I often get tasked to record long scripts with many short segments. I have found that it is usually better to record the entire script, instead of recording individual segments. This allows my to concentrate on the performance, instead of having to change focus by stopping the recording and saving a smaller file.
When you do a reading in this manner, feel free to re-read portions throughout the script as necessary to change emphasis, correct problems, identify the best phrasing, etc. Just continue the recording, with your alternative takes of various segments. You can then edit the recording of the performance later, and cut out the problems.
When recording large portions of a script with multiple segments, when I reach the next segment I pause for 2 seconds, say “Next”, then pause for another 2 seconds prior to starting the subsequent segment. This short statement is easy to identify visually within the editing display.
I also apply general processing to the entire file, prior to editing. This would typically include applying a noise gate and EQ to the entire file. This helps ensure that all of the segments get the same processing treatment, and will sound similar once edited into individual files.
Once I have done the edit for content, I have a master file composed of the individual segments separated by the word “next”, in a manner that I can visually identify. I then cut out each segment, paste into a new file, and save the new files as the individual narration segment.
