By PSW Staff • April 30, 2010 Backline Calc 2.0 Audiofile Engineering has released Backline Calc 2.0, an update to their audio calculator app for Apple iPhone and iPod touch. Backline Calc is a valuable tool, featuring more than 20 calculators and converters. “Playing, teaching, practicing or writing music, mixing live sound and producing music all involve calculations and conversions of musical and technical data,” says Matthew Foust of Audiofile Engineering. “Backline Calc lets you calculate musical, acoustic, video and even electrical data quickly and easily, so you can get on with the music and not the math.” The Backline Calc app is free to download and includes three basic calculators: Note Length, Frames to Time code, and File Size. The rest of the calculators can be purchased and unlocked directly from within the app. The acoustics calculators include Distance to Time, Time to Distance and Sound Pressure Level. The electrical category includes Compare Power and Compare Voltage calculators. There is also a Files calculator for converting sizes of audio files. In addition to a newly designed, streamlined interface and a fully integrated Help feature with examples and instructions, version 2.0 includes a new Time to Samples calculator as well as the addition of a Tap Tempo and number keypad for easy tempo input. Backline Calc 2.0 is now available in the Apple App Store. Audiofile Engineering Website Comments Leave a Reply Cancel reply Your email address will not be published.
