Clubshot Training Timer

1. Acoustic Shot Detection

• Real-Time Detection: DSP algorithm detects live shots or dry-fire clicks and stops timing at the final shot.
• Buzzer Blanking: Start signal chime is mathematically filtered to prevent false triggers.
• Level Filter: Adaptive damping prevents echo and muzzle gas reflections from double-counting.
• Configurable Delay: Adjustable random delay for standardized preparation intervals.

2. BDS & DSB Sporting Codes

Pre-configured rules for official disciplines:

• BDS Speed Shooting: Dedicated time limits and scoring for pistol, rifle, and shotgun.
• BDS Time Series & Skill: Multi-stage flow across three series including mandatory reload periods.
• DSB 2.53 (9mm Pistol): Precision and duel stages with exact timing sequences.
• Freestyle Mode: Open interval training with custom par times.

3. Split-Time Cadence Analysis

• Measures intermediate split times relative to the immediately preceding shot.
• Calculates average split times per stage to evaluate cadence consistency.
• Audio Envelope: Visual amplitude graph over the time axis.
• Threshold Adjustment: Post-session dB threshold tuning to re-calculate detections.

4. Score Calculator & Input Modes

Three methods to record scores:

• Single-Shot Scoring: Record individual ring values (1–10, inner ten) via numeric keypad.
• Total Score: Direct entry of aggregate score for a stage.
• Deferred Scoring: Shoot consecutive stages and enter combined results afterward.

5. Offline-First Architecture

• 100% Local: Operates entirely without internet connection. All data remains on the device.
• No Raw Audio Retention: Only compressed volume envelopes (RMS) are saved. Conversations and ambient audio are never recorded.

6. Management & Profiles

• Shooter Profile: Store name, club affiliation, and personal timer presets.
• Session History: Archive, review, and export completed sessions.
• Dark Theme: System-wide light/dark styling for optimal visibility on shooting ranges.
