1.10 (02-09-2026)

• Fix: Disable LED on startup causing some issue when cold start
• New: MIC Frequency Balance option.
  Most common speakers output more low frequencies than high frequencies, which can cause the visualizer to appear biased toward the left side of the screen.
  This setting lets you control how much mid-to-high frequency data is taken into account when rendering the display:
  • Normal (default) – Tuned for typical speakers, prioritizing the most commonly emitted frequencies.
  • Large – Takes more mid-to-high frequencies into account for a more centered visual.
  • XL – Takes the full frequency range into account, matching the behavior from previous versions.
