SLOWSHADE – Instant Slowdown & Tone Transformation App
SlowShade is a powerful standalone audio tool for creative sound design and detailed analysis. It allows you to:
· Adjust Playback Speed: Slow down or speed up audio with pitch following speed.
· Drive: Add rich, analogue warmth and gentle push to your sound with soft saturation.
· Shade: Sculpt your tone by smoothly filtering out harsh high frequencies, creating a darker or brighter feel.
· Width: Expand or narrow your stereo soundscape, from focused mono to super-wide.
Beyond these sonic transformations, SlowShade features high-resolution visual feedback including a real-time dual-layer spectrum analyzer (Dry/Wet FFT), precise LR Peak Meters, and a Stereo Correlation meter for phase monitoring. With easy drag-and-drop loading and WAV export, it is designed for fast, deep exploration and refinement of your audio.
