I should point out Web Audio developers make no such assumptions - we don't choose the sample rate of decoded buffers, the AudioContext does. I suppose if anything, the spec itself is making the assumption the AudioContext keeps running at the same sample rate.

I think the spec requires that anything played at a different sample rate to the AudioContext be resampled, since you can call createBuffer() to create a buffer at a given sample rate (e.g. 22050) and play it, and it presumably is resampled to the AudioContext rate. If the AudioContext sample rate changes after creation, shouldn't this kick in for existing buffers?
