- Android 10ms Problem? Solved. June 2016 Overview, Results & Demo
- Many types of mobile apps that are dependent on low latency audio functionality are non- existent on Android. Meanwhile on iOS, these same apps generate $$$ and thrive.
- Definition of round-trip low latency is: + Audio Input (time) + Audio Processing (time) + Audio Output (time) = 10 milliseconds or less iOS has been low latency since Day 1.
- Apps suffering from lack of low latency audio include games, synthesizers, DAWs, interactive audio-, pro audio-, virtual instrument apps, and the inevitable gold rush of virtual reality apps.
- No low latency audio support in Android? Effectively guarantees that there will be no adoption of VR on Android.
- Without low latency audio support, developers cannot meet demand, Android app marketplaces miss out downloads, OEM devices less valuable and consumers frustrated. Entire Android ecosystem loses.
- Developers. Android App Stores. OEMs. Consumers. Billions left on the table.
- Not trivial technical problem. Multiple non-obvious technical hurdles and coordination issues within Android ecosystem. Not to mention, thankless work fixing a problem most donât know even exists. Yet big problem, big upside.

- Industry Misconceptions of Android 10ms Problem âItâs a hardware problem.â âItâs Linux audio.â âItâs the ALSA drivers.â In our opinion: Theyâre all fine.
- Superpowered. Who are we? We squeeze audio latency out of app user-space with +150m app- installs and thousands of apps using Superpowered SDK. Now, weâre squeezing audio latency out of Android service space with Superpowered Media Server.
