Though, it is possible to remove unwanted noise from the audio stream afterwards, it is better to minimize your editing work. Furthermore, it is advised to use a high quality microphone. Built in hardware microphones, especially those from laptops, are considered to produce low quality recordings which include clipping, noise and therefore a low SNR.
