As far as I know vinyl in the old days was analog, meaning that if you
look on sound produced by vinyl (or tape or whatever) as a wave it is
smooth opposed to the digital media where a sound wave, if magnified,
is full of small "corners".
To my knowledge back in the old days all music was stored on
mastertapes thereby making the original recordings analog.
But how is it produced today?
Is everything stored digitally? Because if it is, vinyl today is
perhaps analog in practice but the recording on the vinyl is digital.
This means that it makes no sense whatsoever investing in vinyl.
'Cause the soundwaves are similar to that of the digital media.
Am I wrong in these speculations or am I right?
