In AUDIO, fading one sound down while simultaneously fading another sound to replace it?

• A. Crossfading
• B. Ducking
• C. Panning
• D. Compression

Answer: (A)

The technique being tested is crossfading: you fade one sound down while simultaneously fading another sound up, creating a seamless transition between the two. By overlapping the outgoing and incoming tracks, you avoid gaps and keep the audio space continuous. In practice, you blend with two faders so that as the first sound decreases, the second rises, often with a brief overlap to maintain consistent loudness. Ducking changes the level of one element in response to another (usually lowering background music when dialogue or a primary signal appears), but it doesn’t describe a deliberate cross-over between two sounds. Panning moves a sound within the stereo field, not how its level relates to another sound. Compression tightens the dynamic range of a signal, again unrelated to transitioning between two different sounds. So the correct term for fading one sound down while fading another up at the same time is crossfading.
