Precision timing is whenever I have to meet certain time constraints in my recording.
Examples of precision timing include:
synching my voice to a video
dubbing my voice over another person’s voice
recording to a specific time length (like 15 seconds, 30 seconds, exactly 53 seconds, etc.)
recording within scripted timestamps
Precision timing takes a bit more time and work to record and deliver, so I offer it at a higher rate than for standard recording.
