SrutiBox is a unique synthesizer app that simulates the Indian harmonium, which is widely used as a base tone in Indian music and spiritual practices. The app is developed by Henry Lowengard and available for iPhone users in the multimedia category. It offers a precise intonation that blurs the distinction between tones, timbres, and chords, creating drones with various timbres and allowing the reeds to be tuned to a great number of scales, randomly detuned, and chorused and modulated.

The app has a slightly different look and fixes a few bugs that may have been encountered in the previous version. It also plays in the background under iOS 4.0 like many other music apps. Additionally, SrutiBox can be used as a pitch source for instrument tuning purposes or as an aid for learning the difference between Just and Equal Tempered intervals. The app is effective in a quiet room but sounds better through headphones.

SrutiBox offers a touch of realism with a special iPhone feature that allows you to wave the phone in an imitation of pumping the bellows. It is highly recommended for Indian music lovers and spiritual practices enthusiasts. Visit the SrutiBox web pages for more information, hints, support, and advice.
