SpigenAudioCTRL

An unofficial Windows desktop companion app for the Spigen SA-HP P10 over-ear headphones. Built natively with C#, WPF, and WinRT Bluetooth LE GATT — no Electron, no middleware.

Features

Noise Control

• ANC modes: Deep, Adaptive, Commuting, Anti-Wind, Transparency, Off
• Low-latency Gaming Mode toggle

Equalizer & Audiophile Audio Engine

• 10-Band Parametric Hardware DSP EQ: Full control over frequency (20 Hz – 20 kHz), gain (±8 dB), and Q-factor bandwidth ($Q=0.2$ to $5.0$) written directly to headphone memory
• Dynamic Anti-Clipping Pre-Amp: Automatic pre-attenuation calculation ($\min(0\text{ dB}, -\max(\text{Gain}))$) ensuring 100% distortion-free playback with maximum dynamic headroom
• Interactive Logarithmic Studio Canvas: Drag vertically for gain, drag horizontally to sweep center frequency, scroll mouse wheel to widen/narrow Q-factor bandwidth
• Selected Band Parametric Inspector: Fine-tune frequency, gain, and Q-factor sliders with real-time composite filter response curve
• Calibrated Audiophile Presets:
  • P10 Audiophile Master (Recommended) — Custom-engineered for P10 hardware: anti-mud cut, pinna gain rise, sibilance taming
  • P10 Dynamic V-Shape Rumble — Sub-bass punch and sparkling air for EDM/Hip-Hop
  • Harman Over-Ear Target 2018 (Benchmark)
  • Diffuse Field Studio Reference
  • Vocal Clarity & Anti-Sibilance (-3.5dB surgical notch at 7.5kHz)
  • Deep Sub-Bass Clean Rumble (45Hz lift with anti-mud cut)
  • Warm Audiophile Soundstage
  • Gaming Spatial & Footstep Enhancement
  • Default Flat (Reference 0dB)
• Harman Target Reference Overlay: Toggleable visual target curve on the canvas
• Custom Preset Storage: Save, recall, and reset custom parametric tunings

Button Remapping

• Remap Multi-Function Button: Single, Double, Triple Click
• Remap Volume keys: Single Click, Long Press
• Available actions: Play/Pause, Next/Prev Track, Volume, Voice Assistant, Gaming Mode, ANC Cycle
• Changes are written directly to onboard headphone memory

Connectivity

Build

Standalone executable:

build.bat

Or manually:

dotnet publish SpigenAudioCTRL.csproj -c Release -r win-x64 --self-contained true -p:PublishSingleFile=true -o dist/

Output: dist\SpigenAudioCTRL.exe (~78 MB, self-contained, no runtime installation required)

Run from source:

dotnet run

Architecture

File	Role
BluetoothService.cs	BLE GATT connection, scanning, characteristic management
RcspProtocol.cs	RCSP packet encoding (ANC, EQ, Gaming Mode, Key Mapping, hardware queries)
MainWindow.xaml.cs	UI state, EQ canvas rendering, button remapping grid
App.xaml.cs	Global unhandled exception handlers

---

Protocol

The SA-HP P10 communicates over BLE GATT using a proprietary RCSP framing:

FE DC BA [flags] [opcode] [len_hi] [len_lo] [sn] [payload...] EF

• Write characteristic: UUID contains ae01 or 0001
• Notify characteristic: UUID contains ae02 or 0002
• Battery: Standard BLE Battery Service — UUID 0x180F, Characteristic 0x2A19
