For a simple audio project - stripboard will work just fine.I'd like to get the circuit off my breadboard and be able to build other circuits, so I thought about trying a perforated board, but read that they can experience a lot of noise because the component leads tend to act as antennas. I'm aware of wire-wrap boards as well, but they seem like a real pain to use. I guess there aren't really any good alternatives to soldering for what I'm doing?
You can mount the components flat to minimise adjacent parallel component leads, but stripboard isn't cheap and the end results take up more space.
As I'm a skinflint, I always mount components vertically to get away with the smallest amount of stripboard possible. AFAIK: noise isn't the problem, you can run into stability issues at high frequency, but you should be able to get some considerable way past the AM broadcast band before that happens.
In actual fact:- laying the components flat can end up as a nice little antenna array - you could end up having to mount it in a die cast box to eliminate unintended RF reception!
