Mature woman's very fast heartbeat Her beautiful and powerful heart never stopped beating throughout her long performance. It reaches its peak around the second half of the video and remains at extraordinarily high levels. This mature woman is stunning in her passionate speech. Her heartbeat fully conveys the emotions that filled her. Audio Track 1 is processed with high-frequency enhancement. I tried to find and highlight that distinct βclickβ from her hard-working heart valves. Audio Track 2 is more classic. It emphasizes the pulse in the lower frequency range. Which one is better?
