## Installation

Integrate our SDK into your Node.js application with our native bindings.

```bash theme={null}
npm install @ai-coustics/aic-sdk
```

## Quickstart

```javascript theme={null}
const { Model, Processor } = require("@ai-coustics/aic-sdk");

// Get your license key from the environment variable
const licenseKey = process.env.AIC_SDK_LICENSE;

// Download and load a model (or download manually at https://artifacts.ai-coustics.io/)
const modelPath = Model.download("quail-vf-2.1-l-16khz", "./models");
const model = Model.fromFile(modelPath);

// Get optimal configuration
const sampleRate = model.getOptimalSampleRate();
const numFrames = model.getOptimalNumFrames(sampleRate);
const numChannels = 2;

// Create and initialize processor
const processor = new Processor(model, licenseKey);
processor.initialize(sampleRate, numChannels, numFrames, false);

// Process audio (Float32Array, interleaved: [L0, R0, L1, R1, ...])
const audioBuffer = new Float32Array(numChannels * numFrames);
processor.processInterleaved(audioBuffer);
```
