Measure the performance of any mobile device immediately with the Superpowered Mobile Audio Latency Test App for Android and iOS.
Low round-trip audio latency is a strong indicator of how well any mobile device is optimized for professional audio. Lower latency confers significant benefits to users of all sorts of apps like games, augmented hearing apps, VOIP and other interactive apps.
The application does not collect any personal or business data, just the device model, operating system version, audio latency, sample rate and buffer size.
Notes on Latency Measurement
The Superpowered iOS and Android Audio Latency Test App measures the theoretical lowest roundtrip audio latency possible on a device. Roundtrip latency is measured from device microphone (audio input) to device speaker (audio output). Results may therefore vary if external accessories such as a microphone or an active speaker are connected to the device.
Digital instruments begin to feel "natural" with roundtrip audio latency under 10 milliseconds. 10 ms roundtrip audio latency is the target value for professional audio applications.
Latest iOS models from the first iPad have slightly different built-in microphone input handling. The default audio session mode adds around 30 ms of additional latency due some feedback reduction and other pre-processing. Use the "measurement" audio session mode for minimum round-trip latency with the built-in microphone input on iOS.
Samsung Professional Audio SDK is supported from Android 5.0 (Lollipop).
The app follows Google's low latency audio recommendations. Some poorly built/configured Android devices may not output audio at all.
