Adjust the position of the microphone to reduce unwanted noise (e.g., breathing, popping Ps, whistling Ss, or rustling sounds from clothing).Adjust the recording level, proximity to the microphone, or recording environment, until your recording approximates the picture shown below. Although the microphone has a limited range, it might still pick up electrical interference from lights and fans, which may elevate background noise in your recording. When you are not speaking, this level should be as close to zero as possible. Playback some “silent” regions (with headphones at maximum volume) to detect any unwanted background noise. Move your cursor to the start of the wavform, and hit play to playback your recording and monitor the levels in the Playback Meter. A fuzzy baseline means there is interference or ambient noise in the background. Periods of silence should display as a thin horizontal line at 0.0. The waveform should be centred on 0.0, and never reach maximum amplitude (1.0 or -1.0 on the graph). After 10-20 seconds, hit stop and inspect the tracing. You should hear your voice through the headphones, and see the waveform trace out on the timeline.
