Certain singers are not sufficiently seasoned to shade sibilant and hard consonants themselves. Engineers often use pop filters and de-essers (or other special compression) to eliminate the effects.
A pop filter is a kind of physical barrier that prevents the popping sound of hard consonants (such as
p) and, to a degree, lessens sibilance at the first level of recording (a pop filter can be a nylon stocking stretched across a coathanger bent into the shape of a diamond). It is placed in front of the mic before the singer begins to record or whenever the problem first appears during an initial or overdub recording session. De-essers, on the other hind, are most often used afterward, during a mix.
In my experience, such methods are not always used in classical and jazz recordings. What's more, engineers' emphasis of higher frequencies in mixing and mastering can worsen the sitch. Then, too, if a line in a verse overuses the letter s, the line is partly at fault. Personally, when I write lyrics for an artist, I actually underuse s, z, ch and sh and strive to use as many liquid consonants as possible, reserving hard consonants for rhythmic emphasis. My personal models in terms of avoiding sibilant lines: Christina Rosetti, John Keats and Ernest Dowson.
Note that I'm using the word
sibilance in both the original (correct) and engineer-specific (neologistic) sense.
From
Bartlett's Glossary of Recording Terms:
Quote:
SIBILANCE: In a speech recording, excessive frequency components
in the 5 to 10 kHz range, which are heard as an overemphasis of
"s" and "sh" sounds. |
From
Merriam-Webster's Eleventh:
Quote:
sibilant (adj.): having, containing, or producing the sound of or a sound resembling that of the s or the sh in sash (a sibilant affricate) (a sibilant snake).
Etymology: Latin sibilant-, sibilans, present participle of sibilare, to hiss or whistle. |
(PS: For an example of undesirable sibilance, read the first line of my post aloud.)
