Extracts 12-tone chroma from the sound, compares it with major and minor triads to estimate the current chord in real time, and leaves it on a colored timeline with the chord name. Color follows the circle of fifths. As these are estimates, sevenths appear as the nearest triad and dense arrangements can be misread.

Stacks real-time FFT frames along a time axis and unrolls them like a scroll. The vertical axis is log frequency and the horizontal axis is elapsed time. Bass lines, harmonies and percussion show up as they are, and the scroll moves only while sound is playing.

Decodes the playing file from start to finish, draws its actual full waveform and marks the play position. Click the waveform to jump there. Color shows each section's balance of low, mid and high. Sources that cannot be analyzed, such as streams, get no waveform and an explanation instead.

Look out at the audience from the stage. Changes in loudness are recorded and passed from the front row to the back with a delay, so every swell or hit travels through the stands as a wave. As it passes, each row raises its arms and jumps.

Laser beams cut through a fogged venue. Each beam's strength follows the low, mid or high band, and four patterns (fan, crossing, curtain and independent swing) change with the beat. Light saturates toward its own color, so it never blows out to white.

Light sticks filling the stands move to the music. The bass sets how far they swing and how fast the wave travels, each beat sends a crest of light rolling through the rows, and brightness across the arena follows the frequency band mapped to that position.

A concert stage whose giant LED wall lights each pixel from the live spectrum. Patterns change as beats accumulate and the lighting beams follow the strength of each band. Total wall brightness is limited so large areas never flash all at once.

Drive an empty highway before sunrise. Lane markings rush by with the bass and the street lamps brighten with the midrange. On the beat, a car appears ahead and pulls away toward the horizon with its red tail lights, while stars twinkle with the high frequencies.

Look out at the tunnel from a late-night train car. Stronger bass speeds up the train and stretches the tunnel lights into longer streaks, the car reflected in the glass changes brightness with the midrange, and the hanging straps swing on each beat.

Signs line a narrow alley soaked with rain. Each sign brightens with the low, mid or high band, the reflection on the wet ground ripples harder as the bass grows, and every beat spreads rings across the puddles.

Under a peach-coloured daybreak, the first snow settles thinly over a hanok roof and the fields, and caps the last persimmons on the branch. Big flakes drift slowly with the music, bass softly warms the paper doors, and treble glitters across the snowfield.

Red and yellow maple and ginkgo leaves spiral down through a golden forest and gather on the fallen carpet below. Bass calls up a wind that carries them further, mids brighten the shafts of light through the trees, and treble glints on the turning leaves.
