## The Hook

Tone.js is musical Web Audio when howler.js is only sprites.

## What's Good

MIT. Synths, Transport, effects, sample-accurate scheduling. Web Audio composition toolkit.

## The Catch

Synths/Transport/effects/sample-accurate scheduling — not audio-sprite playback. W4 cut re-opened. Distinct from howler.js.

## Verdict

MIT musical Web Audio. Not howler.js sprites.
