This tool calculates a given length in seconds of
an audio sample into temp in BPM and reverse. You
can also adjust Number of measures and beat resolution.
Length can be read directly from wave files.

Also included a calculator for time/tempo stretch rate
calculation if you want to adjust tempo or time to a
fixed value (e.g. matching to the tempo of a sequencer
song).

Length of a song can also be calculated from tempo and
number of measures as well as length of single notes.
Additionally the frequency of note lengths is
calculated (e.g. for oscillator adjustment)

An integrated beat counter allows DJs to measure the tempo
of a running song.
