What is the best way to store an audio Blob in the repository file system?

Currently, I have set up a system to record user audio through the device's microphone and can successfully download it on the same device. However, my goal now is to store this audio in my database by making an API call. How can I efficiently send this audio blob to the backend? The sample code provided saves the audio file to the downloads folder on the recording device.

const addAudioElement = (blob: any) => {
    const url = URL.createObjectURL(blob);
    const a = document.createElement("a");
    a.download = "file name";
    a.href = url;
    a.click();
    window.URL.revokeObjectURL(url);
};

Answer №1

If you wish to store this in the database:

Start by creating an object instance using the File built-in API

const audioFile = new File([AudioBLOB], "file.mp3", {
    type: "audio/mpeg",
});

Next, include the file in FormData

const formData = new FormData();
formData.append("audio", audioFile);

Finally, send the formData using axios/fetch to the backend

await axios.post(endPoint,formData,{ "content-type": "multipart/form-data"});

For the backend, if you are working with node.js or next.js API, you can utilize a library like multer

Using multer, you can handle the uploaded audio on the backend and save it to your database
