What is the default audio transition in Adobe Premiere Pro?

The default audio transition in Adobe Premiere Pro is Constant Power. This transition is commonly used because it provides a smooth and gradual audio fade-in or fade-out effect. Constant Power works by adjusting the volume levels in a way that allows the transition to sound more natural; it effectively maintains a consistent perceived loudness during the fade.

When using Constant Power, the sound gradually increases or decreases in level, enhancing the listener's experience without abrupt changes that could be jarring. This makes it particularly useful for creating seamless transitions between audio clips or for fading audio in and out at the beginning or end of sequences.

In contrast, the other potential choices—Linear Gain, Exponential Fade, and Constant Gain—do not provide the same level of auditory smoothness, as they handle volume changes with different mathematical approaches. For instance, Linear Gain alters audio levels at a constant rate, which can sometimes create noticeable jumps or dips in volume. Understanding how these different transitions affect audio quality can help in making more informed editing decisions to achieve the desired sound design in your projects.
