Some Terms Used in Audio Recording

Fade-in The gradual upping of audio from zero to an optimal level. The duration it takes to reach its peak is called attack.

Fade-out The reverse of a fade-in where the audio gradually falls to zero. The duration it takes to fall to zero is called decay.

Cross-fade A transition method where the preceding sound is faded out and the succeeding sound is faded in simultaneously. Both sounds overlap briefly during a cross-fade.

Fade under A procedure where one audio is brought down to a level lesser than the primary audio. For example, music is faded under when a person is speaking on screen. It must be remembered that the two sounds do not clash but rather supplement each other.

Sweetening The process of working on sound after studio production is called audio sweetening. This involves incorporating additional material, making corrections, cross-fading, enhancing sound elements, blending various tracks, ensuring continuity, bridging, dubbing, and adding effects.

Phase cancellation This is a phenomenon that results in low and hol­low-sounding audio when two or more mics pick up sound from the same sound source. Since the sounds arrive at the two mics at two different times, they tend to cancel each other and result in hollow or low audio levels. Therefore, placement of mic is an important factor to get the right audio with greater fidelity.
