allow me to comment as follows.
a lot of the old pro AE's that did the big classic hit songs
n who i respect ..many were self taught.
many were true engineers/building n modifying
audio consoles etc while recording hits.
so i'm frankly sceptical that a recording school or on line courses
can teach the "engineering mojo".

many people believe (i believe erroneously) that all they gotta do
is go take a course n buy top flight recording gear and a hit is assured.
unfortunately the recording gods laugh at this instant coffee approach.
i agree with the other folks..lots of info if one googles.
without spending money.

anyhoo..every song is different.
just cos a AE says i eq my vocs or drums this way in a course or that way
might only apply to that particular song he was working on
and what that song needed. your song might need a different treatment.

so in conclusion i feel best bet is just to get down n dirty n record
as many different talents as possible.
thats how lots of the old AE's started n honed themselves.

we all struggle with self doubt mate.
am i good enough ?? does this song suck ??
do i need a course at recording school ??
would buying that big audio console help me ??
when the true answer is..there aint no perfect answer.
or magic instant coffee solutions.
ive personally found self doubt can be a killer on creativity,
cos one becomes paralysed by analysis n second guessing.
best bet...one does the best one can and thats all one can do.
the TRUTH is songs are just hard work. with no easy solutions.
so sam..stride out n just do yer thing with a modicum of gear.
