Frequently Asked Questions

NaadSadhana is pushing the limits of hardware, software, technology, artificial intelligence and music which is currently only possible on iOS devices. NaadSadhana does intense real-time processing like music detection AI, synthesizing and simulating sounds for realistic instruments, Raga creativity AI, Taal aesthetics AI, analysing music (notes, raga, phrases, layakari, volume modulation, modality, bandish, mukhada, etc), multitrack recording and mixing, and live in-ear monitoring with effects. To create liveness and responsiveness, the processing, decisions and execution of those decisions has to happen within a few milliseconds.
Unfortunately, Android suffers from high unpredictable latency (20-200 milliseconds) which makes implementing an app like NaadSadhana impossible at the current time.

With version 6 that introduces multitrack recording and mixing, in-ear monitoring and other real-time processing, devices running iOS 12 struggle and this creates a poor experience. iOS 14.2 introduces several software and hardware capabilities in machine learning, neural networks, sound analysis, realtime audio, SwiftUI and more, that make certain features impossible on earlier OS's. 

Sandeep Ranade 'Naadrang' is the creator of NaadSadhana for iOS. He is a software engineer and Hindustani classical vocalist, composer and teacher.

Sandeep Ranade's homepage

NaadYoga (Yoga of Sound) is a highly optimized system of learning and practice created by Sandeep Ranade ‘Naadrang’. It systematically exercises every vocal capabilities needed to produce nuanced and powerful emotion effortlessly in any genre of music. NaadYoga compresses 8+ hours of practice time in 15 minutes.

NaadSadhana for iOS complements NaadYoga very nicely to close the feedback loop during self learning and self practice. (Learn More)

Any devices with the A11 chipset or higher will support video recording.
NaadSadhana already does 24+ tracks of simultaneous playback and recording, and runs 40+ modules of artificial intelligence that analyse music, compute responses on each instrument and then play each sound realistically.  Adding HD video preview and recording in addition to all this heavy lifting is beyond the capabilities of older hardware.
