Example Usage

import * as React from 'react';

import {
  Button,
  Dimensions,
  StyleSheet,
  Text,
  ToastAndroid,
  View,
} from 'react-native';
import {
  type ConvertAudioOptions,
  convertAudio,
  AUDIO_OUTPUT_FORMAT,
} from 'rnvideoeditor';

const ConvertAudio = () => {
  const convertAsync = async () => {
    try {
      const options: ConvertAudioOptions = {
        audioFileUrl:
          'file:///storage/emulated/0/Android/data/com.rnvideoeditorexample/cache/RNVideoEditor_audio_converted.aac',
        outputFormat: AUDIO_OUTPUT_FORMAT.AUDIO_MP3,
      };
      const startProcessing = performance.now();
      const uri = await convertAudio(options);
      const endProcessing = performance.now();
      ToastAndroid.show(
        `Audio Converted in ${millisecondsToSeconds(
          endProcessing - startProcessing
        ).toFixed(3)} s`,
        ToastAndroid.SHORT
      );
      console.log(uri);
    } catch (error) {
      console.log(error);
    }
  };
  return (
    <View style={[styles.box]}>
      <Text>Convert Audio </Text>
      <Button title="Convert Audio" onPress={convertAsync} />
    </View>
  );
};

const styles = StyleSheet.create({
  box: {
    width: Dimensions.get('window').width - 100,
