Learn to generate unique and original soundtracks by specifying vibe, style, purpose, energy, and tempo.
Try it in the app
Generate unique and original soundtracks in a few simple steps.
Generate soundtrack (beta) allows you to generate soundtracks by selecting key creative inputs such as vibe, style, purpose, energy, and tempo. Your selected inputs work as a guide in composing soundtracks that match specific moods, genres, and use cases, whether it's background music, game soundtracks, audio for podcasts, or soundscapes for meditation.
When generating soundtracks, you can upload a video to receive a suggested prompt you can customize, or start from scratch by crafting a custom prompt without a video component.
Poznámka:
On the Generate soundtrack page, the left panel contains a sample prompt with colored text representing different soundtrack generation attributes.
Start composing the prompt by removing or adding the preloaded tags for each attribute.
Tip:
To remove all preloaded tags, select the Clear Prompt button.
Select tags from the following available attributes to add to the prompt.
- Vibe: Represented by purple text in the prompt. Use this to define the overall mood or emotional tone for soundtrack generation.
- Style: Represented by blue text in the prompt. Use this to define the genre or instrumentation for soundtrack generation.
- Purpose: Represented by green text in the prompt. Use this to define the intended use case or context for soundtrack generation.
To add your own tags for any of the attributes, use descriptive adjectives.
Set the energy of the soundtrack by choosing from the following options:
- Low: Soft and calm
- Medium: Balanced with a steady rhythm
- High: Fast and lively
Set the tempo to define the speed or pace of the soundtrack for the generation. There are the following options to choose from:
- Slow: Low-paced and calm
- Medium: Steady, balanced, and moderately paced
- Fast: Quick, energetic, and high-paced
Use the Duration section to increase or decrease the duration of the generated soundtrack.
Select Generate. You'll get four different variations of the soundtrack.
Preview each soundtrack and highlight the variation that you want to download, then select Download.
The soundtrack will be downloaded in WAV format.
Tip:
If your soundtrack isn’t matching your expectations, it may be due to conflicting input terms. For example, setting the Vibe to calm and the Style to heavy metal can lead to unpredictable results, often favoring one over the other.
You can adjust the Vibe to better align with your desired mood, then refine the Style to complement it, and avoid mixing terms that represent opposite emotional tones or musical genres.
