To get your tracks ready, you must first add sound files to the RecordForAll Library. Any track in the Library is then available for you to add to a Playlist.
When you add a sound file to the Library, RecordForAll automatically builds a plot for it. RecordForAll uses this information to determine how to mix tracks for tracks Crossfade Mixing or Beat Mixing.
Because processing a track can take anywhere from a few seconds to a couple of minutes, depending on machine speed and available system resources, RecordForAll works in the background whenever it's open, until all of the tracks have been processed. If you have a lot of files, it could take several sessions for RecordForAll to process all of them.
