Downbeat

Downbeat provides an easy way to determine a Music Files tempo in BPM (Beats Per Minute), and was written for DJs or anyone who is interested in beat mixing or creating music. Many of todays music software packages rely on a tracks BPM value to enable beat mixing. Furthermore, this application can automatically analyze all your music library by simply pressing a button.
Downbeat provides an easy way to determine the BPMs for a batch of music files. Once the tempo for the batch of files has been calculated, that value can be written to the ID3 tag of each file and stored for future reference. If you dont want to write the value to the file meta-data, you can export your BPM analysis list to Microsoft Excel, if you have that software installed on your computer.
