Types of Events on an Audio CD
There are three types of events that can be used to specify various sections of audio on the CD.
- Track start
There can be up to 99 tracks on one CD. Each is identified by its start point only.
- Track sub-index
On advanced CD players, a track can be divided into sub-indexes (sometimes called only indexes). These are used to identify important positions within a track. There can be 98 sub-indexes in each track. However, because it is difficult and time-consuming to search for and locate to a sub-index, many CD players ignore this information.
- Pause
A pause is added before each track. Pauses can be of variable lengths. Some CD players indicate the pauses between tracks on their displays.
