A lot of smartphones face the issue of audio latency while playing video. For people who do not know what audio latency is, it is that delay of audio you experience on your phone while running an application. For example, while watching a movie on your phone you might hear the sound coming slightly later than the picture; or while using a music creation application, sound might be delivered later than when the app starts playing it.
The latency issue is one that advanced operating systems for smartphones should not have. Nonetheless, Android has it and it has bothered countless Android phone owners. The latest version of the OS, 4.1 aka Jelly Bean, exhibits a sound delay of nearly 48 milliseconds. This is quite noticeable for people who have large screen Android phones and watch movies on it. The time is definitely an improvement over the previous delay of 88 milliseconds, yet there is much room for improvement.
Fortunately, Android is an OS for which there is a huge active community of hackers and modders. These programming experts work tirelessly to solve the little problems in the OS and improve it in every possible way.
The sound delay has been tackled by a hacker with the pseudonym “vonVideo.” The hacker is a part of the XDA Developers forums and has created a fix that brings the latency down to 18 milliseconds – a dramatic improvement over the original settings.
Apart from regular Android users, Android developers should check out this fix. It is currently in its beta and could give developers good ideas on how to reduce the sound delay even further.
