I've recently purchased a nice microphone and recording setup. However, my environment isn't as quiet as I would like.
My goal is to make voice tutorials for software developers. I own a fair count of licenses to what I feel is high quality stock music. Am I right to think that putting in a faint background track would be a good way to cope with the noise floor while still providing clear, intelligible speech? Or, will I just make it harder to hear?
My question presumes that a soundtrack is a good idea.
How does one choose the balance between voice and soundtrack, in volume terms? Is there a standard rule of thumb? Is there a way to measure it? Do people just go by ear?
