Lesson 2 Sound Quality

    Lesson 002 was premiered on 9 August 2020. 

    However, the quality of voice-over left much to be desired. The loudness levels of each session are different. The voice is too loud in one session and barely audible in another.

    Fortunately, Audacity provides an effect that can solve this problem. It is normalized by root-mean-square.  I use the method to normalize all the voice recordings throughout this lesson.
