pocket sfxhow to record sound effects at home
You don't need a studio to record good sound effects. You need a quiet room, a microphone, sensible levels and lots of variations. This guide goes through it in order, from the room to the finished, layered sound.

1. the room matters more than the mic
Most home recordings don't sound bad because of the microphone. They sound bad because of the room: echo from bare walls and background noise from things you stop hearing after a while.
- Pick the smallest room with the most soft stuff in it. A bedroom or a walk-in closet with clothes beats an empty kitchen.
- Hang a blanket or a duvet behind and around the spot where you perform. It kills a lot of echo for free.
- Turn off what hums: fridge, fans, the heating, the computer's own fans if you can move it away.
- Record when it's quiet outside. Late evening often beats the middle of the day.
- Listen to ten seconds of "silence" on headphones before you start. Whatever you hear, the mic hears too.
2. the microphone
Any decent microphone works for a start, including a USB mic. A few things matter more than the model:
- Distance. Closer is drier and louder compared to the room. Start about a hand's width to 30 cm away from the prop and move from there.
- Angle. Aim at where the sound happens: the zipper pull, the heel of the shoe, the hinge of the door.
- Dynamic or condenser. A dynamic mic picks up less room and is forgiving with loud hits. A condenser catches more detail in quiet sounds like cloth and paper, and more of the room too.
- Handling noise. Put the mic on a stand. Holding it in the same hand as the prop is how bumps end up in every take.
3. levels: leave headroom
Set the input gain so the loudest takes peak somewhere around -12 to -6 dBFS. That leaves room for the surprise hit that's louder than the rest. A clipped take can't be repaired; a quiet one recorded at 24-bit can simply be turned up later.
Record in 24-bit (or 32-bit float). 48 kHz is the usual rate for games and video. 96 kHz is only worth it if you plan to pitch sounds down a lot.
4. perform lots of variations
The best sound effects libraries have many versions of every sound. Record more than you think you need:
- Vary the intensity: soft, medium, hard.
- Vary the speed: a slow door, a fast door, a door slammed in anger.
- Vary the material: the same footstep on wood, gravel, carpet, tiles.
- Leave a short silence between takes so each sound can ring out.
- For sounds a player or viewer hears often (footsteps, hits, clicks), aim for five to ten usable variations. Played at random, they never sound repetitive.
5. name and sort as you go
A folder full of Recording 37.wav is where sounds go to be forgotten. Name files by what they are, with a number: Door Slam_001.wav, Door Slam_002.wav. Sort them into folders by sound or material. Doing this while you record takes seconds; doing it a week later takes an afternoon.
6. trim and fade every take
Each sound effect should start right at the sound and end when its tail has died away. Cut the silence before and after, then add short fades: a few milliseconds of fade in stops a click at the start, and a fade out of tens of milliseconds makes the tail end smoothly instead of stopping dead. Keep the original recording somewhere, in case you trim too much.
7. layer for bigger sounds
Big sounds are rarely one recording. A heavy door is a slam for the impact, a creak for the body and maybe a low whoosh to give it weight. Line the layers up so the attacks hit together, balance their volumes, and crossfade where one sound hands over to the next. Then export the mix as one file.
8. file format
Keep your library in WAV: 48 kHz, 24-bit, mono for most single sounds. Every game engine, editor and DAW reads it. Compress to OGG or similar only at the very end, if your game or platform needs it.
doing all of this with pocket sfx
Steps 4 to 8 are what Pocket SFX does for you. In auto mode you perform and it records: each sound becomes a separate take, trimmed, faded and named from a template, in a real folder on disk. You sort takes by dragging, fix trims and fades by dragging, and layer takes on a timeline that exports numbered WAV versions. Steps 1 to 3 are still up to you and your blanket.
