audiocontext-defined AudioContext is exposed on the global — the surface for the new renderSizeHint option. script
renderquantumsize-on-prototype BaseAudioContext.prototype exposes a renderQuantumSize attribute — the readable counterpart to renderSizeHint. spec ↗ script
default-quantum-is-128 A freshly-constructed AudioContext with no options reports renderQuantumSize === 128 frames per spec. spec ↗ script
renderSizeHint-accepts-integer Passing renderSizeHint as an integer is permitted by the AudioContextOptions dictionary; constructor must not throw for a small valid hint. spec ↗ script
renderSizeHint-accepts-default-keyword renderSizeHint accepts the 'default' enumeration value. spec ↗ script
renderSizeHint-accepts-hardware-keyword renderSizeHint accepts the 'hardware' enumeration value — UA picks a render quantum optimised for the device. spec ↗ script
