SlowShade

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.

"Fully coded DSP & GUI — no images, no SVGs, no skins. Pure signal."
