I am working on Noise suppression and cancellation in VoIP media engine. I am looking for noise cancellation & suppression algorithms and its implementation available with real-time low latency algorithms.

I had worked with webRTC noise cancellation implementation and it works well, but I want to explore more on this. I googled this and am not getting any concrete output. I need help from the community and experts to get better an idea of available noise cancellation and suppression algorithms. Below are findings:

Noise cancellation available implementation:

  • WebRTC
  • Speex

Noise cancellation available Algorithm:

  • Least Mean Square Algorithm

finding more on Github is giving lots of results, but needs advise from experts to the way to proceed for choosing Noise cancellation & suppression algorithm for VoIP with low latency.

If you are looking for free open-source ones, the above is the only available list (IMO). Otherwise, there are more advanced options. For example, check out SoliCall's noise reduction software. They offer both PNR (profile-based noise reduction) and RNR (reference-based noise reduction).
