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, it'll sound better through headphones, although in a quiet room, it's quite effective! Make sure to use the volume controls on the side of the phone to set the volume level you like.

This app has been updated by Apple to use the latest Apple signing certificate.
Updated for IOS8 (and iOS7!), and also for iPhone 4, 5,6 and 6+!
With a new, flatter look, same old SrutiBox inside though.

Great app, but I need some help testing something
Is the new version causing anyone else's iPhone to overheat and stay overheated until the app is uninstalled? I had this installed for a couple days before I tried it. After trying it, I didnt notice anything odd, but a few hours later my iPhone felt really warm. I thought it was a body heat thing, since the phone was kept in an inside coat pocket. But the temp never dropped, even when I kept the device off-charger and near a fan.
At some point I recalled that v1.0 of Sruti mentioned slight heating while Scrutibox was played...I guessed that maybe some function in version 1.1 wasn't releasing all of its resources, and this was causing some sort of runaway heating...to test this, I uninstalled Srutibox. I noticed almost instantly that my iPhones temp was normal.
Has anyone else experienced this?
This is not a knock on the app at all...I really enjoy it and wish I could find a way to port the sound to my Boss BR-600...but I can't play it if it's going to overheat my phone.
great app...a must have
this app has been good since 2008 but the 2014 iOS 8 updates rock! the app sounds great, looks great and it worth its weight in bytes.
get this app today!!
p.s., i gave the app 5 stars despite it missing audiobus support; my stars are freely given, without expectation of audiobus delivery later on. i would, however, pay for audiobus support.
Thank you for your huge effort to update this greet app!
With Family Sharing set up, up to six family members can use this app.
