We mentioned at the beginning that the data format also affects Bluetooth latency. Note that Bluetooth receiver should support aptX too. So in order to get total low latency, the device should be fast enough (or be Samsung Professional Audio enabled) and support aptX codec.

Here is the information about aptX latency. Here is the list of devices that support aptX. Such good values for Bluetooth latency are due to the fact that this device supports low-latency Bluetooth codec aptX. The best result is for HTC One M7 with the ViMicRowX Bluetooth receiver: 330 - 290 = 40 ms, however round-trip for this device is too high (290 ms). We get it by subtracting latency measured with the connected Bluetooth receiver and round-trip latency. It seems that a lot of Samsung devices support this technology.Īnother thing that influences the total audio latency is Bluetooth latency. Note that Samsung devices at the top of this list use Samsung Professional Audio SDK, which is intended for low-latency audio. Yet another set of statistics shows that it is possible to get much better results: for example 18 ms using LG G4 (LGE LG-F500L), and 15 ms using Samsung Galaxy S5 (Samsung SM-G900H).

Here is some statistics by Google which show that the best result for Nexus 9 with Android 5.1.1 is 32 ms. I believe that it is possible to achieve better results using the low-level OpenSL ES. The minimum value is 100 ms, which is not so good. It is shown in the No Bluetooth column (see the table below). If we cut off the Bluetooth receiver and connect the Speaker directly to the Android device, we will obtain round-trip latency.

Measuring the distance between two knocks in the audio editing software will give the total latency:

In order to calculate the latency we pair the Android device with the Bluetooth receiver, run this application on Android device, run an audio recording application on the PC ( Audacity) with the stereo microphones connected, and just knock on the table near the microphone on the Android deviceĪs a result, the PC will record two knocks: the original one and yet another one that passed all processing path. Here, a special Android application performs recording and an immediate playback as fast as possible using the standard Java methods. The following picture illustrates how the application works and how the testing is performed: Round-trip audio latency is the time between capturing audio data, performing data zero processing in the application and playing the data. Let’s imagine the following scenario: we need an application that captures a microphone and passes audio data to the output through the Bluetooth speaker.Īudio latency, in this case, depends on two things:

Also, my circle thingies tend to break trying to draw this many pings.For providing extended functionality to your users, check How to Add Video Calling to Your App Easily (Quickblox SDK Overview). You can always run multiple tests if you need to. I'm not exactly made of money for hosting here, and I really doubt you need this intense of testing. Uh, sorry, but and is a bit too intense of testing. This will send a total of 149 ping s and use 15.4 KB of data. Or Select a Preset Approximation: Wait 2 seconds before recording results?

Now, you can just hit "Start Test" below, and then interpret your results.Īlso, you can read a bit more about the site at the dedicated About and Technology pages. This makes it very easy for anyone to test their packet loss (also known as "packet drop") without downloading a more complicated tool like iPerf. I could not find another site that has implemented this type of test, so I made one. Recently however, WebRTC has been added to modern browsers, finally enabling this type of test. Up until recently, web browsers have not been able to test this, as they have always retried everything until it works. These programs also do not usually resend information if it fails to get there, so if packets get lost in transmission, they are gone for good, which can also have a significant impact. Speed is important for general Internet browsing, downloading files, and video streaming, but it is not a very good measure for performance for more communicative activities.Īctivities like gaming and voice chat usually do not need much raw bandwidth, but they need prompt and reliable responses. This complements a traditional speed test, which only measures the raw speed and latency. These problems can all be caused by various similar issues, which hopefully you will be able to find and fix using this easy way to test for them.
