While some reading this may be more advanced, just as a precaution, I've decided to start at a basic level. If you are familiar with audio mixers and how they work, just move on to the next step.
When you are recording your voice and a second voice (or more audio elements), it's general easiest to use either a hardware mixer or software that emulates a mixer.
The diagram I have created demonstrates how this simple process works. Your audio goes into the mixer, each element on a separate "channel". In this example, your microphone is channel 1, the telephone audio is channel 2, and a CD player is hooked up to channel 6. Click to see diagram.
You use the controls on each channel to adjust that channel's volume. When you have the overall sound as you like it, you begin your recording session and the mixed output of all three elements leaves the mixer via the LINE OUTPUT JACKS where wires take it to the LINE INPUT JACKS attached to the soundcard of your computer.
This example demonstrates a traditional hardware mixer. Although there are a multitude of software applications which emulate hardware mixers, in order to do what the hardware mixer can do, your computer must have a sound card which accepts more than one stereo channel of input.
Most sound cards are not setup for more than one traditional channel of input. There are more sophisticated sound cards but that is not the focus of this material.
