Generate custom sound effects from text
# ElevenLabs SFX High-fidelity AI sound effects from text. ## Overview ElevenLabs SFX is a state-of-the-art generative audio model designed to bridge the gap between creative vision and sonic execution. By leveraging advanced latent diffusion techniques, this model transforms descriptive text prompts into high-quality, immersive sound effects and foley assets. Whether you are looking for subtle environmental textures or dramatic cinematic impacts, the model interprets complex acoustic descriptors to deliver professional-grade audio tailored for visual media. Unlike traditional stock audio libraries that rely on pre-recorded files, ElevenLabs SFX generates unique, royalty-free audio from scratch. This allows marketing teams and ad agencies to iterate rapidly, ensuring that the sound design perfectly matches the pacing and tone of their video content. The model excels at capturing nuance, from the specific resonance of a glass shatter to the atmospheric hum of a futuristic city, providing a versatile toolset for modern sound designers and video editors. ## Use Cases * Generating custom foley for social media video ads to enhance brand recall. * Creating seamless background soundscapes for product launch trailers. * Producing unique UI/UX sound effects for mobile app marketing assets. * Designing cinematic impacts and transitions for high-budget digital campaigns. * Developing specific environmental audio for immersive storytelling in branded content. * Rapid prototyping of sound design concepts during the pre-production phase of ad creation. ## Parameters To customize your audio generation, refer to the parameter configuration panel. You can adjust the prompt influence to balance creativity and adherence to your text, toggle looping for background textures, and select specific output formats to match your project's technical requirements. ## Tips for Best Results * Be descriptive: Include details about the environment, the material, and the intensity (e.g., "heavy metallic door slamming in a large echoing warehouse"). * Adjust prompt influence: Use a lower value (0.1-0.2) for more creative, abstract sounds, and a higher value (0.7-0.9) when you need the model to strictly follow specific acoustic characteristics. * Use duration control: For short UI sounds, keep the duration under 2 seconds; for atmospheric beds, utilize the full 30-second capacity. * Iterate with variations: If the first result isn't perfect, tweak a single adjective in your prompt rather than rewriting the entire description. * Consider the output format: Choose higher bitrate MP3s for final exports and PCM formats if you plan on further post-processing in a DAW. ## About ElevenLabs SFX is powered by the eleven_text_to_sound_v2 model, developed by ElevenLabs. As a leader in generative audio technology, ElevenLabs has extended its expertise from industry-standard text-to-speech synthesis into the domain of sound effects, providing a robust, scalable solution for creators who require high-fidelity audio assets on demand.
