## What is DeciMate SPL?

DeciMate SPL helps you monitor sound levels during rehearsals, DJ sets, small events, venue checks, and live-sound work. It turns your iPhone into a practical SPL monitoring
  companion with a clean real-time meter, calibration tools, threshold alerts, session history, export options, and expressive visual feedback that makes level changes easy to
  understand at a glance.

  Use DeciMate SPL to keep an eye on loudness trends, spot peaks, document sessions, and share live readings across your local network for dashboards and creative workflows.

  Features:

  - Live approximate SPL monitoring
  - Clear circular input meter with threshold-based visual feedback
  - Manual calibration offset and quick “Match Reference” calibration
  - Adjustable warning, critical, and peak thresholds
  - Threshold presets for common monitoring situations
  - Fast and slow response modes
  - Session history graph
  - Detailed session export with live-monitoring values
  - Companion animation with fullscreen focus mode
  - Screen-awake fullscreen monitoring for visual use during sessions
  - DeciMate Live Link for local network JSON streaming
  - Optional OSC streaming for dashboards, tools, and live-production workflows

  Important: DeciMate SPL uses the device microphone for practical monitoring. It is not a certified Class 1 or Class 2 sound level meter and should not be used as the sole tool
  for legal, workplace-safety, or compliance measurements.
