SrutiBox simulates an Indian harmonium, used as a base tone in Indian music and in spiritual practices of chanting and droning.
SrutiBox 1.4 now works under iOS8, iPhone 4,5,6, and 6+ sizes, has a slightly different look, and fixes a few bugs that you may have encountered.
SrutiBox is a synthesizer, creating drones with various timbres and precise intonations that blur the distinction between tones, timbres and chords. The drone can be fairly static or undergo slow modulation and harmonic change. It now plays in the background under iOS 4.0 like many other music apps!

"I wanted you to know that I have made my debut in Vienna a couple of weeks ago as an iPHONEist.
I played two simultaneously - one with sruti box and the other with a variety of apps.
I am enjoying sruti box immensely! Thank you!"
— Dr. Pauline Oliveros
I also have another Droning app, Droneo, which has a similar interface, but more droning options!
SrutiBox uses 12 "reeds" which can be tuned to a great number of scales, randomly detuned, and chorused and modulated. The pitch interval and volume of each "reed" can be set individually, making for a wide variety of drones. The reeds can be set to various timbres suitable for drones, including vocal-like timbres and low frequency-friendly chirps.
A special iPhone feature of SrutiBox is that you can wave the phone in an imitation of pumping the bellows, adding a touch of realism to the simulation.
SrutiBox can also be used as a pitch source for instrument tuning purposes, or as an aid for learning the difference between Just and Equal Tempered intervals.
As with other iPhone/iPod touch audio applications, itll sound better through headphones, although in a quiet room, its quite effective! Make sure to use the volume controls on the side of the phone to set the volume level you like.
