Saving an opus stream from a voice channel to .mp3/.wav/.webm

So with the help of another thread here, I managed to save an opus stream to .ogg. Now, I need to save that same opus stream to an .mp3 file instead, and i’m even more stuck than last time. Can I somehow save the audio to a .mp3 or .wav file instead? Help would be much mich appreciated…

const { opus } = require("prism-media");

//other stuff

let opusStream = voiceReceiver.subscribe(userId, {
        end: {
            behavior: EndBehaviorType.AfterSilence,
            duration: allowedPauseDurationForInputVoice
        }
    });
    const oggStream = new opus.OggLogicalBitstream({
        opusHead: new opus.OpusHead({
            channelCount: 2,
            sampleRate: 48000
        }),
        pageSizeControl: {
            maxPackets: 10
        }
    });

    let buffer = [];
    oggStream.on("data", (chunk) => {
        buffer.push(chunk);
    });

    opusStream.on("end", async () => {
        logReliably(user.globalName + " stopped speaking. " + getTimeElapsedSinceLastCall());
        oggStream.destroy()
        fs.createWriteStream('output.ogg').write(Buffer.concat(buffer))
        buffer = []
    });

    opusStream.pipe(oggStream)

const { opus } = require("prism-media");

//other stuff

let opusStream = voiceReceiver.subscribe(userId, {
        end: {
            behavior: EndBehaviorType.AfterSilence,
            duration: allowedPauseDurationForInputVoice
        }
    });
    const oggStream = new opus.OggLogicalBitstream({
        opusHead: new opus.OpusHead({
            channelCount: 2,
            sampleRate: 48000
        }),
        pageSizeControl: {
            maxPackets: 10
        }
    });

    let buffer = [];
    oggStream.on("data", (chunk) => {
        buffer.push(chunk);
    });

    opusStream.on("end", async () => {
        logReliably(user.globalName + " stopped speaking. " + getTimeElapsedSinceLastCall());
        oggStream.destroy()
        fs.createWriteStream('output.ogg').write(Buffer.concat(buffer))
        buffer = []
    });

    opusStream.pipe(oggStream)

How to save a user's voice to a local file? (.mp3 or .ogg)

let listener = voiceReceiver.subscribe(userId, {
        end: {
            behavior: EndBehaviorType.AfterSilence,
            duration: allowedPauseDurationForInputVoice
        }
    });

    const listenBuffer = [];

    listener.on("data", (chunk) => {
        listenBuffer.push(chunk);
    });

    listener.once("end", async () => {
        logReliably(user.globalName + " stopped speaking. " + getTimeElapsedSinceLastCall());
        const completeBuffer = Buffer.concat(listenBuffer);
        
        const audioEncoder = new OpusEncoder(48000, 2);
                //Save to ./test.ogg ?
    });

let listener = voiceReceiver.subscribe(userId, {
        end: {
            behavior: EndBehaviorType.AfterSilence,
            duration: allowedPauseDurationForInputVoice
        }
    });

    const listenBuffer = [];

    listener.on("data", (chunk) => {
        listenBuffer.push(chunk);
    });

    listener.once("end", async () => {
        logReliably(user.globalName + " stopped speaking. " + getTimeElapsedSinceLastCall());
        const completeBuffer = Buffer.concat(listenBuffer);
        
        const audioEncoder = new OpusEncoder(48000, 2);
                //Save to ./test.ogg ?
    });

completeBuffer definitely holds data, but I tried everything I could find in documentation/forums and still failed to save that buffer's contents as a file. I also tried saving the voiceReceiver stream, and that failed to output a playable audio file as well. Help would be much appreciated!
