WolfEQ 0.2.0 beta is here.
A modern Windows PEQ workspace for FiiO K13 R2R and experimental FiiO / Snowsky device support.
WolfEQ is a desktop app for people who want a cleaner way to tune PEQ on supported FiiO and Snowsky devices. Instead of juggling device menus, preset files, and separate graph tools, WolfEQ brings the core workflow into one Windows app: choose a slot, shape the curve, preview the response, save, and keep your profiles organized.
The FiiO K13 R2R is the main tested device. WolfEQ 0.2.0 beta also adds early experimental profiles for KA15, KA17, JA11, Snowsky Melody, and Snowsky Retro Nano.

WolfEQ 0.2.0 beta adds:
- 🎧 Experimental device profiles for FiiO KA15, FiiO KA17, FiiO JA11, Snowsky Melody, and Snowsky Retro Nano.
- 📈 A cleaner PEQ graph with hover readouts, better band handles, and a more standard response feel.
- 🎛️ A redesigned tuning workspace with compact band rows and a right-side preset/profile panel.
- 📚 A better library tab with online profile search, import/export tools, and cleaner device-slot names.
- 💾 Improved K13 read-on-boot, slot switching, save confirmation, and post-save reload behavior.
- 🎚️ Edits PEQ gain, frequency, Q, filter type, and global preamp.
- 📈 Shows a live response preview while you shape a preset.
- 💾 Reads, writes, and refreshes K13 USER slots over USB.
- 📚 Saves, imports, exports, duplicates, favorites, and deletes local presets.
- 🔎 Searches online AutoEq profiles so you can start from known headphone correction curves.
- 🧰 Imports and exports WolfEQ JSON, Equalizer APO text, and FiiO XML.
⚠️ Flags clipping risk and helps apply safer headroom before writing to hardware.

This is beta software, and the newest device profiles are intentionally marked experimental. If you try KA15, KA17, JA11, Snowsky Melody, or Snowsky Retro Nano, please treat it like early support and report what works, what fails, and what the device shows when switching or saving.
Still being explored:
- front-panel LCD text
- volume control
- EQ on/off switching
- NOS / OS / SAM mode switching
- optical and Bluetooth input switching
Please open an issue if something breaks or feels strange. Include your Windows version, device model, USB mode, and the exact preset/slot action you were doing.
