It is compiled by the developers of n-Track one of the main DAW's for Android. That i salso one of the two that have the possibility to hook up an external USB sound card for low latency professional recording as well.
A big reminder to any developers that reads this...
They have developed Audioroute which brings interconnection between apps on Android.
It is free to use so please contact them so we can get the Android music eco system to the next level!!!
Here is what they say regarding their latency tests:
Android devices audio performance chart
This page shows the latency calibration results performed by the n-Track Studio app. Results are collected anonimously.
Although the results are not scientifically accurate as each measurement is performed in different rooms with different acoustic conditions (as well as possibly different device volume settings), the results roughly represet the audio latency performance of various device.
We also show wether or not a device supports the FastPath, which is an optional feature of the Android audio system, which can help minimize audio latency when the app uses the recommended FastPath settings. "base" FastPath should allow for 45ms or lower latency, while "pro" FastPath should enable 20ms or lower latency. In the device detail page, for devices that support the FastPath, you can toggle between showing all results and only results obtained with the recommended FastPath settings.
We hope that this page will help orient users who care about realtime audio and want to identify devices that have good audio performance.
Latencies are measured in milliseconds.
And to see the results with clickable beautiful charts and suchlike:
