A few days ago, I got a mail from Dan Galpin as an answer to my previous blog entry
The audio latency of the new Nexus 7 (2013) is not 40ms!. He mentioned this tip:
„Also, always measure latency through the headphone jack, because it’s quite common to have to postprocess audio for the (poor-quality) speakers in devices.“
OK, time for some additional measurements. I also used this opportunity to check some possible optimizations to my apps that could improve latency. Those optimizations are not part of the official releases so far and since they implicate larger changes, they probably will not for some time. However, the measurements show what can be achieved. I also added values for an Acer A500 as example of a „third-level device“.
