For those of you who are really curious and want to know more than you probably should, I will write my informal thoughts here and may update occasionally.

The audio processing that I have constructed is a combination of digital tools I have painstakingly auditioned, selected, modified, and calibrated to control their behavior toward arriving at the results I desired.

Comparing this treated audio to the original audio will not "blow you away". If the result accomplished that, anything more than brief listening would soon cause "listeners fatigue". My actual result is more subtle. Subtle is powerful in this case. The advantage sets in over time. It begins to take hold at around 11 seconds and continues throughout the listening process, sometimes subconsciously. Many people notice an enticing sound quality. What they are hearing is actually not entirely present in the sound but rather added by the auditory part of the brain in response to certain waveform actions in the audio. That is part of the science of psychoacoustics, which I won't go into here. I almost believe I shouldn't have mentioned it because what I understand about this topic is dwarfed by what I don't understand. But if you are curious and want MORE, look up "missing fundamental" "frequency masking" and the subject of psychoacoustics in general. I will point out that we do not hear pure sound the way it travels through the air. Our brain modifies it and completely rearranges it. I would guess that if we could hear sound in its pure state, it would sound ghastly. Speech would not be understandable because we would only hear the formant intervals instead of the formant sounds. Music would be a muddle of unpleasant noise.

The specific sound flavoring that results from my recipe of processes is very elusive but I don't have a monopoly on it. I am aware of only two other sources in the world that can produce this audio mastering result. One is in a most southeastern part of the U.S. where commercials for some of the big brand names are made. The other may be in between Russia or somewhere that direction. Then there is me. In the southern U.S.

So, you already have great audio in your project. That's good enough.
Good enough wins the day. But when winning the day is not enough, there's excellence.
Where good enough wins the day, excellence keeps going, and growing.
