Android Tablet Devices for Music
Latency is essential for music apps. For an app to feel expressive, it requires a quick response from touch or input to resultant sound. The iOS SDK has served this niche well and recently Android has started improving their audio latency.
Only a limited range of Android tablets are capable of these low latency response times. The only way to figure out which devices support these lower latencies is to submit dummy builds to the google play store and see what registered devices appear as compatible. Even then support isn’t guaranteed.
This list is current as of Feb 20,2018
Android Audio Pro Devices
android.hardware.audio.pro indicates a continuous round-trip latency of 20 ms or less.
- HTC: Nexus 9, 9 LTE
- NVIDIA: Shield Tablet
- Sony: Xperia Z4 Tablet
Unfortunately, these devices are all discontinued.
Android Audio Low Latency Devices
android.hardware.audio.lowlatency indicates a continuous output latency of 45 ms or less.
I also tried this flag, to see if it perhaps would turn up more devices. Unfortunately the list is the same.
Here’s a sample
AndroidManifest.xml for anyone curious in running their own reports:
<!--<uses-feature android:required="true" android:name="android.hardware.audio.pro" />-->
<uses-feature android:required="true" android:name="android.hardware.audio.low_latency" />
I ran this with
If you’re curious, here’s a Google report of round trip latency on some older devices.
