Click Book, also known as a Click Track Book, is a utility designed for film composers. By entering a specific tempo (in beats-per-minute) you are given a list of timings represented by minute:second:fraction-of-a-second (ex: 2:37.88). Every beat's timing (quarter notes, if for example, you are composing in 4/4) is displayed with the actual millisecond offset from the beginning of the music. Film composers have used the click book to help decide on the best tempo to compose in by how closely based each timing is to the "hit" (or event) of the scene. Toggle between displaying the entire list of "clicks" as one continuous stream of timings or display the list in sections where each section represents a musical measure. The "display measure" mode helps in visualizing where each hit point falls in the musical score. You can choose to display each measure with a specified number of beats per bar. For example, enter a "4" and that would imply a musical timing of 4/4, 4/8, etc. Browse tempos from a list of pre-defined click tempos ranging from 6-0 (240 bpm) to 28-0 (51.43 bpm). Save any tempo to an editable favorites list for easy tempo comparisons. ClickBook is a Universal app for the iPhone/iPod Touch/iPad family of devices so that each device's screen resolution is taken advantage of. If you find this app useful, please let us know.
