My experience is largely with voice, and so please don’t look here for advice on editing music…
Today we look at a couple of goals to keep in mind when editing sound: Consistency and Continuity.
One of the main problems with weaving together sections of audio that were recorded at different times is that the background noise, the volume of sound, and overall fullness of a voice will vary.
This happens even when you try your best to recreate the same recording environment. It can be even worse if you change locations or microphones or the software being used to clean and record.
So, try to clean the sound thoroughly so that background noise is not an issue. Level the sound over the entire final clip.
The hardest one is giving the voice the same depth or richness. The best way to achieve this is to use a good microphone, record in a place without too many reflective surfaces, and always have the microphone at the same distance. In other words, try to keep a constant fullness in the voice – since it is very hard to fix later.
Another key problem when putting voice fragments together is making sure the edit points are not audible. The best way to avoid this problem is to use a good editing program.
Also, when making your initial recordings, choose logical places to stop. Don’t stop in the middle of a paragraph. Try to get to the end of a section or chapter. This way, any subtle but sudden changes in the sound are unlikely to be noticed.
