# react-mirt
An react audio trimmer component ~copied~ inspired by iOS. It can be used to set a start and end time for an audio file in order to process it further, e.g. using ffmpeg. You can also zoom in to make finer adjustments by holding down the handle.
## Install
```bash
yarn add react-mirt
# npm install react-mirt
```
## Use
```javascript
import Mirt from 'react-mirt';
import 'react-mirt/dist/css/react-mirt.css';
function App() {
return ;
}
```

## Styling
There are several ways to customise the appearance. I recommend overwriting the CSS variables. But you can also import the sass file and overwrite its variables or you add your own styles on top.
