SoliCall, for example, is offering innovative wrappers, like SIP, that enable connecting the noise cancellation algorithms into almost any legacy phone system.

So, how can these organizations enjoy the new development in the area of noise cancellation without replacing their entire telecom infrastructure? The answer is to find a way to incorporate a noise cancellation software with their existing legacy phone system. But, most big organization have hard-phones/desk-phones, they can even be expensive trading turret. If you are using a softphone, it is usually easy to connect it to third party noise cancellation software. The software based improvements combine advanced Artificial Intelligence (AI) with improved signal processing algorithms.ĭue to the quick cycles in software development compared to hardware development, at any given point in time the software based solutions will usually have a much better quality than the hardware-based solutions. This approach is now implemented in most high-end phones.
The hardware based improvements are usually using few microphones that work together to identify the background noise and cancel it. We can split them into two categories: hardware based and software based. Now let’s take a closer look at the new developments in the area of noise cancellation. In other words, whatever the technology can give us we are happy to use and we continue requesting for more…. For example we now consume and demand much more bandwidth and CPU than we did just few years ago simply because the technology allows us to do. The same principle applies to any other area in life that is influenced by evolving technology.
The main reason for the increasing demand is the improvement in technology that is now able to provide better quality than the quality that could be provided few years ago and this technology keeps improving every day. For additional reading, take a look at AEC synchronization on Android.The demand for Noise Cancellation in phone calls is constantly increasing. One of products that offer this kind of centralized echo cancellation software is the PBXMate.

In this option, you provide a centralized professional acoustic echo cancellation on behalf of the Android mobile devices. Use a centralized solution for echo cancellation. Use an SDK with a professional AEC filter that has at least all the following capabilities: (a) Quickly recover from synchronization lost between the audio captured from the microphone and the audio rendered to the speakers (b) Can handle an echo tail that might exceed the basic 128ms delay (c) Can be configured to work with different CPU requirements in order to provide enough flexibility during integration.Ģ. There are two options to solve this problem:ġ. Moreover, the shortage in CPU power might also lead to an increase in echo tail/delay that can quickly reach few hundred ms. Since Android devices are run on many brands of CPU and hardware platforms, in different cases the CPU is simply not powerful enough to simultaneously run all the applications and in addition to do a proper acoustic echo cancellation. Since the former audio stream is used as a reference to cancel echo from the latter audio stream, unsynchronized audio streams forces the AEC to operate in a volatile environment. In other words, it is hard to synchronize the audio packets that are being sent to the speakers with the audio packets that are being captured by the microphone. On Android’s audio system it is harder to synchronize both sides of the audio. In this post we will review the main reasons and alternative solutions.

In addition, it turns out that for Android devices this task is even harder. As discussed in few of our previous posts on echo cancellation, in real-life conditions performing a good echo cancellation is a rather complex task. One of the areas with an increasing demand is the need to solve echo issues with Android devices.
SoliCall offers different software solutions for audio quality improvements.
