SoundShader turns sound into moving light. Each band of the music, from the deepest bass to the brightest cymbal, drives its own ribbons of color, so a quiet ballad and a dense electronic track, combined with a variety of visual presets, create wildly different looks. Every feature in SoundShader is totally free. LISTEN TO ANYTHING • Microphone: the visuals are totally live, following what your device hears, as it happens. • Audio files: open a song from Files and the visuals follow it exactly, with a 10-band equalizer to shape how it sounds and looks. • Apple Music: play a song from your library. On iPhone and iPad, it plays through the speaker while SoundShader listens through the microphone. MAKE IT YOURS • Eight built-in looks: Rainbow, Aurora, Violet, Flame, Moss, Embers, Party and Shadow. Save your own as presets. • Color: hue, saturation, brightness, and where the warm colors hand over to the cool ones. • Motion: speed, density and size, each of which can follow the music by itself with Auto Speed, Auto Density and Auto Size. • A flowing backdrop and a live waveform. BUILT FOR GREAT DISPLAYS • Extended Dynamic Range lets the brightest light go past white on HDR displays. • Runs up to your display's full refresh rate, including 120 hz ProMotion. • Performance Mode for less power usage and higher frame rates on older devices. PRIVATE BY DESIGN No account, no ads, no tracking. Everything SoundShader hears is analyzed on your device and never leaves it.
