Spectral formant engine
Shifts the spectral envelope ±1200 ct without changing pitch — the spectral approach used by Color Transfer-style shifters.

Features
What it does
AkiTilt grew out of how producers in the Botanica scene shape voices and textures: automating formant on guitar loops, morphing voices into new characters, tuning noise into air. A JUCE 8 plugin styled with the Mint Fresh theme of the Aki Design System.
Auto Formant
Tracks input pitch and shifts formants with it; the knob becomes a fine offset for expressive rides.
Companion controls
Pitch (±12 st granular), tilt EQ (±12 dB), mid/side width and an Air noise bed in one panel.
XY pad + spectrum
Formant × pitch XY pad with live spectrum display, plus 9 factory presets and plain-XML user presets.
A/B compare
Instant A/B compare, in/out level meters and full host automation with latency reporting.
Tunable analysis
Bands 0–32 and FFT size 128–4096 — trade latency for formant smoothness to fit the material.

项目简介
AkiTilt 源自 Botanica 场景制作人对人声与质感的处理方式：在吉他循环上自动化共振峰、把人声变形为新的角色、把噪声调校成空气感。基于 JUCE 8 构建，采用 Aki 设计系统的 Mint Fresh 主题。
频谱共振峰引擎
在不改变音高的前提下移动频谱包络 ±1200 ct，采用 Color Transfer 一类工具的频谱方案。
自动共振峰
跟随输入音高同步移动共振峰，旋钮变为微调偏移，方便自动化演奏。
配套控制
Pitch（±12 st 粒度移调）、Tilt EQ（±12 dB）、mid/side 宽度与 Air 噪声床，一屏齐备。
XY 板 + 频谱
共振峰 × 音高 XY 控制板带实时频谱，内置 9 个出厂预设与纯 XML 用户预设。
A/B 对比
A/B 即时对比、输入输出电平表与完整宿主自动化，含延迟上报。
可调分析
Bands 0–32 与 FFT 128–4096，在延迟与共振峰平滑度之间按素材取舍。
