About this sound
An AI-generated sound effect: “Low, subtle undulating hum with a soft grainy texture, faint distant reverberant metal creak that rises slowly then fades gently, thin wisp of atmospheric static that feels cold and hollow, no discernible melody or speech, eerie quiet unsettling ambient texture”. Quality-checked before listing, free for commercial and personal projects — videos, games, podcasts, apps and client work. No royalties — just credit BudgetPixel AI.
Direct file: WAV · 44.1 kHz — both WAV and MP3 are on the download button.
Editor's note (9.0/10): Nearly perfectly matches the brief, containing all requested textural elements with no unwanted speech, music, or disruptive edge artifacts.
Also searched as: creepy background hum · horror ambient texture · distant metal creak · cold static atmosphere

- Do I have to credit BudgetPixel to use "Unsettling Hollow Ambience"?
- Yes — crediting BudgetPixel AI is the one condition of the licence, and downloading still needs no account. Put the credit line from this page wherever your project lists sources: a video description, end credits, show notes, or a game's credits screen.
- What format and length is "Unsettling Hollow Ambience"?
- "Unsettling Hollow Ambience" runs 4 seconds and downloads as WAV at 44.1 kHz, with MP3 on the same download button. Both formats carry the identical licence, so pick whichever your editor prefers — WAV for layering and pitch work, MP3 when file size matters.
- Can I use "Unsettling Hollow Ambience" in a monetised YouTube video?
- Yes. Monetised video is explicitly permitted.
