VoiceSmiths generates custom sound effects and music from a one-line text description: effects from 0.5 to 30 seconds, music from 3 seconds to 10 minutes, instrumental or with vocals. It runs on ElevenLabs' sound and music models, every file can be used commercially, and pricing is a flat number of credits per generation, starting from a $3.99 one-time pack.

Describe it, and hear it
The old sound-sourcing workflow: browse stock sites → audition dozens of clips → worry about licensing → settle. The new one: write one line, get a custom effect seconds later. Music works the same way — describe style, mood and structure, get 3 seconds to 10 minutes of score.
Real generated samples
Everything below came straight out of this studio, unprocessed:
SFX · prompt "Heavy rain on a tin roof with distant thunder" (6s):
SFX · prompt "Two metal swords clashing in a large stone hall, with echo" (4s):
Music · prompt "Tense cinematic score, low strings and taiko drums, builds then cuts sharply" (15s):
Prompting tips
- Describe the scene, not the category: "a heavy iron door slamming in an empty corridor" beats "door sound"
- Add space: "with echo", "in a small room", "distant" strongly shape the acoustics
- Give music structure: words like "builds then cuts sharply" work
- SFX takes an exact duration (0.5–30s); music runs 3s–10min and can be instrumental
Pairing with voiceover
A short video's full audio layer = voiceover + effect accents + background score. All three live in the Voice Studio; line them up in your editor using the subtitle timestamps. For a story with several characters, the audio drama studio casts the voices for you.
FAQ
How does the AI sound effects generator work? Describe the sound in one line, for example "heavy rain on a tin roof with distant thunder", optionally set a duration between 0.5 and 30 seconds, and you get an MP3 a few seconds later. It runs on the ElevenLabs sound effects model through the official API.
Can it make music too? Yes. Describe the style, mood and structure and you get a track from 3 seconds to 10 minutes long, instrumental or with vocals, on the Eleven Music model.
Is it free? The samples on this page are free to play, but generating sound effects or music uses credits; there is no free generation for this tool. Credits start at $3.99 one-time for 150, and each generation shows its flat price on the button before you spend anything. See pricing.
Can I use the sounds commercially? Yes. Effects and music you generate can be used in commercial projects, including film, ads, podcasts and games, under the Terms of Service.
What makes a good sound effect prompt? Describe the scene rather than the category ("a heavy iron door slamming in an empty corridor", not "door sound"), add the space ("with echo", "distant", "in a small room"), and for music give it structure, such as "builds then cuts sharply".
