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.
