Load locally saved files to tonejs

I am trying to create an app with the electron-react boilerplate where i can create audio files.

I found Tone.js, which allows me to play sounds but loading the sample files seems close to impossible. Is there a way to give the audio data to Tone?

I am using Sampler but i dont know how to create the URLs to transmit the data

I ended up using a mix of the above answer and what i saw in the documentation:

let fileDataA4 = fs.readFileSync('path/to/A4.mp3');

// create a Tone.js Player connected to the audio output
const player = new Tone.Player().toDestination();

let arrayBufferA4 = await new Blob([fileDataA4]).arrayBuffer();

// create a ToneAudioBuffer from the ArrayBuffer with loaded buffer
const bufferA4 = await player.context.decodeAudioData(arrayBufferA4);
                

let fileDataA5 = fs.readFileSync("path/to/A5.mp3");

let arrayBufferA5 = await new Blob([fileDataA5]).arrayBuffer();

const bufferA5 = await player.context.decodeAudioData(arrayBufferA5);
                
let sampler = new Tone.Sampler({
        urls: {
            "A4" : bufferA4,
            "A5" : bufferA5
        }
}).toDestination();
                
Tone.loaded().then(() => {
    sampler.triggerAttackRelease("C4", "1n")
})

This way, you only need to load 2 mp3 files, the sampler does the rest for you
