Before anything, that's not a "oh, where can I find resources?" question.

Well, I've been curious about one thing in the indie games industry.

For the development of the game, such tasks like game design, art, sketches, code programming and etc can be easily done by just one person. You can just take up a paper and pencil and you're a game designer. You can just take software like Photoshop or Paint and you're an artist, a scanner and you're a sketcher, a compiler and you're a programmer.

For sound it's different. You may tell me: Well, follow the line, take a lot of instruments and record it.

But all we know that things don't work this way. I can list up some changes for us:

External noises are a big problem, sound effects can't be made with instruments, it can't sound like a recorded and clipped sound.

Well I can imagine how they do this in large companies, with such big studios and etc.

But to summarise, my question is: What's the best way for a one-man indie to do all its sound?

Does he have to synthesize everything? Record and buy some crazy program for editing sounds?
