Since we use the speaker and the microphone for the test, tap "OK" to allow access to the microphone. When the installation is completed, the icon named "Latency Test" is displayed on the desktop, so tap and tap "trust" further. Those who are concerned about security will be responsible at your own risk. If you tap "Install", the application will be installed directly without going through iTunes or Google Play. You can install it from the bottom of the page in the same way. This time I use iPad to measure latency so I tapped "iOS". To install the app, visit the site above on a smartphone or tablet and tap "Android" or "iOS" at the top of the page. The application installation and the actual measurement method are as follows. In a game or professional world where the delay of a few seconds is the death, this is a numerical value that it will be a very big handicap.Īs described above, the actual condition of the latency has considerable difference depending on the model, but users who have iOS and Android terminal can also check the status of their own terminal by installing a dedicated application. That latency is 451 milliseconds, which means that it sounds about 0.5 seconds behind the operation in brief. Such rankings are described over 70 models, but what was listed at the bottom of the ranking is " Acer Iconia A1-810"was. Both sample rates are 48000 Hz (48 kHz) and the buffer size is 64. The first place "iPad Air (first model) + USB audio" means that the state using the iPad Air body and USB audio has the best result, its latency is 6 msec good. It is a surprising result that Apple products monopolize from 1st place to 10th place. Result ranking for each terminal measured by Audio Latency Test App is. If too much latency is increased, a sense of incompatibility of "delay" which is felt when operating the equipment will occur, which will adversely affect the feeling of operation and comfort.Įspecially for games and movies where quick response is required, and for severe professional sites " 10 milliseconds is the limitAlthough it is a latency which is sometimes said to be said, what is the measurement result for each terminal? An application that can measure such latency is " Audio Latency Test AppSo, more than 70 kinds of devices ranking using this is announced.įor devices handling digital audio, the delay due to the conversion process between analog and digital signals and the internal calculation always occurs, and this is called latency. In addition to smartphones and tablets, the device handling digital audio signals is more or less certainly a signal delay called "latency" is always occurring. 12:09:08 "Audio latency" performance ranking of smartphones and tablets and measurement method that can be done by oneself
