During audio mixing, which technique helps create a seamless transition between tracks?

Crossfading is a technique commonly used in audio mixing to create a seamless transition between two tracks. This method involves gradually decreasing the volume of one track while simultaneously increasing the volume of another track. By doing this, the listener experiences a smooth overlap between the sounds rather than a jarring cut from one to the other. This is particularly effective in music production and DJing, where maintaining the flow and continuity of sound is crucial.

Fading, while also a valid technique, generally refers to the gradual increase or decrease in volume of a single audio signal rather than the overlapping of two tracks. Normalizing adjusts the overall level of an individual track for consistent loudness but does not deal with transitions between multiple audio sources. Quantizing is a technique used primarily in MIDI production to align musical notes to a grid, which does not pertain to mixing audio tracks. Therefore, crossfading is specifically designed for the purpose of facilitating smooth transitions between tracks, making it the most appropriate choice for this scenario.
