Nope, it's still an open issue here and for enforcing minimum delays in loops.

What do you mean by sample-rate-independent in this context?

If two implementations running at the same sampling rate don't sample AudioParam at exactly the same interval (in samples) then they won't sound the same. My favorite example is when the AudioParam is a high-frequency sine wave, where the result of sampling every n samples and every n+1 samples may be audibly different. I think that in order to define the sampling in terms of seconds, the AudioParam must also be correctly down-sampled to avoid this.
