How to listen to music in 1950
I hope someone can help.
I'm writing a screenplay set in 1950 and it's about the making of a movie.
I want to include a scene of the producer listening to audition tapes to find the right voice.
I could do this in numerous ways but I'm not looking for alternative suggestions - I just want to know how somebody would have done this before cassette tapes.
How can I have someone listening to a dozen or so individual auditions?
The studio are rich and can use state of the art equipment - there's no limit really.
I just want to know the best possible way for someone to be given a heap of recordings and sit listening through them all.
Any help is appreciated.
