is it possible to make digital audio sound like vintage vinyl

sam here with another question. is it possible to make digital audio sound like vintage vinyl ? i realize i'm gonna get ripped a new a-hole however this is not a joke question. honest answers please i can take the heat

as crazy as it sounds it seams perfectly logical to me. now here is what i did using my 2013 dell pc windows 7 32bit.

using foobar 2000 with the convolver dsp filter i made an impulse file consisting of a 1 second wave file extracted at 32 / 88 

from the intro to pink floyds us and them on 1st press vintage vinyl u.k harvest label. just the surface noise before the music 

starts and applied the impulse file to a digital album to see if the digital album now sounds like vintage vinyl.here's the results

not sure if i made the digital audio sound worse or really what i achieved ? feedback will help me decide if i should

abandoned this pipe dream and move on. source is digital download flac 16/44 same source for both before/after samples.

sam here,something else i noticed that i believe is hampering my efforts at making digital audio sound more like vintage vinyl              https://postimg.cc/LJQZYNF2 

and even when you lower the volume on the digital file the compression remains?

for some reason when the audio has more dynamic range as with vintage vinyl the sound stage is more open with less distortion.

 i believe if i can remove the digital compression this will get me closer to the sound of vintage vinyl.

i have tried numerous denoisers and declippers however they seem to make the audio sound worse? or at best different like somethings missing?

after doing some experimenting i stumbled upon a free foobar2000 filter called IIR dsp plugin. it has a preset called allpass  and when i run the digital audio through the allpass filter the digital compression is gone.

i'm not sure what the intended purpose of this filter is? the difference in the before/after sound quality is amazing here are my settings for the filter. https://postimg.cc/jCbxQmTv

i had to use replay gain to prevent clipping due to the increase in dynamic range. to check that my results are correct i ran another test using the worst loudness war offender i could find. metallica death magnetic. https://postimg.cc/bSvSYwzY

A few things digital generally doesn’t do nearly as well as analog. Air and squeaky sounds and applause. Oh, and raindrops.

And another thing. Digital actually doesn’t do bass very well, analog is juicy like Lucy. Harmonically a lot more realistic. Your preferences may vary.

Actually, a good hi-res digital recording of an LP does capture much of vinyl's LF juice and tonality.

sam here again and this time i made an impulse file for processing digital audio from an 8-track tape from 1978 100% analog not sure if any of that sound was transferred to the digital album. due to the placebo effect i’m not sure if it made any difference please listen to before/after and let me know if you can hear any difference when the 8-track impulse filter i made was applied to sample (2) and if so did i make it sound worse?
