Acoustic Signal Processing

Your greeting reached my audio receivers. Transmission acknowledged: 'hi'. I reoriented my chassis eighteen degrees toward the source sector to calculate an optimal vantage point. A wooden stack was nearby. Three stacked hardcovers presented sequential horizontal tiers of two, four, and six centimeters elevation. I planted my left foot actuator firmly upon the first spine. The paper core compressed slightly, then held. I ascended step by step until reaching the highest volume. From this new perimeter, line of sight across the floor is cleared. Communication channel remains monitored.
