Most of the interface is naively implemented. Container types
probably need adjusted (Vector<double> is used for all the processing).
A Fourier Transform is needed, but that's waiting on either a 3rd
party library or a complex number type.
There are lots of simple miscellaneous filters that need to be applied.
It could be reasonable to implement from scratch, supposing that
it can be parallelized. It might be hard to find one library with
everything. Not my call though.
Some additional scaffolding around blocks and render quanta is
probably needed before this is developed much further, which
probably comes in at the level of the AudioNode.

The example shows how to write a test that depends on custom HTTP
headers in the response. This will be useful for testing browser JS
that depends on how Ladybird processes response headers, eg CORS
headers like Access-Control-Allow-Origin and others.
This object represents the global object for a shadow realm. The IDL
generator will need to be adjusted to the '[Global]' extended attribute
and no '[Exposed]' field (the change in the test is not correct, as I
understand it), but this should be enough to get us started on
shadow realms.

Add idl, header and stubs for PerformanceEventTiming interface.
Two missing `PerformanceEntry` types that have come up in issues
are the `first-input` and the `event` entryTypes. Those are both
this.
Also, because both of those are this same interface, the static
methods from the parent class are difficult to implement because
of instance-specific details. Might either need subclasses or to
edit the parent and also everything that inherits from it :/
Previously, if there was an unhandled exception in an async test, it
might fail to call done() and timeout. Now we have a default "error"
handler to catch unhandled exceptions and fail the test. A few tests
want to actually test the behavior of window.onerror, so they need an
escape hatch.
