Nero is a flexible, reliable, and easy-to-use application designed to write to both CD-R and CD-RW discs. It supports ISO 9660 images, as well as ISO mode 1 and XA mode 2, and allows for on-the-fly disc recording, in addition to overburning (if supported by hardware). Nero also supports multisession and mixed-mode recording; HFS, ISO/HFS hybrid, UDF, PSX, OFAS (optimal file access speed), track-at-once (TAO), and disc-at-once (DAO) writing; and digital audio extraction. In addition, Nero can dynamically disable automatic-insert notification, and it offers support for multiple languages.
Recent updates added a full-featured WAV editor with a range of audio processing options, real-time effects, a settings manager, an advanced cover designer, a drag-and-drop MPEG-1 video encoding feature, an audio plug-in interface for new audio formats, and a drive toolkit for benchmarking and adjusting drive speed.
