Modifying the sound output of a video file on a mobile device using the Android operating system involves altering the audio track’s gain or amplitude. This process can enhance the perceived loudness of the content during playback. For example, a user might find a downloaded movie’s audio too quiet and seek to boost its volume beyond the device’s standard output levels.
Augmenting video audio is beneficial for users with hearing impairments, environments with high ambient noise, or when the original audio was recorded at a low level. Historically, this required transferring the file to a desktop computer for editing. Current technology allows for these adjustments directly on the Android device, increasing convenience and accessibility.
