voice at home: room, mic, edit
Record your voice at home: room, mic, edit
Most beginner guides spend three paragraphs on microphone choices and one line on acoustics. That is backwards. The room is the single biggest variable in a home recording. A $50 USB mic in a good-sounding corner beats a $500 condenser in a live room every time. This tutorial covers the room first, then placement, then the free-software workflow that every other guide stops short of explaining.

What you will get
A clean, noise-reduced mono track ready to share
Step 1: The clap test (do this before you record anything)
Stand in the middle of the room, clap once sharply, and listen. You are listening for two things:
Flutter echo: a rapid ping-ping-ping decay after the clap. This is parallel hard walls bouncing sound back and forth. It will ruin a vocal.
Reverb tail: a smooth wash after the clap lasting more than half a second. This smears words together and is hard to remove in editing.
If you hear either, move to a smaller, more furnished room or treat the walls before recording. A bedroom with a wardrobe, a bookshelf and a carpet scores far better than an open lounge with bare walls.
Step 2: Free acoustic treatment (no panels required)
You do not need foam tiles to get a clean room.
Closet recording: a walk-in closet lined with hanging clothes is one of the best-sounding spaces in a home. The clothes absorb reflections on all sides.
Blanket fort: drape a heavy duvet or moving blanket over a mic stand or a clothes horse to create a low-reflection tent around your head and mic.
Corner position: standing 1 to 1.5 metres in front of a corner (not in it) with bookshelves or a wardrobe behind you kills rear reflections without any gear.
Soft furnishings: a sofa, a rug and curtains all absorb mid-high frequencies. Hard floors and glass are the enemy.
Step 3: Mic placement
Most USB condensers are cardioid: they pick up what is in front of them and reject sound from behind. Use that.
Distance: 3 to 6 inches (7 to 15 cm) from the capsule. Closer gives a warmer, more intimate sound (proximity effect). Further back adds more room.
Height: capsule at mouth level, not chin-level.
Off-axis angle: tilt the mic 30 to 45 degrees away from a straight line between your mouth and the capsule. This is the simplest plosive fix if you have no pop filter. The B, P and T bursts of air travel straight forward; tilting the mic means they miss the capsule.
The pop filter alternative: a pencil taped vertically in front of the capsule splits the air column and costs nothing.
Step 4: Gain staging (this is where most recordings fall apart)
Before you press record, set your input level correctly. The target is peaks hitting between -12 dBFS and -6 dBFS on the recording meter. That range gives you headroom without a quiet, noisy floor.
Too hot (above -6 dBFS or clipping): digital clipping sounds like a harsh, gritty crunch on louder syllables. Unlike analog tape saturation, it cannot be fixed in editing. It is permanent.
Too quiet (below -18 dBFS): raising the level in editing also raises the noise floor, turning a faint hiss into a noticeable one.
In Audacity: open Preferences, set the input device to your mic, and watch the meter while you speak at recording volume. Adjust the input gain (on the interface or in the OS sound panel) until peaks reach roughly -12 dBFS. Do not touch it again until the session is finished.
Step 5: Capture a noise profile before you speak
Every recording space has a noise floor: air conditioning, street noise, computer fan. Audacity can remove it, but only if you give it a sample first.
After pressing Record, stay completely silent for 3 to 5 seconds before you start speaking. Do not move. Do not breathe loudly. That silent section is your noise profile. Record the full take, then stop.
In Audacity:
Select 1 to 2 seconds of the silent section at the start.
Go to Effect, Noise Reduction, and click Get Noise Profile.
Select All (Ctrl+A / Cmd+A) to highlight the entire track.
Return to Effect, Noise Reduction, and apply.
Step 6: Noise reduction settings and what goes wrong
The default Audacity noise reduction settings are a good starting point, but over- processing is the most common beginner mistake. These settings work for most home-recorded speech:
Noise reduction: 12 dB. The slider goes to 48 dB. Stay low.
Sensitivity: 6. Higher values remove more but can eat into consonants.
Frequency smoothing: 3 bands.
What over-processing sounds like: a metallic, underwater, or robotic quality on vowels and sibilants. If you hear it, undo (Ctrl+Z), reduce the dB figure, and apply again. The goal is to lower the noise floor by 10 to 15 dB, not to make silence between words perfectly flat.
After noise reduction, apply Normalize (Effect, Normalize, peak -1 dBFS) to bring the final level up to a standard broadcast level.

Editing cannot fix a bad room Noise reduction removes steady broadband hiss well. It cannot remove flutter echo, reverb tail, or low-frequency room boom. If the clap test reveals problems and you skip treatment, no plugin will save the recording. Fix the room first, every time.
