Audio-ISSUE-48 (AudioBufferSimpl): AudioBuffer simplification [Web Audio API]

http://www.w3.org/2011/audio/track/issues/48

Raised by: Philip Jägenstedt
On product: Web Audio API

The duration attribute fills no purpose, as it can be calculated trivially from sampleRate and length.

In fact, the interface can be reduced to:

interface AudioBuffer {
    readonly attribute float sampleRate;
    Float32Array[] data;
}

The number of channels is data.length and the number of samples is data[0].length.

The name data was picked for consistency with the ImageData interface from the 2D canvas context.

We should hold off on this issue until the current discussions concerning "data races" are resolved.

We should hold off on this issue until the current discussions concerning
"data races" are resolved.

Agreed. I'm adding a bugzilla entry to track/record the discussions on the race condition issue, and will add appropriate dependency link.

Do we want to remove this parameter? (My vote is no, but it is not a strong position.)

Resolved by WG on 12/4/14: we should leave this as is, for compat reasons.
