Bass Frequency Sweep from 20 to 70Hz

The audio titled "Bass Frequency Sweep from 20 to 70Hz" is an auditory exploration that delves into the lower registers of sound, ideal for testing or showcasing the capabilities of a subwoofer. The audio begins with a low, deep rumble at 20Hz, the very edge of human hearing ability, often more felt than heard, often associated with the sub-bass range. As the audio progresses, the bass frequency gradually increases, creating a sweeping effect that feels akin to an auditory wave. This 'sweep' travels slowly and steadily upwards, reaching 70Hz. This range of frequencies is characteristic of the lower end of the bass spectrum, providing a resonant and palpable sensation, often physically felt when played through high-quality audio equipment. The sound is synthesized, created using modulation techniques to generate a pure sine wave. This ensures a smooth, clean sound devoid of harmonics, which allows the listener to focus entirely on the bass frequencies. The result is
