Well, I think that making a noise cancellation system can be a bit more complex than just taking the opposite of the sound samples (depending on what you are trying to do).

Typically, sound signals are represented as arrays of either integer of floating point values, also known as samples. There are many ways to represent an audio sample, but the floating point representation usually works best since it results in less loss of precision during processing since it tends to attenuate quantization issues.

Good reading material is available in Wikipedia, here[^], here[^] and here[^]. A few years ago I have also written an example on how to record an audio signal from the microphone in C# using SlimDX.[^]. I hope it helps (at least to get started with audio processing).

Best regards,
Cesar
