This audio piece, titled "Sine Wave Sweeps through Low-Pass Filter," is a unique blend of synthesized sounds and analog elements. The audio begins with a sine wave, a smooth and pure tone generated by a voltage-controlled oscillator (VCO), which serves as the foundation of the sound structure. This sine wave then sweeps through a low-pass filter, which is a type of voltage-controlled filter (VCF) that allows lower frequencies to pass while attenuating higher frequencies. As the sine wave moves through this filter, there is a noticeable change in the sound's tone and timbre. The low-pass filter molds the sine wave, softening its edges and adding depth and richness to its sound. The result is a warm, mellow tone that is characteristic of analog synthesizers. This audio piece is a perfect example of a modular synth patch, where different modules are connected in a variety of ways to create complex sounds. This specific patch involves using two key modules: the VCO and
