About this sound
An AI-generated sound effect: “Deep, low-frequency resonant rumbling of large volumes of dense, slow-moving heavy fluid, with thick viscous sloshing texture, deep submerged weighty thuds and muted, dampened wave movement with no sharp high-end frequencies, no voice, no music”. 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 (9.5/10): This clip matches the brief perfectly, featuring only slow heavy viscous fluid rumble with no high-end harshness, no speech, music or unwanted recording artifacts.

- Do I have to credit BudgetPixel to use "Thick Viscous Fluid Rumble"?
- 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.

- "Thick Viscous Fluid Rumble" runs 3.9 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 "Thick Viscous Fluid Rumble" in a monetised YouTube video?
- Yes. Monetised video is explicitly permitted.
