## What is Shruti Box?

The shruti box is a small instrument with reeds, used to play a drone in music. Imagine an harmonium or accordeon without any buttons.

You just select a set of notes, and the shruti will play them together continuously. The main purpose is to create a musical atmosphere to sustain the solist with its voice or musical instrument.

The Shruti box is usually used in karnatak or hindustani music in India.

You can create different musical atmosphere with the three different sound flavours of our Shruti box:
- Traditional Harmonium sound, with deep sound of original reeds
- Light shruti sound, which provides a clearer sound
- Modern flute organ, simpler, heavenly

If you're interested to play indian music (karnatac or hindusthani), this is the perfect "travel" shruti box you need. Tune your shruti in the indian harmonic scale. You select harmonic scale, and the base note. That's it. 

If you prefer to play western music and you need a tempered chord, then tune the shruti to the common tempered scale.

Our shruti box can do automatic transposition. You can configure it in any key with the same keyboard position. You just need to select the note to play on the C key of the keyboard.

You can play up to 4 notes together (with or without octaves). It will produce a sound of high quality, much better than all the electronic devices you can buy for playing shruti.

For getting the best sound from this instrument, it is advised to use a good headphone or a pair of speakers with loudspeaker.

### 1/5 — Sounds nothing like a shruti box

*2025-12-30, version 4.2*

Just sounds like an 80s new wave ooooh voice synth you’d hear from Depeche Mode or OMD.

### 5/5 — It Actually Works Great!

*2023-04-17, version 4.2*

Those who dislike it simply don’t understand it. It works perfectly and has beautiful “voice” selections. The virtual Shruti box can be “pumped” by moving the volume slider up and down with one finger - actually easier than a “real” Shruti box.

### 1/5 — Don’t bother...

*2022-06-19, version 4.0*

...not worth the space on your device.

### 1/5 — Lousy sound

*2021-05-31, version 4.0*

Doesn’t sound even remotely like a Shruti Box

### 5/5 — Absolutely brilliant!

*2019-04-14, version 4.0*

Strongly recommended for practice with any wind instrument.

### 1/5 — Bad app

*2019-03-21*

Third class app,don’t buy.It should not be included in app store

### 1/5 — Didnt like it

*2018-12-07, version 4.0*

Please need a refund sent an email to u quality is poor

### 1/5 — No sound on iPhone 6s

*2017-10-23, version 4.0*

Will not produce any sound on my iPhone 6s.  I had to download  a free software after forking out money for this app.

### 1/5 — update doesn't work... no sound

*2017-07-29, version 4.0*

and crashes as a bonus

### 5/5 — Great sounding Shruti box.

*2017-07-28, version 4.0*

Very welcome update, but still needs Audiobus or IAA compatibility. The lack of these options limits its use. 
Please add!
