Sounds like a coherent plan, JJ. I switch things around frequently and listen for comparisons. I'll use your suggestions as I go. snip
Using the human voice as a reference has one big upside to it. That is, we are all quite familiar with how they sound and can tell, usually quite quickly, when it is closer to 'reality' than not.
And besides some songs are so good that being able to 'sing along', even if silently, can add to the enjoyment.
