From the MITx Media Team:

Picking the right place to record your lectures is more important than buying the right headphones or editing software because the best way to deal with audio problems is to prevent them from happening.

•Find a quiet room/remove ambient noise (request the people around you to keep their voices down while you are recording. Cover the floor with rugs to dampen the sound coming from neighbors. Objects like drapes, towels, books, linens, etc. act as natural insulators if you place them up against walls through which sound is coming)

•Create an outline/take notes

•Control Your Breathing (Breathing is another factor that can disrupt the cleanest recording. That is why it is important for you to learn to time your breathing while creating a recording. Make it a habit to turn your head away from the microphone every time you take a breath so the breathing isn’t picked up in the recording)

•Avoid Popping & Sibilance (Popping is the extra burst of air that is released from your mouth upon pronouncing Ps and Bs. Sibilance is the hissing sound the mouth makes when pronouncing Ss and Fs. Both popping and sibilance are picked up extra clearly in recordings and distract from the audio)

•Stay hydrated

Remember, you’re not professional audio and video technicians so don’t try for perfection. Relax, speak like you would to your students (include the stutters, no one speaks perfectly), smile and have fun.
