Measured entry

ruixen-live-waveform

inputunclassifiedmotion on file

A client-side React waveform panel shipped as a shadcn registry component. It draws idle, processing, or microphone-driven bars on a canvas, requests audio through browser media APIs, and includes an optional stop button. It depends on Lucide, a cn utility backed by clsx and tailwind-merge, Tailwind theme classes, and ResizeObserver.

Verdict

A focused, convincing voice-state visual for shadcn-based apps, with useful tuning props and clean microphone teardown. It needs a shadcn-style setup to build and mount, and teams should fix the narrow-layout overflow and contrast before shipping it.

Use it if

  • You need a compact voice-input status surface with distinct idle, processing, and listening states.
  • Your app already uses shadcn conventions and can grant microphone access in a secure browser context.
  • You want a configurable canvas waveform without adopting a charting or audio visualization library.

Skip it if

  • The component must fit narrow layouts without additional responsive work, since the verified mobile demo overflows.
  • You need accessible colors out of the box, since the tested presentation has a serious contrast issue.
  • Your product cannot request microphone permission or must support environments without browser media and canvas APIs.
  • You need recording, playback, elapsed time, or audio persistence rather than a visual state indicator.

In a non-shadcn project, add Lucide React, clsx, and tailwind-merge; provide a compatible cn helper; map the Tailwind border, card, foreground, and background theme classes; and keep the component client-side where canvas, ResizeObserver, AudioContext, and mediaDevices are available.
