Create Sound Effects#

Generate realistic sound effects, music samples, and audio loops using Stable Audio Open model. This tool excels at creating short audio clips, drum beats, instrument riffs, ambient sounds, and foley recordings.

Overview#

  • Text-to-audio generation
  • Variable duration control (1-120 seconds)
  • Multiple sample generation
  • Seed control for reproducibility
  • Configurable generation parameters

Quick Start#

  1. Visit Eden Create: Create sound effects tool
  2. Enter your audio description
  3. Set desired duration
  4. Click "Create"

See API Reference section below for API usage examples.

Ask an Eden agent to "Create sound effects".

Basic Usage#

Required inputs:

  • Text prompt describing the desired sound
  • Duration (1-120 seconds)

Optional settings:

  • Number of samples (1-4)
  • Negative prompt
  • Steps (16-200)
  • Seed value

Technical Guidelines#

The model is optimized for short audio samples up to 47 seconds, though it supports generation up to 120 seconds. Best results typically come from:

  • Duration: 5-30 seconds
  • Steps: 50 (default) for balanced quality
  • CFG: 5.0 (default) for prompt adherence

Input Best Practices#

Structure prompts using the following format:

Genre: [type] | Styles: [description] | Instruments: [list] | Moods: [descriptors] | BPM: [tempo]

Example:

Genre: Trap | Styles: well arranged | Instruments: tap delay marimba arp, Shaker, Rim shot, 808 Kick | Moods: Ethereal, Transcendent | BPM: 130

Technical Details#

  • Base Model: Stable Audio Open
  • Training Data: Freesound and Free Music Archive
  • Maximum Duration: 120 seconds
  • Optimal Duration: Up to 47 seconds
  • Sample Rate: 44.1kHz

Common Issues and Solutions#

  1. Poor Quality Output

  2. Increase steps (50-100)

  3. Adjust CFG value (3.5-7.0)

  4. Use more specific prompt structure

  5. Generation Too Long

  6. Keep duration under 47 seconds for optimal results

  7. Split longer sounds into multiple generations

  8. Unclear Results

  9. Use structured prompts with Genre/Style/Instruments
  10. Include specific BPM if relevant
  11. Add mood descriptors for better context

Use Cases#

Sound Design#

  • Film and video game audio
  • Podcast intro/outro music
  • Sound effects for animations
  • Ambient background music

Tips for Best Results#

Prompt Engineering#

  • Be specific about genre and style
  • Include instrument details
  • Specify tempo when relevant
  • Add mood descriptors

Parameter Tuning#

  • Start with default settings
  • Adjust steps for quality vs. speed
  • Use CFG to control creativity
  • Experiment with different seeds

Next Steps#

Once you have your generated audio:

  1. Review Quality - Listen for artifacts or issues
  2. Adjust Parameters - Fine-tune for better results
  3. Generate Variations - Create multiple samples
  4. Export and Use - Download in your preferred format
