Does this mean that we have been unnecessarily fussy about flac vs mp3 at 320 kbps ? Just asking since the graph looks almost identical.
Perhaps.
Measurements and numbers and graphs are usually flung away when it doesn't match our believes. (Numbers can't describe what I feel!)
BUT the same measurements and numbers and graphs are useful when we wish to profess our beliefs. (Numbers show that my beliefs have been right all along!)
