FAQ
===
WHY DO YOU NEED MICROPHONE / RECORD AUDIO PERMISSION?
To be able to detect and show you the swarams, the app needs to listen to your singing or playing through your device's microphone. This requires microphone permission, sometimes referred as Record Audio permission.

HOW DO I USE THE APP?
1. Set your kattai / shruti / mane first through the orange circular button.
2. Just sing or play, the app will show you which swaram. If you are close to a swaram, it will indicate below the swaram button. Swaram button will animate once you sing or play that swaram perfectly.
3. If you want to hear, how the swaram sounds like in the selected kattai, tap the swaram button. You can stop it by tapping again.

IS THIS A SHRUTI BOX?
No. For shruti box, checkout Pocket Shruti Box.

I AM SAYING 'Sa', BUT IT IS NOT SHOWING 'Sa'?
This app does pitch recognition; but will not consider the words. So if your singing matches the frequency of Sa swaram, it will show. Of course, first you should set your kattai / shruti / mane correctly.

WHEN I PLAY NOTE C ON MY KEYBOARD, THIS APP DOES NOT SHOW 'Sa'?
Note C on keyboards corresponds to 'Sa' in kattai 1. So first set the kattai to 1, then try. It will work as expected.

WHAT DO YOU MEAN BY "PURE" CARNATIC SWARA STHANAS?
The frequency ratios of Carnatic swarams are different from Western Equal temperament (used in Keyboards and Harmoniums). Shruti Carnatic Tuner is based on authentic frequency ratios of Carnatic music. This is what we mean when we say Pure carnatic swara sthanas.

WHAT HAPPENS WHEN I UNINSTALL AND REINSTALL THE APP OR CHANGE THE PHONE? SHOULD I PURCHASE PREMIUM FEATURES AGAIN?
No. Once you make the purchase, the feature is yours "forever". No need to purchase again. You can uninstall and reinstall the app any number of times. No need to purchase the same feature again. Your purchase will be remembered always. This is true for any purchase.

HOW DO I REPORT A PROBLEM OR PROVIDE FEEDBACK?
You can do it through menu at top right of the app. You can also email to shruti@kuyil.org

Perfect. Initially had a Problem while trying to adjust the sruti of instrument . It seemed , some times it listened to every sound . . even the car and bike on the road, the sound of the rain drops. .. . Now after being used to the app dont have this problem. Guess it was a learning issue about how to use it properly Perfect for that purpose .....Also you can select ur own voice sruti and practice the swara sthaana s using the app, by singing along with each note and perfecting them

Thanks for the update. Your observation is right. We've indeed tested Shruti Carnatic Tuner specifically in noisy surroundings. Once you start singing or playing your instrument, the app should immediately focus on what is important. In case of any issue, just email to shruti@kuyil.org. Thank you.

I used to face a lot of difficulty in tuning my violin and had to always rely on my violin master for tuning. Other tuners in the app market did not work well for me as they seem to be based on Western music. Thanks to this wonderful app I am able to accurately tune violin myself. Not only that, I am now also able to identify the mistakes I make in the swara locations on my violin. Strongly recommend this app for any Carnatic students

We're glad that you recognized the use of Shruti Carnatic Tuner to improve your violin fingering technique. We're also happy to know that your teacher's time during the class is used more productively to teach than on tuning students' violins. We heartily wish you the best for your practice. Thank you for the wonderfully detailed feedback.

Good app. But expected more for the price. They do not have higher/lower notes detector, if it has, found no explanation or any description on the app. Would have been good if we could choose the different instruments while setting the shruthi instead of the annoying the noise set now.

This app detects swarams in any sthayi (higher/lower notes) automatically. It also plays reference sound for swarasthanas in 4 sthayis. This sound is designed to be extremely accurate, clear and neutral, for professional use (to adjust veena melam, flute holes, perfect vocal pitch etc.) Tap on the light bulb in the app to learn about the uses.
