RE: Measuring digital audio qualities of bit-perfect playback with Diffmaker's correlation depth

Two questions:

1. How many times did you repeat each experimental condition, and if you did so, how consistent were the null depths?

2. How does the software distill differences of an entire file down to a single number? What specific algorithm is used and what are its parameters? Examples: L-2 norm (a.k.a. RMS) depends on a time constant, which could be a fraction of a second or it could be an entire track. L-infinity norm uses the largest absolute value of a set of samples, again which could be an entire track.
