Progressive house white noise sweep, 4 seconds

About this sample

This 4-second stereo effect features independent white noise sources on the left and right channels, creating a wide and immersive soundstage. A 4-pole low-pass Butterworth filter sweeps logarithmically from 100 Hz to 16 kHz, producing a smooth, natural frequency rise. The amplitude swells linearly from 30% to full volume, while gentle tanh saturation adds warmth and subtle harmonics. Precise block-based filtering and short fades at the start and end ensure a click-free, polished sweep.

Ideal for progressive house or other electronic genres, this noise sweep works well as a transition or buildup element at various tempos. It can be layered with synths or percussion to enhance energy, but care should be taken to balance its wide stereo image and avoid masking important midrange elements in the mix.
