+## Latency detection
+In order to get an idea of the output latency on your device, you can start with detecting the [round-trip latency](https://source.android.com/devices/audio/latency_measurements#measurements), (ie. the input latency + app processing time + output latency). When switching on the round-trip detection button, the app will attempt to detect the time elapsed between the moment a click is written to an output buffer, and when it is detected in an input buffer. At this point the click detection is *extremely* crude, but it seems to work if you run it in a quiet environment (without a headset plugged in). In [this thread](https://github.com/google/oboe/issues/80), it is suggested that the output latency is the round-trip latency minus 3ms. However on the couple of devices I tested the detection, it seems that setting the latency to half the detected round-trip value and adding ~10 ms gives a good result for Link synchronisation. This is still pretty hacky and not very user friendly I'm afraid.
 
 ## Purpose of this repo
 Serve as spring board code for Android audio apps needing Ableton Link support. Similar to the LinkHut app on iOS.

 I'm putting this code out hoping that you smart people out there can help improving it. I'm trying to keep the API level somewhat low (currently 19).
 
 Contributions on the following are especially welcome:
-- Latency calculation: how can the latency be set automatically? It seems there's some effort from the Oboe team for implementing this, but I'm not sure how to implement that for low API levels. Is it even possible?

 - Link Session info: implement some C++ to Java callback to present alerts to the user when the peers count changes (like on iOS implementation).
