The fact that new strawman use cases keep getting introduced without remedying this problem is a little bewildering to me. If the cost of building test cases to support your arguments and then gathering data is too severe, we could look at all the major Web Audio applications out there in the wild and see if the additional copies/memory usage in FF's implementation causes them to perform worse.

To be fair Chris (and Jer) has also repeatedly given examples of the maths involved.

See for example this, by Jer:

An actual demo or example would of course be valuable.
