Hi Glupson & Perkri
You weren’t overlooked, I just wanted to see how far off track and topic things would get here before doing much more posting.
You are both on target here "unwanted" vibrations. As Glupson said "audio is vibration" and according to the Fundamental Interactions he is correct, there is no such thing as non-motion here on Earth. You can’t logically say "kill all vibrations" on a moving planet and it make sense. The Earth doesn’t stop spinning just because someone on an audio forum says so. That’s a little on the crazy side of things.
So here you have the audio signal, which is part language and part energy in motion. You have a legitimate change called volume. Volume is when you add energy to the signal. The energy itself is Vibratory. You can call it "put into motion" or "force" or several other names but Vibration covers the audio realm pretty well. Volume is an amplification of the vibration (audio signal) and when used all the Fundamental Interactions of physics also amplify and or interact. This is where the balancing act between interactions starts to play out in audio. When you increase Electrical, Mechanical and Acoustic energy the values of the new setting have to balance themselves out again. This is where you get either "true gain" or "distortion". True gain is an increase in the function of fundamental frequency and harmonics in balance (harmonic structure) that make up notes or band of notes. Distortion is when the fundamental frequency and support harmonics are out of balance. It can be too little vibratory structure or too much, either one is distortion. The fundamental interactions are what I call a "fair exchange" of energy.
Whenever something in Earth’s energy realm goes out of balance the 4 Fundamental Interactions (forces) go into action to put the fundamentals and supportive harmonics back into tune. The shape of being in-tune is a sphere. Reason being is a sphere can give off and take on energy exchanges with a natural vibratory interaction. It’s like a 3d oscillation or pulse. Without interacting force the Earth along with every planet or star would crack apart and loose it’s pattern. Just like when something is out-of-tune it means the supportive energy is out of balance with the fundamental cycle. The cycle out of balance is then called "distorted" or incomplete in motion.
