Marshmallow improves audio latency here and there on some devices, but even Android N has the fundamental audio stack problems we mention in the articles.

There is no Android version delivering <= 10 ms round-trip audio latency.

Audio can be handled by built-in hardware or external (USB) hardware.

External: Android is not able to deliver glitch-free low latency audio on USB devices. We introduced a solution for this last month, that's one of the links on the top of the article. It opens up a market of 1.1 billion devices (meaning, Android 4.4.4 and up) for USB audio on Android.

Built-in: The current article introduces a demo solution for the built-in audio hardware.
