I acquired a new laptop recently (hooray!), unfortunately it has no line input to record sounds from vinyl or cassette (boo!). I certainly wasn't brought up around digital technology and I have this kind of blind faith that things should just work. As such, when I plugged my mixer into the mic input of said new laptop, I just expected that the recordings would be fine. How wrong I was, the last post sounds absolutely terrible. My apologies for that, and a rerecorded version will be posted as soon as possible as I have now found a solution to the recording conundrum.
Thanks for your patience people!
