Determine Mime-Type - Audio

import fs from "fs";

export default defineComponent({

async run({ steps, $ }) {

// adjust filePath to your own use-case.

const filePath = steps.download_audio_to_tmp.$return_value.filePath;

try {

// Read the downloaded file

const fileBuffer = await fs.promises.readFile(filePath);

const mimeType = mime.lookup(filePath);

// List of known audio MIME types

const audioMimeTypes = [

} catch (error) {

$.export('error', error);

throw new Error(`Failed to detect the MIME type of the file: ${error.message}`);

}
