4.6.1.3.2 Chord Sets <chord_sets/>

Chord sets are the building blocks of sound effects that use synthesized rather than sampled audio (most call progress and ringer sound effects). A chord-set is a multi- frequency note with an optional on/off cadence. A chord-set can contain up to four frequency components generated simultaneously, each with its own level.

There are three blocks of chord sets:

callProg: used for call progress sound effect patterns

ringer

misc (miscellaneous)

All three blocks use the same chord set specification format.
