Immersitech Engage™ Core SDK


The Immersitech SDK is a C / C++ library that allow you to easily augment your existing audio applications with several audio effects, including noise cancellation, 3D spatial audio, and voice clarity effects. Provide the library with an input audio buffer and the library will output an audio buffer with the enhanced audio.

System Components


Noise Cancellation

Using Machine Learning, the Immersitech Engage™ Core platform is trained to remove over 52,000, 48 kHz sounds that take away from providing an engaging digital experience. From dogs barking to the constant hum of an air conditioner,  you’re covered. During AI model training, we perform a real-time combination of noise, clean speech, and impulse response data to create optimum coverage for noise cancellation. For special use cases, we can work with you to customize the model to remove specific types of noise.

Voice Clarity

Tightly coupled with Noise Cancellation, Voice Clarity enhances the quality of participant voices to ensure that all participants sound natural, clear, and crisp – not over-processed. We provide audio gain control to put loud and quiet talkers on a common level, and even equalize the tonal qualities of the audio stream to provide a more consistent and understandable voice character.

3D Spatial Audio

Using patented audio processing techniques, we can place each participant at distinct location within 3D space around the listener. The placement of participants in 3D space allows for a more natural, realistic experience that reduces digital meeting fatigue that many experience in traditional online meetings. Listeners can use headphones or a single pair of speakers to experience the 3D spatial effects.

How it works

Example: Processing audio for 3 person conference


  • Participants can have multiple input, output, and metadata streams that are processed and mixed using low-latency methods to maintain a high-quality experience.
  • Positional data gives Service Providers an opportunity to create immersive experiences by sending real-time positional data or defining targeted user positions depending on your desired use case.
  • Developers and Service Providers can configure the Immersitech Engage™ Core in various combinations of the 3 primary features using a simplified set of APIs.

Implementation Options

Client Side Implementation


  • The SDK is deployed as part of your compiled application.
  • Noise Cancellation and Voice Clarity can be deployed quickly without external dependency.
  • 3D Spatial Audio can be enabled using real-time coordinate information to render sounds in specific locations.

Hybrid Implementation


  • The SDK installed on the client-side handles Noise Cancellation and Voice Clarity.
  • A central server-based solution handles 3D Spatial Audio.
  • The processing power is split between the server and application, ensuring less strain on your participant’s machines.

Server/Cloud Implementation


  • The SDK is connected to server application via a platform-specific adapter.
  • Engage Core will receive audio from all connected clients and send processed streams back through server application.
  • With coordinate information, 3D Spatial Audio can render sounds in real-time in specific locations.
