You should realize that off-line processing is NOT inferior to real-time processing. It simply means that processing is not performed at the input rate, i.e. it is not synchronized with the playback. Off-line processing may be much faster than real-time processing! On a fast computer (and we don’t necessarily mean Cray) DART XP Pro will process audio data at ‘supersonic’ rates allowing you, for example, to restore an one hour 44 kHz stereo recording in 30 minutes - or faster. This means that listening to the results may take you much longer than restoration of the original recording...
