AI-Powered EQ

Jyv Desktop analyzes your voice in real-time and applies intelligent equalization:

• High-Pass Filter: Remove rumble below 80 Hz
• Low-Mid Cut: Reduce muddiness (200-400 Hz)
• Presence Boost: Enhance clarity (2-5 kHz)
• Air Band: Add brightness and crispness (8-12 kHz)
• Adaptive Processing: Adjusts to your voice characteristics

Smart Compression

Automatic compression ensures your voice stays at a consistent volume:

{
  "compression": {
    "enabled": true,
    "ratio": 3.5,              // 3.5:1 compression ratio
    "threshold": -18,          // dB threshold
    "attack": 5,               // ms attack time
    "release": 150,            // ms release time
    "makeupGain": 3,           // dB gain compensation
    "kneeWidth": 6             // Soft knee for natural sound
  }
}

De-esser

Reduces harsh sibilance (S, SH, CH sounds) without affecting clarity:

{
  "deEsser": {
    "enabled": true,
    "frequency": 7000,         // Center frequency for S sounds
    "bandwidth": 2000,         // Hz range to process
    "threshold": -25,          // dB threshold
    "ratio": 4,                // Reduction ratio
    "listenMode": false        // Enable to hear isolated S sounds
  }
}

Room Tone Removal

Reduces reverb and echo caused by your room acoustics:

• Reverb Suppression: Reduce room reflections
• Echo Cancellation: Remove delayed reflections
• Proximity Effect: Add warmth for close-mic sound
• Space Simulation: Optional - add professional studio ambience

Breath Reduction

Intelligently reduces breathing sounds while preserving natural speech:

{
  "breathReduction": {
    "enabled": true,
    "strength": 0.6,           // 0-1, strength of reduction
    "threshold": -40,          // dB threshold for breath detection
    "preserveNatural": true,   // Keep some breath for realism
    "aggressive": false        // Enable for maximum removal
  }
}

Voice Sounds Robotic or Unnatural

Cause: Too much processing or wrong settings

Solution:

• Reduce EQ strength to 40-60%
• Lower compression ratio (try 2:1 or 3:1)
• Disable or reduce breath reduction
• Switch from Broadcast mode to Professional or Natural
• Ensure only Jyv Desktop is processing (disable app noise suppression)

Voice Sounds Thin or Lacks Warmth

Solution:

• Increase Warmth setting (+3 to +6 dB)
• Boost low-mids (200-400 Hz) in custom EQ
• Enable Proximity Effect simulation
• Ensure high-pass filter isn't too aggressive (<100 Hz)

S Sounds Are Still Too Harsh

Solution:

• Increase de-esser strength to 70-80%
• Lower de-esser threshold (-30 dB or lower)
• Enable "Listen Mode" to hear isolated sibilance
• Adjust de-esser frequency (try 6000-8000 Hz range)
• Ensure de-esser comes after compression in signal chain

Volume Jumps Around Too Much

Solution:

• Increase compression ratio (4:1 or 5:1)
• Lower compression threshold (-20 dB or lower)
• Reduce attack time (3-5 ms for fast response)
• Enable limiter to catch peaks
• Consider using Broadcast mode for maximum consistency

Processing Adds Noticeable Latency

Solution:

• Reduce buffer size in audio settings (try 256 or 128 samples)
• Enable GPU Acceleration for voice processing
• Switch to Performance Mode (slightly lower quality, faster)
• Disable breath reduction (most CPU-intensive feature)
• Close other CPU-intensive applications
