sampling & recording streaming data from 1/8" audio input
I'd like to record sampling data from an instrument (guitar, keyboard, etc.) hooked into the audio input via a 1/4"-1/8" adapter into, say, a .txt or .dat file to be manipulated in ways undetermined at the present. Could I use my audio input as an istream object, writing to a file which another could read from simultaneously? This is my first time trying something like this, so I'd appreciate any help I could get.

1) Get yourself a library.
2) So you want to write binary data into a *.txt file?
3) And you'd like to write and read from a file stored on your hard drive at the same time? Don't you think that would be a bit lame? Apart from the fact it won't work. Such functionality is implemented by a buffer class.

1) Sorry, I know I'm a nûb.
2) I'm trying to create a magic function where I can set i=0 then be like sample[i] = guitarSignal.get(amplitude), i++. and then be like outputFile << sample[i] and write a space or endl that shit
Look basically what I'm trying to do here is create an array of one-channel amplitude samples from the audio input with a known sampling frequency.

Then, what's the big hold-up? You have a pretty concrete concept, now realize it. You could already be writing Guitar::get();.
Not really as concrete as you think, considering I don't know where to go from there. I don't know which functions exist that would return the amplitude of the input signal. I have pretty limited experience in OOP and in using classes and all, so... hold my hand, Magnus. I want to feel you. mmm.... that's nice. so baby,
would I create a class called, say, Instrument? For which any input signal could be assigned to an object of the type? And then would I define an operator to "sample" the signal? aka to return the amplitude of the signal as an int or whatever. If so, how would I write that operator? I could do the rest if that's how it would be done, but I'm unclear as to how to actually sample the signal.
