Should there be an upper limit for the length of the impulse response buffer? If a huge buffer is used this could easily completely destroy performance. If there are no practical uses for convolution over a certain size, we could just limit it and avoid different implementations having different internal limits and having to reverse engineer the competition to figure out what the Web-compatible limits are.

Do we have any limits on the dimensions of , or size of objects in WebGL? I'm just trying to get an idea if we have any examples to follow here.

If we do make a limit, then I'd like to make it rather high, like > 1 minute

We should not have a limit. You'll end up with a CPU issue before a memory one here, I think.
