The audio titled "Low-Pass Filter" is a detailed exploration of sound modulation using synthesizers. It begins with the introduction of a vibrant, raw sound, presumably generated through a synth. This sound serves as a base that undergoes a series of transformations throughout the piece, demonstrating the impact of a low-pass filter. As the audio progresses, the listener can perceive a gradual decrease in the frequency of the sound. This is the fundamental characteristic of a low-pass filter, which allows frequencies lower than a certain cutoff point to pass through while attenuating higher ones. The result is a smoother, more mellow sound that retains the original's essence but feels significantly different. Additionally, the audio emphasizes the versatility of synth filters, particularly the low-pass filter, in shaping and contouring sound. There are moments where the sound is manipulated to produce rhythmic patterns, indicating the use of a low-pass filter in a rhythmic context. T
