Altering the perceived highness or lowness of the audio component in a YouTube video involves modifying its pitch. For example, a voice in a video could sound deeper or higher than its original recording through pitch modification.
Adjusting auditory frequency has applications in various scenarios. It can be employed to correct imperfections in audio recordings, create comedic effects, or render content accessible to individuals with hearing impairments. Historically, sophisticated audio editing equipment was necessary for pitch modification. However, contemporary software and online tools have made the process more accessible to a wider audience.
