The demand for Noise Cancellation in phone calls is constantly increasing. 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. The same principle applies to any other area in life that is influenced by evolving technology. 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. In other words, whatever the technology can give us we are happy to use and we continue requesting for more….

Now let’s take a closer look at the new developments in the area of noise cancellation. We can split them into two categories: hardware based and software based. The hardware based improvements are usually using few microphones that work together to identify the background noise and cancel it. This approach is now implemented in most high-end phones. The software based improvements combine advanced Artificial Intelligence (AI) with improved signal processing algorithms.

Due 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.

If you are using a softphone, it is usually easy to connect it to third party noise cancellation software. But, most big organization have hard-phones/desk-phones, they can even be expensive trading turret. 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. SoliCall, for example, is offering innovative wrappers, like SIP, that enable connecting the noise cancellation algorithms into almost any legacy phone system.

In addition to connectivity, one more aspect that should be considered is CPU demand by the noise cancellation software. Since the noise cancellation software will do audio processing on behalf of all the hard-phones, one should make sure this processing has relatively modest CPU requirements so you will not find it burning the CPU.
