so i know all you tech wizards out there in the internet world could help me out...i have a question.
i've been working on compositions for films ever since i became a film school student officially around this time two years ago. i've gone through many phases of development since i started making music about four years ago, and a lot of my techniques have changed over the years.
however, now that i'm starting to really get serious with filmmaking, i've been running into a bevy of new issues involving things such as sound design and scoring. i basically know what i want to do musically with each piece, and typically my style tends to be more minimalist electronic than anything else in the film world...but there are certain things i haven't been able to figure out quite yet.
namely, age. i have a hard time aging a piece of music i created on my laptop, and making it sound as if it were possibly recorded through analog means way back in like the '70s or something. i'm sure you're all aware of the diff's in sound quality throughout the years of film/television -- everything nowadays is much crisper due to way better technology, but if for example i was creating a mockumentary based off of a mix of the Jacques Costeau nature films from 40 years ago and the government-sponsored propoganda films/PSA's from 60 years ago, idk how i would exactly want to filter and EQ the mix to make it sound like it came from that era.
a good example of this type of nostalgic sound design is the [as] show Look Around You, which is basically the direct influence for what i wanna do...just really dry humor that essentially takes a banal subject like water and narrates all the facts about it completely wrong, like saying the world's supply of freshwater comes annually out the cock of Liam Neeson or something haha, but just filming it in an astute, serious tone. but the whole premise of that show was that it was made to look like a boring educational film from the '70s that you'd watch in like science class or something, and their sound design is expertly coordinated to make it really sound like it's from that time.
so tl;dr how do you make an audio mix sound as if it is much older than it really is? (and please no simplistic "vinyl simulator" bullshit, that's not exactly what i'm asking -- it's more along the lines of making something sound like it came from like a reel-to-reel tape or something.)
