Session-At-Once (SAO) is a subset of Disk-At-Once (DAO).

It is used for Enhanced CD (CD Extra) recordings, in which the first DAO session is audio and a second DAO session is data. This is not to be confused with a standard multisession recording, which is data and recorded in Track-At-Once.

The Enhanced CD will play on a CD player just like a standard audio CD. The data content will be read and recognized on a computer just like a standard data CD-ROM.

The process called SAO-RAW as used by some software that defeats copy protection is not related to the standard definition above. The copy protection SAO-RAW is a method of reading and writing data in an audio-like process. This involves copying data in a RAW 2,352 bytes/sector mode that transfers intentional copy protection errors without higher level ISO data error correction.
