SongKong Pro can use acoustic analysis to determine additional features of your songs. With other solutions the software has to listen to each song to calculate the acoustic analysis, this is time consuming and CPU intensive. But SongKong Pro does not have to do this, the songs for nearly three million songs have already been analysed and results of the acoustic analysis is already stored with the song in the Albunack Server, so there is no additional time required to add fields calculated via acoustic analysis.
The three well defined fields that can be calculated are:
BPM
Key Scale
Mood
The algorithms used to accurately calculate these three measures are still evolving and can be done in different ways. So SongKong gives you the option to only add these values if they don’t currently exist in the song, add regardless and overwrite any existing values or not add at all. All these options are ignored if Update Mood and other acoustic attributes such as BPM is disabled on the Basic Options tab
