# electron-audio-shot
A **completely generic, production-ready npm library** for Electron apps that enables cross-platform audio capture, permission handling, echo cancellation, and screenshot capture capabilities — with full TypeScript and React support.
---
## 🎯 What We've Created
A **universal, drop-in audio + screenshot solution** for any Electron app.
---
## 📦 Features
- ✅ Cross-platform audio capture (macOS, Windows, Linux)
- ✅ Platform-specific permission handling
- ✅ Echo cancellation + real-time processing
- ✅ Screenshot capture (manual + automatic)
- ✅ TypeScript support with full type definitions
- ✅ React components for easy integration
- ✅ Comprehensive testing & docs
- ✅ Zero app-specific dependencies
---
## 🛠️ Installation
```bash
npm install electron-audio-shot
```
> ⚠️ Requires `electron >= 20.0.0` as a peer dependency.

## ⚙️ Quick Start
### Main Process
```ts
import { audioScreenshotService } from 'electron-audio-shot';
const service = new audioScreenshotService({
sampleRate: 24000,
chunkDuration: 0.1,
enableEchoCancellation: true,
});
service.setupIpcHandlers();
```
### Renderer Process
```ts
import { PlatformAudioCapture } from 'electron-audio-shot';
const audioCapture = new PlatformAudioCapture();
await audioCapture.startCapture(5, 'medium'); // Start recording
const result = await audioCapture.stopCapture(); // Stop and retrieve chunks
```
---
## 💻 React Example
```tsx
import { useState } from 'react';
import {
PlatformAudioCapture,
PlatformPermissionChecker
} from 'electron-audio-shot';
export function AudioRecorder() {
const [isRecording, setIsRecording] = useState(false);
const audioCapture = new PlatformAudioCapture();
return (
console.log('Ready')}
onPermissionsError={(err) => console.error(err)}
/>
{
const res = await audioCapture.startCapture(5, 'medium');
if (res.success) setIsRecording(true);
}}>
Start Recording
);
}
```
