Accelerating Heartbeat with Rising Tension

Commercial use needs a Sonilo Pro or Premium plan. Every file is free to download and use in personal, non-commercial projects without attribution, under the library license on this page. Monetized videos, ads, client work, apps, websites and indie games, and distributing the files, are covered from Pro upwards — the same line your plan draws for audio you generate.

You can listen and download MP3 or WAV files directly from this library without signing in. Creating new audio with the AI generator requires a Sonilo account.

MP3 is a compressed file that is convenient for quick previews and smaller projects. WAV is uncompressed and useful when you will edit, layer or process the sound. Both versions of a library sound use the same library license.

Describe the sound in the search box. If there are no matches, choose the AI generation option to bring that description into Sonilo’s sound effects generator. New accounts receive free credits; generation uses credits, and available exports and usage rights depend on your plan.

You can start with a ready-to-download sound or use your description to create a new one in the same product. Sonilo also offers video-to-sound-effects workflows, so you can move from finding a sound to making audio for a particular scene.

Each sound has a permanent detail-page link. Use Share to copy that link, or Embed to copy an HTML audio player with a link back to the sound. Your website editor must allow HTML audio; pasting a URL alone does not automatically embed it.

Sonilo supports video-driven sound effects as well as text descriptions. Open the sound effects product page for the available workflows, or use the developer documentation for API integration. Account generation and API usage follow their own credit and licensing terms.
