Growing Intensity Fuzz Warble

This ambient sound starts with a low, fuzzy hum and gradually increases in intensity, evolving into a warbling noise. The sound could be imagined as emanating from an electronic device or a futuristic machine, slowly warming up to full power. The gradual increase in volume and pitch adds a sense of building tension and anticipation, making it suitable for use in scenes that require a rising sense of urgency or technological progression.
