To fetch audio data using the Axios library in Node.js and play it using the Web Audio API, you can follow these steps:

1. Fetch the Audio Data

Use Axios to make a POST request to the ElevenLabs API and retrieve the audio data as a binary stream. Ensure you include the necessary headers and parameters.

import axios from "axios";

const fetchAudioData = async () => {
  try {
    const response = await axios({
      method: "post",
      url: "https://api.elevenlabs.io/v1/text-to-speech/<your_voice_id>/stream",
      params: {
        model_id: "eleven_multilingual_v2",
        output_format: "mp3_44100_128", // Specify the desired format
      },
      data: {
        text: "Hello, this is a test message.",
        voice_settings: {
          stability: 0.5,
          similarity_boost: 0.8,
        },
      },
      headers: {
        "xi-api-key": "<your_api_key>",
        "Content-Type": "application/json",
      },
      responseType: "arraybuffer", // Expect binary data
    });

    return response.data; // Return the audio data
  } catch (error) {
    console.error("Error fetching audio data:", error.message || error);
    if (error.response) {
      console.error("Response status:", error.response.status);
      console.error("Response headers:", error.response.headers);
    }
  }
};

2. Play the Audio Using Web Audio API

Once you have the audio data, you can decode it and play it using the Web Audio API.

const playAudio = async (audioData) => {
  try {
    const audioContext = new (window.AudioContext || window.webkitAudioContext)();
    const audioBuffer = await audioContext.decodeAudioData(audioData);

    const source = audioContext.createBufferSource();
    source.buffer = audioBuffer;
    source.connect(audioContext.destination);
    source.start(0); // Play the audio immediately

    console.log("Audio is playing...");
  } catch (error) {
    console.error("Error playing audio:", error);
  }
};

// Fetch and play the audio
const main = async () => {
  const audioData = await fetchAudioData();
  if (audioData) {
    playAudio(audioData);
  }
};

main();

Key Points

1. Replace <your_voice_id> and <your_api_key> with your actual ElevenLabs voice ID and API key.
2. Ensure the output_format matches your requirements (e.g., MP3 format).
3. The responseType: "arraybuffer" in Axios ensures the audio data is fetched as binary data, which is required for decoding with the Web Audio API.

This code will fetch the audio data from the ElevenLabs API and play it using the Web Audio API in the browser.
