Problems with your test methods ...

Some good points here. Having sounds compared by using phasing is kinda of pointless. In general when generating any kind of extra processing it's hard to keep track of possible added variabilities along the way.

All you need to do is take pcm data straight from the input wav and encode. Then decode to wav and extract and compare the pcm data. Since pcm data contains only raw audio samples, you can just bit-compare the results. Nice and simple. A difference between two values in this case can mean one of 3 things- the encoder is buggy, the decoder is buggy, or the underlying mathematical algorithms are spotty.
