Fill Game Levels with Sound
Indie developers generate pickups, menu clicks and looping level ambience while they prototype.

Describe a sound in up to 500 characters and get a sound effect you can play and download. Add a loop, BPM or key when it has to fit music.
The AI sound effect generator turns a text description into a sound effect for 2 credits per run on the Basic plan or higher. Failed runs refund the credits.
Your generated audio will appear here.
The AI sound effect generator creates a new audio clip from a written description, so you can get a door slam, a rain bed or a game pickup sound without digging through a stock library. Type what you want to hear in up to 500 characters: the source, the space and how the sound changes over time. Turn on Loop for a sound that repeats, set a tempo from 1 to 300 BPM, or pick a musical key when the effect has to sit inside a track. Play the result in the page, then download it as an MP3 or adjust the description and run it again.
Name the source, the action and the space in one line, for example 'heavy wooden door slams shut in a small stone room'. Add texture words such as close, distant, muffled or metallic. Ask for one sound per run: if a scene needs footsteps, wind and a door, generate them separately and layer them in your video or audio editor. When a result misses, change one detail at a time so you can hear what each word does.
Three ways to use the AI sound effect generator, from one-off hits to sounds that sit in time with music.
Write the sound the way you would brief a sound designer. The AI sound effect generator reads the whole description, so details about distance, material and motion shape the result.
Up to 500 characters per description.
Focused prompts are easier to adjust.
Change a word and run it again to compare.
Turn on Loop in the AI sound effect generator when you need a sound that repeats, such as rain, room tone, an engine hum or a menu background. Check the loop point in your editor before you ship it.
Off by default; switch it on per run.
Background sound for menus and levels.
Listen before you download.
Set a BPM from 1 to 300 and choose one of 24 major or minor keys, or leave both on automatic. Risers, stingers and rhythmic textures can then line up with the track you are scoring.
1–300 BPM, or blank for automatic.
C to B in major and minor, or Any.
MusicFX Standard, or MusicFX Wild on Pro.
What every run of the AI sound effect generator gives you.
Describe the sound, the setting and how it moves in one prompt.
Ask for a repeating sound for ambience and background beds.
Match a BPM from 1 to 300 and one of 24 keys, or leave it automatic.
Play each result in the page and save it as an MP3 file.
If a run fails, the credits return to your balance automatically.
MusicFX Standard on Basic, or the more experimental MusicFX Wild on Pro.
Six projects where describing a sound can replace a long library search.
Indie developers generate pickups, menu clicks and looping level ambience while they prototype.
Editors create whooshes, impacts and room tone that match the cut.
Hosts make intro stingers, segment bumpers and alert sounds for their shows.
Product teams sketch notification, success and error tones before final sound design.
Producers set BPM and key to make risers and textures that fit a song.
Game masters build rain, tavern and battle ambience for role-playing sessions.
Three steps from idea to audio file.
Write what you want to hear in up to 500 characters.
Leave them on automatic or match them to your project.
Play the result, then save it as an MP3 or adjust and run again.
Answers about prompts, loops, credits and usage rights.
An AI sound effect generator creates a new sound clip from a text description instead of making you search a library. MusicFX at musicfx.net runs one on this page: describe the sound in up to 500 characters, optionally set loop, tempo and key, then play the result and download it as an MP3.
Each run of the AI sound effect generator costs 2 credits with either MusicFX Standard or MusicFX Wild. Generating needs a Basic plan or higher, and MusicFX Wild needs Pro or higher. If a run fails, the 2 credits return automatically.
Free accounts can open the AI sound effect generator and fill in the form, but generating a sound effect requires a Basic plan or higher. On a free account, selecting Generate opens the upgrade options instead of starting a run.
Turn on Loop before you generate. The AI sound effect generator then asks the model for a sound that repeats without a gap, which suits rain, wind, room tone and game menus. Check the loop in your editor, because how cleanly it repeats depends on the sound.
The BPM and key settings tell the model which tempo and musical key the sound should follow. Use them for risers, stingers and rhythmic loops that sit inside a song. Tempo takes whole numbers from 1 to 300; key takes Any or one of 24 major and minor keys. Leave both on automatic if timing does not matter.
The AI sound effect generator downloads results as MP3 files, and you can play each one in the page before saving it. If your editor needs WAV, convert the MP3 in your audio software after downloading.
Commercial use is included with the Business plan. On other plans, generated audio is for personal, non-commercial use. See the Terms of Service for the full conditions.
A sound library gives you existing recordings to search, while an AI sound effect generator makes a new clip from your description. That helps when you need an unusual mix of source, space and texture. For everyday sounds that libraries already cover well, a library may still be the simpler choice.
The AI sound effect generator works from a text description only. It does not accept a video, an image or a reference recording, so describe the moment you need to cover, such as a car door closing at night, and sync the result in your editor.
Use the AI sound effect generator for short sounds, hits and ambience. For a full piece of background music with a melody, use AI Instrumental Generator. For a song with vocals, use AI Music Generator.
