It's a paper on sound theory.
The DRC control interferes with the original sound playback.
So to rewind this DRC control and regenerate the original sound,
Band EQ never plays original sound in flat state
through separate equalization adjustments
Reset the dynamic range of the audio to the level of The signal Noise ratio against of the device
The dynamic range of the original sound limited by the DRC control is restored to its original value
That's the theory that the original sound output is.
Please be you should to reference of the detail content to be all about at this dissertation from the following under link

Also
The good idea that reading of the this dissertation
(I want to compare with that the following state)
(I hope you should to be turn off the all sound effect and flatten a state to be your equalizer)
(I was recording by a G6 smartphone 24bit Hi-Fi recording program)
(Just not use to be V20 smartphone
(Both are product from LG(Lucky&Goldstar))
(Cause I was stolen My V20 at by someone in the past of my life)
(So)
(I hope you will excuse me to be not good mike performance)

If you take turns listening about that this two recording files
So
first recording file that was I did song of the YOUNHA,
And song title is ‘먼 훗날에’ (In the someday to be far, and far away)
(The song title is not an official translation)
And second
The recording from the studio at the same file
The listening point (If you do that)
First file 19 second and 3 minutes 35 second
Second file also 19 second and 3 minutes 33 second
I think you will get a feeling of comparison, very certainly
That is the two file
One thing is recorded by not equality volume
And the other thing is recorded by very equality volume
That called 'Dynamic Range'
To explain the Dynamic Range
Is this that the difference between the smallest and the largest sound volumes,
That the device can express or recognize
In other words 'Sound Width'
(I told you distance - or differential - of the sound volume)
(The distance of the sound volumes, that from smallest to be largest)
The file recording from me
That is not equality volume.
And the volume is repeat the increase and decrease with the flow of the time
But
The file recording from the studio
The volume of the file is never increases or decreases
No matter how long time it takes
I think you will get a feeling to that, very certainly
That is the secret
A common instrument or human voice is never not equality volume,
And repeat the increase and decrease with the flow of the time in the vibration or the act of flicking strings
That is the natural sound.
Or
That is the original sound.
However
The Act of to be narrower than the width 'That the Differential of the original sound volume' -Differential of the increasing or decreasing sound volume- is Called 'DRC Control' (Dynamic Range Control)
All about to broadcast sound And music production company And All singer's record, They was product a sound by use DRC control.
So
All that sounds was product on the equality sound width(volume)
Cause All that sound be far from natural sounds
(All that sound has distortion)
Thats a not a problem listening by use common device
On the contrary,
Protect to auditory(hearing) of the hearer(listenership)
And
prevent a fight(quarrel) from The Loud Sound Or noise pollution to the between Next door(neighbor)
And
Prevent investment of expensive soundproofing equipment in advance
Because they are use DRC Control in All Sound Production
BUT
Following Next Situation
So.
Not equal to the SNR(by use device)-Signal Noise Ratio- From the Dynamic Range(The sound source - apply DRC Control) is make a lot of the Distortion
For example
Listen to the music(Me) with Hi-Fi audio Or The other high-performance audio(vacuum tube or LP or both),
When The exceed 95DB SNR was make a situation that is the audio not lose sight of every detail of the sound source, but even in the narrower than the Sound width(Dynamic Range) of the sound source(apply DRC Control) that was must make a lot of the distortion
I'll explain what that means.
That means
A phenomenon occurs Just like bend a super-size reflection to be showing the IMAX screen in to the small-size computer monitor (in desktop)
So
These massive data to be integrated in to the narrow monitor, the data has become harder to distinguish the boundary of respectively frequency, because the data has wrap up in a slipshod way of they are(be tangled up) in to the small-size computer monitor (in desktop)
More precisely
The photo file size conversion is, It's what everyone has done
If you do the photo file 3MB size has conversion in to the smaller then size that file has the capacity must be reduced to the normal
And
That the quality of sound to the common device
This circumstances has not occurrence any problem to the sound quality
Because the file size that suits it (on that small monitor)
However
What size of the capacity of the original file?
Yes!
3 MB(megabyte)!
What happened was not reduced to the file size when has conversion in to the smaller then before?
Yes!
The File had to be the Broken (Files has crushed)
(It's a muffled sound)
Because, That is the influence of The DRC Control had to be the Hi-Fi audio Or The other high-performance audio(vacuum tube or LP or both),
These monitor(The screen) called Sound Width too much narrower then the what a massive data from the total amount of audio signals by the high-performance audio regenerated.
Also
That is the problem(or nuisance?) of the Hi-Fi enthusiast
(In Korea everybody called them 'The Hi-Fi mania')
When the listening the music on the state of the Flat sound(flat state equalizer)
That sound has too much distance far from the original sound(Too far away)
Cause I (or them) was keep adjusting the equalizer
So.
That problem is never be resolved before the 'Sound Width' (sound volume) has restored to its original state, and that problem was to be the dilemma of the love and hatred.
If you do that has restore the 'Sound Width' (sound volume) to its original state,
Then be well done of the Burn in the speaker,
And you can hear that the what a beautiful sound.
And, you can hearing with the same sound as the original, when listening by the common computer speaker that the just like the above the sound source that was has did recorded by me,
Because,
That source, The Changes in the volume size on the time flow, that was has did same(almost exact coincidence.) ratio at the natural sound of it.
(I was not adjust a same size of the 'Orignal Sound Width')
(I did adjusting ratio of the 'Sound Width' from the sound source)
(I did testing by my ear, and adjusting equalizer at the best ratio)
In fact,
If we did the come to the realization on 100% of the studio recording environment,
when the home studio has not investment of the separate soundproofing equipment,
That situation has a surely make to quarrel with Next door(neighbor) from the noise pollution.(by a noise travelling between floors. or between next door)
Because,
The broadcasting station's and record label's they has not make a music or sound just like before that,
And also,
I did just playing of original source, that was made by them
Never changed any data
Never
I just record by(from) my speaker sound.
(All that sound data from the CD -Compact Disk-
All them has the wonderful data
It's the all that data they was recorded from the beginning
Even made decades ago CDs are the same too,
Rather, the best quality of the original data,
That is the recorded in the 1990s)
Just
I was trying to the adjusting GAIN
And then, setting to the equalizer - input sensitivity -
(setting the 'sensitivity of speaker')
The situation of the high impedance of input section(input speaker) more then output section(power supply - it's mean's audio or amp-an amplifier-)
(That is the one technique of impedance matching.
The purpose is to obtain a decent braking force of the bass part during operation of the speaker. - Brakes the unnecessary movement of diaphragm,
This induces unnecessary currents generated during operation of the speaker to flow toward the lower impedance part of the power supply.
So...
It was Rather then very difficult for current to flow from the power supply to the speaker
As a result, there is an effect that a factor of cause unnecessary vibration of the diaphragm is originally removed.)
(The technique called 'damping factor')
I did, generated the necessary electrical power to the operating the speaker in the high ratio of 'damping factor'
(It was adjusting to the GAIN)
And
That is amount of current required has did subdivide by frequency band and that band adjusting differentiate, from the based on that electrical power to the manifest as the specific sound pressure by the speaker.
Until the here,
The story of the necessary of operating to the speaker(common Mechanisms)
And Normally, flat sound has been flow the equal amount of current to the input 'sensitivity of speaker' in the all frequency band.
I did intentionally,
This amount of current had to be the adjusting to different, on the basis of the subdivide by the all frequency band has discrimination.
Because,
By use the DRC control to the all about original sound source,
For example CD or the other digital sound source or all broadcast sound and film music, and all acoustic effects used in broadcasting and movies
That was why I had to do the adjusting equalizer to the all frequency band has discrimination, because of the DRC control
In the end
I did the restore to the state in which no distortion has been applied just like the original sound(natural sound) that's a way of the putting a distortion by the original sound source(CD) was putting a distortion from the beginning
