🔧 Adding Custom Effects

Every DSP module implements:

public class MyEffect : IAudioEffect
{
    public string Name      => "MyEffect";
    public bool   IsEnabled { get; set; }

    public void Process(Span<float> buffer)
    {
        // Your DSP logic here
    }

    public void Reset()
    {
        // Clear internal state
    }
}

Register it in DSPChain.CreateDefault().

⚙ Performance Architecture

• 48000 Hz internal engine
• Mono float32 processing
• 3-thread pipeline:
  • WASAPI Capture (TimeCritical)
  • DSP Thread (Highest)
  • WASAPI Output
• Zero allocations in audio hot path
• Lock-free ring buffer
• ~12–20ms latency (Shared mode)
• Optional exclusive mode for lower latency

---

📦 Building Installer

Install Inno Setup:
https://jrsoftware.org/isinfo.php

Then:

dotnet publish VybeShift.UI -c Release -r win-x64 --self-contained
iscc installer\setup.iss

This generates:

VybeShift_Setup_vX.X.X.exe

---

🔒 Privacy

• No telemetry
• No data collection
• No cloud processing
• 100% local audio engine
