SampleCalc

This tool calculates a given length in seconds of an audio sample into tempo in BPM and Reverse. You can also adjust Number of measures and Beat resolution. 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 can be read directly from wave files. The duration of a song can also be calculated from tempo and number of measures as well as length of single notes. This may help you to set delay (or other time dependend) settings. 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. A metronome can be run according to counted tempo. Metronome tempo can be changed.
