Also, make sure where you are doing the recording is a suitable spot because surrounding noise can ruin the audio, such as the sound of passing vehicles, lawnmowers, and even the breeze. Also, don’t record in an empty room because of echoes, instead, stay in a room with furniture and other items because they dampen echoes.
