IRIS Web SDK

Install

Set your IRIS token

export IRIS_SDK_TOKEN=<INSERT YOUR TOKEN HERE>

Install the IRIS Web SDK

npm install https://sdk.iris.audio/assets/iris-web-sdk/1.2.5/irisaudiotechnologies-iris-web-sdk-1.2.5.tgz\?token\=$IRIS_SDK_TOKEN

Licensing

Make sure you have obtained a valid licence and key.

Do your best to keep the licence and key safe. We recommend fetching them from a server after a user has logged in.

Do not publish these files to the public.

Setup

Before you use the SDK there needs to be a small amount of setup. Unlike other implementations of the IRIS SDK, when running on the web we need to load certain js files at runtime in accordance with this pattern. This means that these files need to be accessible from the frontend and should live in the public directory.

The steps are summarised below but we also have a script to make it simpler.

Setup Wizard

The simplest way to get up-and-running in your frontend projects is to use our Setup Wizard. If you have installed with NPM you should be able to call the following:

npx @irisaudiotechnologies/iris-web-sdk setup-wizard

Alternatively, the wizard can be found in the scripts directory of the installed package. Usually: ./node_modules/@irisaudiotechnologies/iris-web-sdk/dist/scripts/setup-wizard.mjs

Manual setup

Move the iris-awp directory from the installed dir (usually ./node_modules/@irisaudiotechnologies/iris-web-sdk/iris-awp to the public folder. The files in this directory need to be accessible from the frontend at runtime. It follows this pattern
```
mv ./node_modules/@irisaudiotechnologies/iris-web-sdk/dist/iris-awp ./public/iris-awp
```

Download the core SDK using the following command.

curl -O https://sdk.iris.audio/assets/js/iris-sdk-1.2.5.tgz?token=$IRIS_SDK_TOKEN

Unzip the downloaded tarball.
```
tar -xvzf iris-sdk-*.tgz
```
Move the unzipped folder package to the iris-awp dir, renaming it to iris-sdk-wasm, e.g. ./public/iris-awp/iris-sdk-wasm.
```
mv ./package ./public/iris-awp/iris-sdk-wasm
```

The resulting file tree should look like this:

public/
└── iris-awp/
    ├── iris-awp.js
    ├── iris-base-awp.js
    ├── iris-sdk-wasm/
    │   └── dist/
    └── utils/

Usage

Step 1: Create new instance of the sdk with minimal config

const config = {
  audioWorkletPath: 'PATH/TO/iris-awp/iris-awp.js', // REQUIRED
  company: '<COMPANY_ID>', // REQUIRED
  key: '<IRIS_SDK_KEY>', // REQUIRED
  license: '<IRIS_SDK_LICENCE>', // REQUIRED
  team: '<TEAM_ID>', // REQUIRED
  user: '<USER_ID>', // REQUIRED
  model: 'clarity',
};

const iris = new IrisSetup(config);

Step 2: Initialise IRIS with an Audio Context

This has to be done with a click event, usually at login.

const audioCtx = new AudioContext();
await iris.init(audioCtx);

Step 3: Connect local stream (microphone) to IRIS

iris.connectSendStream returns a new MediaStream which you can connect anywhere.

const processedLocalStream = iris.connectSendStream(localStream);

Step 4: Connect remote stream (speaker) to IRIS

iris.connectReceiveStream returns a new MediaStream which you can connect anywhere.

const processedRemoteStream = iris.connectReceiveStream(remoteStream);

Step 5: Wait for activation

The IRIS Web SDK is initialised asynchronously in the audio worklet thread. We have two ways to know when it has succeeded.

Set a callback function.

iris.options.onReady = () => {
  // Do something here
  console.log('iris activated');
};

Set up an event listener.

document.addEventListener(
  'iris-activated',
  (event: CustomEvent<IrisActiveEvent>) => {
    const { irisLoaded } = event.detail;
    if (irisLoaded) {
      // Do something here
      console.log('iris activated');
    }
  }
);

Step 6: Start call

iris.start();

Step 7: Toggle between IRIS on/off states

0 = IRIS processing OFF
1 = IRIS processing ON

iris.crossFade(1, 'send'); // turn processing on for the send (mic) stream
iris.crossFade(0, 'receive'); // turn processing on for the receive (speaker) stream

Step 6: Change the mix (wet/dry) level

0 = Allow all sounds through (equivalent of processing OFF).
1 = Allow only voice through (equivalent of processing ON).

iris.setMixLevelMic(0.5); // mic
iris.setMixLevelSpeaker(0.5); // speaker

Step 7: Hangup

iris.stop();
