When duplicates are found, SongKong decides upon the song to be kept and the songs to be deleted based on the order of this criteria. The first item in the list is used to compare songs, and only if all the songs for that key are found to have the same value for the criteria does additional criteria get used in the order they are listed. To change the order of the criteria click on the criteria you wish to reorder and use the up and down keys to move into position.
Keeps the file format that comes earlier in the Preferred Audio Format list. By default SongKong keeps FLAC or lossless files, wherever possible. You may prefer lossy files if you want to save space on your music player. To change the order of the Preferred Audio Format select the audio format you wish to reorder and use the up and down keys to move into position.
Bitrate describes the number of bits or amount of data that are processed over a certain amount of time. In audio this usually means kilobits. For example, the music you buy on iTunes is 256 kilobits per second, meaning there are 256 kilobits of data in every second of song. The higher the bitrate of a track, the more space it will take up on your computer. Generally, an audio CD will take up quite a bit of space which is why it has become common practice to compress those files.
If bitrate is your preferred deletion criteria then SongKong will keeps the song with the highest bitrate. It doesn't usually make sense to compare the bitrate of different audio formats, so this criteria should always come below the audio format criteria.
When your preferred deletion criteria is Track Length SongKong keeps the longest song and assumes that the shorter version of the same song may be incorrectly clipped.
If your preferred deletion criteria is Filename SongKong keeps the file name that looks like the original file by looking for words such as Copy in the file name.
