★ Activate "Do Not Disturb" mode, if available on your device. No need to invest in electronic shruti boxes anymore. ★ Connect your speaker for rich tambura sound. You can control playback without unlocking your phone or tablet. ★ Wired speakers or headphones work great too. You never need to buy electronic shruti box that costs you a lot of money! Connect your bluetooth speaker or headphone for an immersive tambura sound. ★ Background playback, even without screen ON. ★ Of course, non-stop continuous playback is also possible. So this feature can also help meditators. We also know that soothing tambura sound is used in meditation.

This simplifies keeping track of time for classes and practice sessions. You can play tambura for a specific duration (15 min, 30 min, or 1 hr). Faster tempo will give you denser tambura texture. In slower tempo, individual notes can be heard more clearly. ★ Tempo or speed of the tambura playing cycle can be adjusted. Madhyama shruti (Ma₁ as first swaram) is used in special cases such as playing panchama varja ragams. Panchama shruti (Pa as first swaram) is most widely used. First swaram of the tambura pattern can be either Pa (Panchamam) or Ma₁ (Suddha Madhyamam). ★ Choice of first swarams specific to carnatic music. This is useful to match tambura drone accurately to shruti of instruments which cannot be tuned, such as flute, nadhaswaram, or ghatam. Thus, the app can provide accompaniment to all vocalists, and instrumentalists (violin, veena, mridangam, ghatam, flute, chitravina, etc). That is, 6 Male (Low A) to 7 Female (High B). ★ Full range of kattai/shruti/mane from lowest male shruti to highest female shruti. ★ carnatic terminology: kattai/shruti/mane (1, 1½, etc), swarasthanams (e.g. ★ choice of first swarams which are standard in carnatic music system. ★ tambura playing cycle widely practiced in carnatic music. ★ freq ratios of pure carnatic swarasthanams. ★ good clarity even on phone speakers, budget headphones and earphones. ★ authentic tambura sound (in small app size) This allowed us to craft tambura sound specific for each kattai/shruti/mane, resulting in clear, accurate, and immersive tambura drone across the entire range. With this approach, we get authentic tambura sound.

Instead, Pocket Shruti Box uses a physical model developed by researchers at Sonic Arts Research Center, Queen's University Belfast.


So, compromises will have to be made, ultimately impacting sound quality. To produce good results, many high quality samples of multiple tamburas (of different sizes and tunings) should be recorded, occupying a lot of storage space (potentially in GBs!). Usually shruti box devices and apps merely record a few tambura sounds and pitch-shift them to produce sounds for different shrutis (kattai or mane). Pocket Shruti Box provides high quality Tambura accompaniment for carnatic musicians and students.
