Sorting Machine for Letters 4

The audio begins with the soft hum of a machine, an industrial-grade device designed for a specific purpose: sorting letters. The setting is indoors, a large room echoing with the rhythmic noise of automated efficiency. There's a steady, systematic sound, like a heartbeat at work. This is the sound of the sorting machine, processing a steady stream of envelopes. The machine's mechanisms whir into action, clattering slightly as it sorts through the letters. There are intermittent clicks and clacks, the sound of paper against metal, as each letter finds its designated slot. Occasionally, the machine's tempo changes, adjusting to different sizes or weights of the envelopes. The machine's rhythm is punctuated by the soft thud of each sorted letter landing in its respective bin. The overall ambiance of the audio is one of synchronized, industrial harmony, a testament to human ingenuity in the world of automation.
