Disable Features One by One

1. Note Current CPU Usage

   Open Task Manager and note Jyv Desktop CPU percentage

2. Disable Transcription

   Settings → Features → Transcription → Toggle OFF

   Wait 5 seconds, check if CPU dropped. If yes, transcription was the culprit. Keep disabled or reduce quality settings.

3. Disable Voice Enhancement

   Settings → Audio → Voice Enhancement → Toggle OFF

   Check CPU drop. If large drop, voice enhancement was using CPU.

4. Disable Noise Suppression

   Settings → Audio → Noise Suppression → Toggle OFF

   Check CPU drop again.

5. Disable Audio Routing

   Settings → Audio → Advanced Features → Disable routing

   If using complex routing, this might reduce CPU.

6. Re-enable Features Selectively

   Once you find the culprit:

   • Re-enable only needed features
   • Test each configuration
   • Find acceptable balance between features and performance

CPU Usage by Feature

{
  "cpuUsageEstimates": {
    "baseline": {
      "idling": "0-2%",
      "audioRouting": "2-5%"
    },
    "noiseSuppression": {
      "light": "5-8%",
      "balanced": "8-12%",
      "aggressive": "12-18%"
    },
    "voiceEnhancement": {
      "natural": "8-12%",
      "professional": "12-18%",
      "broadcast": "18-25%"
    },
    "transcription": {
      "fast": "15-20%",
      "balanced": "20-30%",
      "accurate": "30-40%"
    }
  }
}

Transcription Optimization

Transcription is the most CPU-intensive feature:

• Disable if not needed: Only enable when actually transcribing meetings
• Use Fast mode: Settings → Transcription → Quality: Fast (instead of Accurate)
• Disable speaker detection: Identify Speakers OFF (saves 5% CPU)
• Single language: Auto-detect OFF if you speak one language (saves 3% CPU)

Voice Enhancement Optimization

• Use Natural mode: Less CPU than Professional/Broadcast
• Disable if not needed: Only enable for voice calls or streaming
• Reduce EQ bands: Less EQ = less CPU
• Disable advanced features: De-esser, breath reduction consume CPU

Noise Suppression Optimization

• Use Light mode: Instead of Aggressive (5-8% vs 12-18% CPU)
• Disable profile learning: Settings → Noise Suppression → Profile Learning OFF
• Only for voice input: Disable when just listening to music/games

Audio Buffer Optimization

Larger buffers are more CPU-efficient:

• Settings → Advanced → Audio Buffer
• Increase to 512 or 1024 samples
• Larger buffers = slightly higher latency but less CPU
• For non-real-time use (transcription), 1024 is fine
• For gaming, keep at 256-512 for low latency

Sample Rate Optimization

Sample rate affects CPU usage:

• Settings → Audio → Sample Rate
• 44.1kHz: Lowest CPU (music quality)
• 48kHz: Standard, good CPU balance (recommended)
• 96kHz: Higher CPU, usually not needed for voice
• Reduce from 96kHz to 48kHz if needed

Real-Time Priority

Jyv Desktop needs consistent CPU time. Disable other CPU-intensive tasks:

• Close browser tabs: Especially video streaming
• Pause video calls: If not needed
• Disable automatic updates: Pause Windows updates
• Disable antivirus scanning: Schedule for off-hours
• Close resource-heavy apps: Video editing, 3D rendering, etc.

Background Process Cleanup

Other applications might be consuming CPU:

1. Open Task Manager

   Press Ctrl + Shift + Esc

2. Sort by CPU Usage

   Click CPU column header. Identify high-CPU processes:

   • Chrome, Firefox, Edge (browsers)
   • OneDrive, Dropbox, Google Drive (cloud sync)
   • Windows Search indexing
   • Antivirus/malware scans
   • GPU driver software (NVIDIA, AMD control panel)

3. Disable Unnecessary Services

   Services → Disable non-essential background services

   • Windows Search (if you don't use it)
   • Bluetooth (if not using wireless)
   • Background apps (Settings → Apps → Startup)

4. Check Disk Usage

   High disk activity can cause CPU spikes. Check:

   • Task Manager → Disk tab
   • If at 100%, pause heavy disk operations

Driver Updates

Outdated audio drivers can be inefficient:

• Device Manager → Sound, video and game controllers
• Right-click audio device → Update driver
• Choose "Search automatically for drivers"
• Restart computer after update

Power Settings

Windows power plan affects CPU behavior:

• Settings → System → Power & battery
• Set to "Balanced" or "High performance" (not Power Saver)
• Power Saver throttles CPU, causing stuttering
• Disable sleep mode while using Jyv Desktop

CPU Specifications Matter

Older/Slower CPUs:

• Disable transcription
• Use Light noise suppression only
• Disable voice enhancement
• Use basic audio routing only

Laptop vs Desktop

Laptops:

• Thermal throttling kicks in faster than desktops
• Keep laptop cool (don't block vents)
• Use on hard surface, not bed/couch
• Consider external cooling pad if frequently hot

Desktops:

• Ensure good case airflow
• Clean dust filters monthly
• Consider CPU cooler upgrade if thermal throttling

When to Upgrade Hardware

If after all optimizations you still can't use needed features, consider:

• CPU Upgrade: Move to newer, faster processor
• Laptop Replacement: Newer laptops with efficient CPUs (M1/M2/M3)
• RAM Upgrade: More RAM reduces disk swapping overhead
• SSD: Solid-state drive is much faster than spinning disk
