Altering the perceived highness or lowness of audio on YouTube videos can be accomplished through various methods. This manipulation affects the frequency of the sound waves, resulting in a higher, more squeaky sound or a lower, deeper tone. As an example, shifting the audio of a musical performance upwards can make instruments and vocals sound brighter, while decreasing the audio pitch might lend a darker or more serious quality to spoken dialogue.
Modifying auditory frequency on this video platform offers multiple advantages. Creators may use it to creatively enhance content, correct audio recording errors, or produce unique sound effects. From an accessibility perspective, altering auditory frequency can aid viewers with hearing impairments who may find content more understandable when pitch is optimized for their specific needs. Historically, these audio editing capabilities were primarily found in specialized audio software; however, the rise of accessible web-based tools has broadened their availability.
