What is DAO?
This is a method of recording to CD in which the disc is written all at once without interruption and without the recording laser turning off. It is generally considered the "professional" way of recording a CD. Best of all, DAO allows you to record separate tracks onto CD without the audible gap between each track. This makes DAO recording ideal for splitting your long WAV mixes into smaller segments and burning each segment as a track on the CD. CD Burning software supporting DAO recording: Windows -
