Sir it's a good app but please add other swaras( ri, ga , dha, ni) as well. Also it does not go below C3 but many males tune to A# or B. Please add these features. Otherwise it's a good app.

Thanks for your kind words of appreciation.

The goal of the app is to help tuning carnatic instruments. As all instruments are tuned exclusively to Sa and Pa in Carnatic system, with the rare exception that one string in a Tambura is occasionally tuned to Suddha Madyamam when a Panchama-Varja-ragam is performed, we intentionally kept only Sa, Pa and Ma. This is sufficient to tune any instrument for Carnatic (Please correct if there are any exceptions). Avoiding other notes helped us to keep the interface simple and focussed for tuning purpose. This way the user interface works well even on very small screens.

Having said that, could you elaborate on the need for other swarams for tuning? Do you want the app to detect all the swarams when you are singing/playing, or you want reference sounds for them?
Also it does not go below C3 but many males tune to A# or B. Please add these features. Otherwise it's a good app.
4.5 stars
For low 6½ and 7 shrutis automatic detection works. In fact, automatic swaram detection works for any sthayi in any shruti, from deep bass to ultra high pitched sounds. However, for playing reference sound, we limited the sthayis according to what is audible in typical speakers on mobile phones.

We discussed about your feedback. We realize that it would be useful to provide reference tone for additional lower sthayi for certain kattais/shrutis. Please stay tuned for the updates.

Thank you,
Ananth Pattabi

We have added Anu-Mandra sthayi reference tones for the swarams in all katta/shruti/mane. Check it out on the latest version of Shruti Carnatic Tuner (v1.5.0).

Now 6½ or 7 kattai shrutis can be used for both high female vocal and low male vocal ranges. Thanks for your suggestion.

Thank you,
Ananth Pattabi

Shruti Carnatic Tuner updated! The latest v1.6.0 raises the bar further. Hope you like it.

WHAT'S NEW
★ Ma button is now shown as Ma₁ since it represents Suddha-Madhyamam.
★ New Ma₂ indicator will appear when you play or sing in Prati-Madhyamam range (similar to Ri-Ga and Dha-Ni indicators).
★ Swaram tracker range is reduced to ±60 cents. This improves the clarity for you while tuning.
★ Subtle refinement - When your pitch falls in-between two swaram ranges, Shruti now prefers to show it in Sa, Ma₁, or Pa ranges over their neighbouring swarams. This significantly improves clarity.

Unfortunately, none of them is designed for Carnatic music.

Shruti Carnatic Tuner is the only tuner app specifically designed for Carnatic music on Google play now.
  • It uses Carnatic terminology. Ex: Kattai (1, 1½, etc.), Swaram Names (Sa, Ma1, Pa). It even includes terms used in Tamil, Telugu, Kannada and Malayalam. Other tuners use Western terminology (A, C# etc.). Some use Hindustani terminology, which is nominally better, however carnatic musicians would feel out of place.
  • Fine-tuning of Kattai is done in familiar Carnatic way. In other tuners, you have to struggle with frequency in Hz (changing note A's frequency from 440 Hz)
  • Swarasthana ratios used in this app are proper Carnatic. Other tuners are designed for Western Equal Temperament (ET), which is unsuitable to be used in Carnatic music. Pa in this app is proper 3/2 or 701.955 cents as opposed to 700 cents in ET; Ma1 is 498.044 cents as opposed to 500 cents in ET. The difference is more pronounced in other swarams.
  • It is free and fully functional for tuning purposes. (Only advanced features are available as in-app purchases)
Have no doubt. This is the absolute best tuner app for Carnatic music. If you have used electronic tuners in the market, you will find this app far superior.

Thank you,
Ananth Pattabi

Microtones are not new to Western tuners. Again, done long ago. In fact, they are experimenting with micro tone movements as in gamakas with CarnaticMap features in tuners. Carnatic terminology... give me a break, is that even something to set apart an app feature?

Anyway, happy that Indian music is adapting tuner apps to its own.

Absolutely. I have intentionally mentioned it as the first differentiation over the other features. We want to eliminate the need for carnatic folks having to fumble with western note names and terminology whenever they use modern technology. Usability is a key aspect for us.

In fact, we are considering to have app interface in local languages (kannada, malayalam, tamil, telugu, etc.). We believe it makes a big difference to user experience. We think it is a mistake to assume that all users are just like us.
ramamatya wrote:Microtones are not new to Western tuners.
True. Some western tuners do support microtonal tuning. However, it is never designed for normal usage scenarios, but as an advanced feature (typically paid), targetting enthusiasts who are willing to spend time tinkering with long laundry list of settings to experiment with exotic tunings.

In our system of music, however, microtonality is fundamental. A carnatic student or professional should not be required to know about Just Intonation or Pythogorian Tuning and bend the app just to tune his or her instrument.

Shruti Carnatic Tuner is designed for carnatic tuning. Simply, Sa is Sa and Pa is Pa. No need for any kind of tinkering to get correct carnatic swara sthanas.

---

Thousands of carnatic musicians have found the app useful. Some of them were kind enough to reach out to us with their feedback which helped us to polish and evolve the app.

Please give it a try and let us know if you find it worthwhile.

Thank you,
Ananth Pattabi

I use this app (full features) and have found it to be very helpful for tuning instruments.

Although this is primarily a tuning app, students are also using it to get visual feedback on the accuracy of the notes they are singing. Practicing sustaining notes or kaarvais is also easier with this app for beginners.

I like it that we have Carnatic terminology for the swaras without having to go through the process of translating.

Glad to know that you have discovered this interesting use case to help vocal students.

Great. This is exactly why we stick to carnatic terminology.

Thanks for sharing your experiences. Such feedback gives us plenty of motivation and reassurance that we are doing the right thing. Here are a few other interesting experiences shared through user reviews:
  • "This app actually helped me tune my violin as accurately as my teacher. Helps class start on time as the instrument is already tuned."
    —Saravana Janardhan (on Google Play)

    "Pitch Perfect Helps me check if all my flutes have perfect Sa Pa. Defective ones could be identified and rectified!!"
    —Nandakumar Pachikide (on Google Play)
Thank you,
Ananth Pattabi

The app is tailor made for carnatic. As you see, this thread generated quite some discussion, and the dialog with rasikas actually resulted in improvements in the app. IMHO this thread cannot be shallowly categorized as a mere advert. Still, admins can remove it if this is inappropriate here.

Thank you,
Ananth Pattabi
