Peace Preset Generator

AI-powered EQ preset generator for Peace Equalizer (Equalizer APO extension). Uses device-specific profiles and audio engineering principles to generate optimized presets for any audio device and music genre.

🎧 What is This?

An AI-powered preset generator that creates genre-optimized EQ profiles for Peace Equalizer. Unlike generic device correction profiles, this tool generates ready-to-import presets that combine:

• Device-specific compensation - Corrects your headphones/speakers frequency response weaknesses
• Genre-specific optimization - Different curves for Metal, Trance, Classical, etc.
• Audio engineering expertise - Professional EQ principles applied automatically

What Makes This Different?

✅ This project generates:

• Genre-tailored presets (same device, different sound for different music)
• Ready-to-import .peace files (no manual configuration)
• AI-assisted creation at scale (request any genre + device combination)
• Detailed engineering rationale for each preset

❌ This is NOT:

• A manual device correction database
• A one-size-fits-all EQ profile
• A replacement for researching your device's characteristics
• Audio driver software or hardware modification

Think of it as: A smart preset factory that understands both your audio device's technical limitations AND what your favorite music genres need to shine.

🔍 Real-World Example

Scenario: You own Sennheiser HD 4.40 BT headphones and a JBL Flip 6 speaker. You listen to both Heavy Metal and Classical music.

Generic device profile approach: One EQ curve that "corrects" your device. Sounds decent for everything, perfect for nothing.

This generator's approach:

• Heavy Metal - HD 4.40 BT.peace - Aggressive headphone curve (closed-back, sealed bass)
• Heavy Metal - JBL Flip 6.peace - Controlled speaker curve (room acoustics, distance-aware)
• Classical - HD 4.40 BT.peace - Natural headphone balance
• Classical - JBL Flip 6.peace - Natural speaker balance (different from headphone version)

Same genres, different devices, each preset optimized for the specific combination.

🎛️ How It Works

1. Device Profiles

Each supported device has a detailed profile documenting:

• Native frequency response characteristics
• Known strengths and weaknesses
• Compensation strategies
• Device type (headphone/speaker/soundbar)
• Connection type (Bluetooth/wired/optical)
• Use case considerations (listening distance, room placement)

See device_profiles/ for examples.

2. Genre Analysis

The generator understands what different music genres need:

• Electronic/Trance: Deep sub-bass, scooped mids, sparkly highs
• Metal: Punchy bass, clear mids (no mud), aggressive treble
• Pop/R&B: Balanced with vocal presence
• Classical: Natural, minimal correction

3. AI-Assisted Generation

Using audio engineering principles, the generator:

1. Reads the device profile
2. Analyzes genre requirements
3. Accounts for device type and use case (headphones vs speakers)
4. Calculates optimal EQ compensation
5. Generates the .peace preset file

🔧 Generating New Presets

Want a preset for a different genre or your specific audio device?

Option 1: Request via Issue

Open a GitHub Issue with:

• Your device model (headphone, speaker, soundbar)
• Desired music genre
• Any specific preferences

Option 2: Use Claude Code (AI-Assisted)

If you have access to Claude Code:

1. Add your request to config/PRESETS_TO_CREATE.md:

   Lo-Fi Hip-Hop @ Sennheiser HD 4.40 BT
   Progressive House @ JBL Flip 6
   Classical @ Default
   

2. Run the generator workflow (see CLAUDE.md)

3. New presets appear in output/ with engineering notes

🎯 Supported Devices

Headphones

• ✅ Sennheiser HD 4.40 BT - Bluetooth, V-shaped signature
• ✅ JBL Tune 520BT - Bluetooth, bass-heavy consumer tuning

Speakers

• ✅ JBL Flip 6 - Portable Bluetooth speaker, 2.0 stereo

📊 Preset Format

Each .peace file uses 13 frequency bands:

Frequency	Purpose
10-21 Hz	Sub-bass (felt impact)
42-83 Hz	Bass fundamentals
166-333 Hz	Upper bass / muddiness zone
577 Hz	Lower mids (clarity)
1-2 kHz	Midrange (vocal presence)
4-8 kHz	Upper mids (definition)
16-20 kHz	Treble (air and sparkle)

Gain adjustments: -12 dB to +12 dB
Quality factor: 0.7 (standard)

🤝 Contributing

Contributions welcome! Here's how:

Add Your Device Profile

1. Fork this repository
2. Research your device's frequency response (RTINGS, Crinacle, ASR, manufacturer specs)
3. Create device_profiles/[category]/[Your Model].md using existing profiles as template
4. Add to CONFIG.md available profiles list
5. Submit a pull request

Share Your Preset

If you've manually tuned a great preset:

1. Add it to output/[Genre] - [Device].peace
2. Document in config/CREATED_PRESETS.md with reasoning
3. Submit a pull request

🎯 Core Philosophy

Genre + Device = Optimized Sound

This generator solves a specific problem: Your audio device sounds different depending on what you're listening to.

A heavy metal track needs punchy, aggressive mids and controlled bass. A vocal trance track needs deep sub-bass and sparkling highs. Classical music needs natural balance with minimal coloration.

Generic device profiles can't do this. They correct the device but ignore the music and use case.

This tool creates targeted presets that answer: "How should this specific device (headphones/speakers) be EQ'd for this specific genre?"

What You Get

Each generated preset includes:

• Device analysis - What frequencies need correction
• Genre requirements - What the music style demands
• Use case considerations - Room acoustics, listening distance (for speakers)
• Engineering rationale - Why each frequency band is adjusted
• Ready-to-use file - Just import and listen

What You Need to Provide

• Your exact device model (or add it to the profiles)
• The music genre you want optimized
• Trust in audio engineering principles (or tweak to taste)

🔬 Technical Details

Why These Specific Frequencies?

The 13-band configuration covers the entire audible spectrum with focus on:

• Sub-bass extension (10-21 Hz) - Physical impact
• Bass control (42-166 Hz) - Warmth without boom
• Mid clarity (333-577 Hz) - Reducing muddiness
• Vocal presence (1-2 kHz) - Forward vs atmospheric
• Definition (4-8 kHz) - Clarity without sibilance
• Air (16-20 kHz) - Sparkle and space

Bluetooth Compensation

Bluetooth presets account for:

• High-frequency roll-off (codec limitations)
• Dynamic compression
• Latency (not audible in EQ but documented)

⚠️ Important Notes

• Start conservative: Try presets at 80% volume first
• Room acoustics matter for speakers: Speaker presets assume typical room placement; adjust if near walls
• Headphones vs Speakers: Don't use headphone presets on speakers (or vice versa) - each is optimized differently
• Source quality: High-quality audio files benefit most from EQ
• Personal preference: Feel free to adjust +/- 2dB to taste
• Hearing safety: Avoid excessive bass boost at high volumes
• Genre-specific: A "Heavy Metal" preset will sound wrong on classical music (that's the point!)
• Not a fix-all: Can't fix broken drivers or poor source material

💡 Use Cases

Perfect for:

• Music enthusiasts who listen to multiple genres
• Audiophiles wanting optimized sound per music style
• Users tired of manually tweaking EQ for different playlists
• Anyone wanting professional-grade presets without the learning curve

Not ideal for:

• All-purpose "set and forget" EQ (use generic device profiles instead)
• Professional mixing/mastering (use flat reference monitoring)
• Fixing hardware defects (get better equipment)
• Live audio processing (latency considerations)
• Multi-channel surround systems (not yet supported - see ROADMAP.md)
