Aevatar — A Lightweight PNG-Tuber

Windows / Linux  

As seen on streams like 

• B1scu2T (Twitch)
• KhoraPR (Twitch)
• RudeNoodler (Twitch)

Features

Audio-reactive avatar

• Three-tier state system: idle, talking, and (optional) screaming
• Tunable threshold, smoothing, and hold timing — all live-adjustable while you talk
• Real-time mic level meter
• Optional crossfade transitions

Layered, animated artwork

• Stack layers as you want (body, eyes, mouth, hair, accessories...)
• Each layer can have separate sprites for idle, talk, and scream states
• Full APNG support — animated layers play at their original frame timing (blinking eyes, looping accessories, etc.)
• Per-layer position and scale controls for pixel-perfect alignment

Built for streaming

• True window transparency — no chroma keying needed, just window-capture in OBS
• Chroma key — green/magenta toggle (F2) if your capture method needs it
• Profile system — save multiple avatar configs and quick-switch with F4-F9 (Global hotkeys on certain systems)
• Drag-and-drop any PNG/APNG onto the window or directly onto a slot button
• Mic device selector — pick exactly which input drives the avatar

No-friction setup

• All assets and configs live in a portable data/ folder — back it up, move it, share it
• Auto-saves every change
• Native file dialogs on every platform
• Works with completely transparent backgrounds for clean OBS captures
• Lightweight: ~2-3% CPU on a modern machine

Requirements

• Windows 10+, Linux (X11)
• A microphone
• That's it

What it isn't

• Not a Live2D or 3D rig — this is for static and frame-animated PNG avatars only
• Not a webcam tracker — audio drives everything
• No subscriptions, no telemetry, no online dependencies

Controls

• Tab — open the editor panel
• F1 — toggle HUD
• F2 — cycle background (Dark / Green / Magenta)
• F3 — help
• F4-F9 — quick-switch profiles (global)
