The audio begins with the steady hum of a belt grinder in operation. It's a distinct, mechanical sound, characterized by a consistent, smooth roar. The rhythmic grinding and whirling noise creates a vivid picture of a workshop scene. This noise is occasionally punctuated by the sound of metal being ground, which adds a sharper, high-pitched whine to the overall audio mix. Following this, the sound changes to that of a thickness planer. The noise is loud, powerful, and continuous, reminiscent of heavy-duty woodworking. The planer's motor emits a low, steady drone, overlaid with the higher-pitched, rapid-fire noise of the wood being fed through the machine and shaved down. There's the occasional sound of wood chips being expelled, adding a soft, almost rustling undertone to the audio. Throughout the audio, there's a strong sense of activity and purpose, painting a vivid picture of a bustling workspace with these two machines - the belt grinder and the thickness plan
