# audio-extractor
This project demonstrates client-side audio extraction from video files using two different strategies:
- FFmpeg (via WebAssembly)
- AudioContext API (currently a placeholder implementation)
## features
Select an extraction strategy.
Upload a video file.
Extract audio using the selected strategy.
Play the extracted audio directly in the browser.
## technologies used
- React: For the UI and handling state.
- FFmpeg.wasm: For video processing in the browser.
- TypeScript: For type safety.
## installation
Clone the repository:
```bash
git clone
cd
```
Install dependencies:
```bash
npm install
```
Start the development server:
```bash
npm run dev
```
## how it works
FFmpeg Strategy
Loads FFmpeg.wasm and its dependencies.
Reads the uploaded video file and writes it to a virtual filesystem.
Runs an FFmpeg command to extract the audio stream (-vn -acodec copy).
Converts the extracted audio to a Blob and generates a playback URL.
AudioContext Strategy (To Be Implemented)
Currently, the AudioContext strategy is a placeholder and does not process audio yet.
## usage
Choose an extraction strategy (default: FFmpeg).
Upload a video file.
The extraction process starts, and the extracted audio appears as a playable element.
## future improvements
Implement the AudioContext strategy for in-browser audio extraction.
Support more output audio formats (MP3, WAV, etc.).
Improve error handling and UI feedback.
