For creating video or audio recordings where narration is required, it is worth the extra time to ensure that the recorded audio will be the best quality possible. For this reason, there are generally accepted best practices for recording audio.
Best Practices for Audio Recording
The first factor to consider is the microphone being used. For example, laptop or standalone desktop microphones may record more background noise and interference than headset or lapel microphones. Pop filters are also recommended where applicable.
Microphone placement is also important to consider, both to avoid popping and to ensure the microphone is picking up your voice clearly. The optimal distance and positioning depends on the microphone, and may require some trial and error.
Reducing background noise can dramatically improve recording quality. Closing windows, turning off fans, and closing doors will all reduce the amount of background noise in the recording.
When making a recording, it is also important to sit or stand in a comfortable position. Sitting comfortably upright will make it easier to breathe and speak, andwill make a difference in the end result.
Before purchasing a microphone, one should first consider how the microphone will be used. For public speaking and recording of lectures, a lavalier or clip on microphone will be most appropriate. The Sony ECMCS3 is a good example of a clip on microphone. Keep in mind that supporting hardware such as an audio recorder may be necessary.
For office recording, other factors should be considered. For most purposes, a standard analog microphone will be "good enough" when properly set up. A bluetooth headset such as the Logitech H800 will also work for this purpuse. Without taking measures to reduce background noise, a high-fidelity condenser microphone such as the Audio Technica AT2020 will not be necessary.
