01Main Sound Prompt

PASTE THIS AS YOUR SOUND PROMPT A Medium Wood object Whooshing with Moderate force, sounding Dry and Crisp Recorded in a Small Room at Close distance with Short Room Tail. Background: Isolated No Background. Perspective: Neutral Observer. Attack: Instant Sharp Attack. Tail: Short Decay. CATEGORY: Whoosh Transition for a Video Transition FEEL: Satisfying and Crisp LENGTH: 1 to 2 Seconds STEREO: Centred Mono EXCLUDE: No Music TOOL: Any Text to Audio Tool in Text to Sound Effect

02Material and Action Brief

MATERIAL AND ACTION BRIEF - THE RULE THAT FIXES MOST SFX PROMPTS DO NOT NAME THE SOUND. DESCRIBE WHAT PHYSICALLY HAPPENS. A door sound is vague. A heavy wooden door closing firmly in a small room is a sound. MATERIAL: Wood ACTION: Whooshing FORCE: Moderate SIZE: Medium - size changes pitch and weight more than anything else TEXTURE: Dry and Crisp THE FORMULA: size plus material plus action plus force plus space Every one of those five words changes the result. Leaving one out is where vague sounds come from. AVOID: No Music

03Space and Perspective Brief

RECORDING SPACE: Small Room REVERB: Short Room Tail DISTANCE: Close STEREO: Centred Mono BACKGROUND: Isolated No Background PERSPECTIVE: Neutral Observer SPACE IS WHY A SOUND FEELS REAL OR FAKE The same impact in a small room and a cathedral are different sounds, not the same sound with effects. GENERATE DRY WHERE YOU CAN - you can always add reverb later, you cannot remove it MATCH THE PICTURE: the space in the sound must match the space on screen ISOLATION: for a library, generate Isolated No Background so the sound stays reusable

04Layering and Edit Brief

LAYERS: Two Layers arranged as Whoosh Plus Impact ATTACK: Instant Sharp Attack TAIL: Short Decay BIG SOUNDS ARE BUILT, NOT FOUND A cinematic impact is usually a low sub, a mid body and a high transient generated separately and stacked. GENERATE EACH LAYER ALONE then combine them in your editor THE TRANSIENT SELLS IT: the first few milliseconds decide how the sound reads LAND ON THE FRAME: place the attack on the cut, not just before or after POST: Normalise Peaks FORMAT: WAV Uncompressed at 48 kHz Video Standard

05Library and Rights Plan

PRODUCE: 3 Variations WHY VARIATIONS: repeated identical sounds are the fastest way to make video feel cheap FOOTSTEPS AND UI especially need three to five variants rotated NAMING: Material Action Force A GOOD NAME IS FINDABLE IN TWO YEARS - describe it, do not number it FORMAT: WAV Uncompressed at 48 kHz Video Standard - 48 kHz matches video, 44.1 kHz matches music POST: Normalise Peaks PLATFORM: Reels and TikTok RIGHTS: Check Your Plan Allows Commercial Use Commercial use depends on your plan tier - verify before publishing RESELLING A GENERATED SOUND PACK is a different question from using sounds in your own work - check the terms first Keep records of your prompts, tool and dates

The One Rule That Fixes SFX Prompts

Describe, do not nameA door sound is vague. A heavy wooden door closing firmly is a sound.Core rule
Size sets the pitchSmall is high and tight. Massive is low and slow. Say which.Biggest lever
Material sets the toneWood, metal and glass behave completely differently on impactCharacter
Force sets the energyA light tap and a violent slam are not the same sound louderDynamics
Space sets the realityThe room is part of the sound, not an effect added afterRealism
Five words, every timeSize, material, action, force, space. Miss one and it goes vague.The formula

Building Big Sounds

Layers, not luckA cinematic impact is a sub, a body and a transient stackedHow it is done
Generate each aloneMake the layers separately and combine them in your editorMethod
The transient sells itThe first few milliseconds decide how the whole sound readsDetail
Low gives weightA sub layer under any impact makes it feel physically heavyTrick
High gives clarityA crisp top layer makes it cut through a busy mixTrick
Dry firstGenerate dry, add reverb later. You cannot remove reverb.Order of work

Making It Sound Real

Vary repeated soundsIdentical repeated footsteps are the fastest tell of cheap audioCritical
Three to five variantsRotate them so no two consecutive steps matchHow many
Match the pictureThe space in the sound must match the space on screenContinuity
Distance is not volumeA far sound has less high end, not just lower levelPhysics
Land on the framePlace the attack on the cut, not near itEditing
Less is moreOne well placed sound beats five competing onesRestraint
