Having said that, the audio capture hardware has a specified area (as an imaginary cone) from where it is able to capture audio signals the best. Audio waves that propagate through the length of the cone can be separated from the audio waves that travel across the cone.

Quite often we may find ourselves to be in noisy environments where different background noises and irrelevant sounds could corrupt the quality of our audio stream data analysis and/or the speech recognition.
