CS_get_color( ) derives a color from a
sig, /* signature array */
CS_RGB_Color color /* color array */
||Identifies an array containing a
signature that was obtained through a call of
||Identifies a three-byte array into
which this function will store a color represented by an RGB
triple. The first byte of the array will receive the Red
component, the second byte will receive the Green component, and
the third byte will receive the Blue component. The value
of each component ranges from 0 to 255. When each
component is assigned a value of 0, the color is interpreted as
black, whereas if each component equals 255, the color is white.
This function performs a mapping from the sonic universe to the RGB color
space. In rough terms, high-pitched sounds receive more Red
component; low-pitched sounds are mapped to dark colors; mid-range
sounds tend to be shades of Green or Blue; and noisy sounds (such as
idealized white noise) are assigned shades of gray. An invalid
signature is mapped to black.
The color obtained from this
function is useful for display purposes, especially for coloring an
audio waveform display.
This function has no effect if the
color parameter is NULL.
