iOS echo cancellation in Unity

How to use the NatDevice plugin to implement iOS echo cancellation in Unity.

Prerequisites

• Unity 2020.3+

• NatML cloud access key (https://docs.natml.ai/unity/#get-natml)

Instructions

• Add the following items to your Unity project's Packages/manifest.json

 { 
   "scopedRegistries": [
    {
      "name": "NatML",
      "url": "https://registry.npmjs.com",
      "scopes": ["ai.natml"]
    }
  ],
  "dependencies": {
    "ai.natml.natdevice": "1.2.2"
  }
}

• Copy your access key and add it to your Project Settings:

• Copy NatDeviceAudioSource.cs from the liveswitch demo project located at Assets/Scripts/Channel
• Change the CreateAudioSource method in LocalMedia.cs to return NatDeviceAudioSource instead of AudioClipSource

  protected override AudioSource CreateAudioSource(AudioConfig config)
    {
        return new NatDeviceAudioSource(config);
    }
