need help again
I use Webpack and I have audio file, this is how I load it:
const file = require('@/assets/filename.mp3')
const blob = new Blob(file) // it doesn't work
Now I need to get Blob from it.. I can't understand how to do that.
And the final goal is to get audioBuffer
Thank you for any answers 🙏
Use the Fetch API to request the file from the server. Then read it as an ArrayBuffer and decode it to an AudioBuffer by using the BaseAudioContext.decodeAudioData() method.
/**
* Get a file, read it as an ArrayBuffer and decode it an AudioBuffer.
* @param {string} file
* @returns {Promise<AudioBuffer>}
*/
const fetchAudioBuffer = async file => {
const audioContext = new AudioContext();
try {
const response = await fetch(file);
const arrayBuffer = await response.arrayBuffer();
return audioContext.decodeAudioData(arrayBuffer);
} catch (error) {
console.error(error);
}
};
// Fetch the file and decode it as an AudioBuffer.
fetchAudioBuffer('path/to/assets/filename.mp3').then(audioBuffer => {
// Use your audioBuffer here.
});
