SongTime is a down-and-dirty little app to take the drudgery and guesswork out of figuring it out! Just run SongTime, enter in the BPM, Beats/Measure, and number of measures, and it will tell you not only how long it will be, but also frame and keyframe times as well.
Our Review: A handy litle tool for calculating how long a track will be depending on the tempo and beats/measures. So simple no documentation comes with the program. Good for composers who want a guide as to how long their track is likely to be.
