187AUDIO skill

187AUDIO — Audio-reactive 3D geometry.

Connects Web Audio to Three.js so meshes react to music or mic input, with clear permission and safety notes.

Audio lab

5 live audio systems

The two 187AUDIO patterns wired to the real Web Audio API — plus a few extra tricks for the cool factor: a playable theremin, pentatonic pluck pads, and a spectrum-bloom arpeggiator. Everything is a soft sine chord or pluck (no harsh tones), needs no audio file, and tears its audio graph down on stop. Press Start / Play, or tap the pads.

Audio-Reactive Visualizer

/187colorwaveaudio

A real WebAudio AnalyserNode feeds a live waveform to the glowing curve; press Start to sound a soft chord pad.

Click

Spectrum Bloom Arp

★ bonus

A pentatonic arpeggio of plucks runs through a real AnalyserNode; each note blooms a glowing frequency bar.

Drag
press & glide

Theremin

★ bonus

Press and glide — X bends the pitch, Y the volume, with a 5.5Hz vibrato and a low-pass for warmth.

Click

Pentatonic Pluck Pads

★ bonus

Tap any pad for a soft two-oscillator pluck with a fast decay envelope — pentatonic, so it never clashes.

Custom Audio Player

/187howler

A Howler-style player — play/scrub/volume UI wired to a soft WebAudio chord pad, so it needs no audio file.
