Illustrating the Transformation of Signals Over Time
An audio signal operates within a time-domain
, showcasing the evolving nature of the sound waves as they progress over time. This domain's values offer insights into how the audio signal is changing, rooted in a derivative of the fundamental wave equation.
In cases where a signal remains constant, the resulting audio signals would display no variation, likely returning values of 0
. The fluctuations in the signal are represented through this time-domain, allowing for the creation of visualizations such as graphs (typically oscillatory in nature).
The values themselves denote alterations in the signal's amplitude, reflecting changes across all combined tracks, as emphasized by the mention of it being down-mixed.
