Before Change

plt.plot(times, rms)
plt.axhline(0.02, color="r", alpha=0.5)
plt.xlabel("Time")
plt.ylabel("RMS")
plt.axis("tight")
plt.tight_layout()

// The red line at 0.02 indicates a reasonable threshold for silence detection.

After Change

plt.figure(figsize=(12, 6))
fig, ax = plt.subplots(nrows=2, sharex=True)
librosa.display.specshow(librosa.amplitude_to_db(S_full, ref=np.max),
                         y_axis="log", x_axis="time", sr=sr, ax=ax[0])
ax[0].label_outer()
ax[1].step(times, p>=0.5, label="Non-silent")
