Audio Calculator converts BPM to time and vice versa.
If you're into composing music on your computer, you'll probably appreciate what this lil' fella does. Type in the tempo (BPM - Beats Per Minute) and it calculates the duration (in milliseconds) of a certain number of notes or beats. Perfect for manually setting delay/echo times or the frequency of an LFO.
The Audio Calculator also does the exact opposite. You have this little sampled loop, and would like to know the exact tempo (BPM)? Just type in the duration (milliseconds) and the number of notes/beats, and voila!
The Audio Calculator is very accurate, and works just fine with decimals (after the ".").
