/**
 * useFetchAudio is a custom React hook for fetching and decoding audio data from a specified URL.
 * It handles the entire process from making an HTTP request to processing the audio data.
 *
 * @param {UseFetchAudioProps} props - The configuration properties for fetching the audio.
 * @param {string} props.url - The URL of the audio file to be fetched.
 * @param {RequestInit} [props.requestOptions] - Optional configuration for the fetch request.
 * @param {Function} [props.onSuccess] - Optional callback to be executed when the audio is successfully fetched and decoded.
 * @param {Function} [props.onError] - Optional callback to be executed in case of an error during fetching or decoding.
 *
 * @returns {object} An object containing several states and a function to initiate the audio fetching:
 * - pending: A boolean indicating whether the request is in progress.
 * - fetched: A boolean indicating whether the audio has been successfully fetched and decoded.
 * - error: A boolean indicating if an error has occurred.
 * - errorMessage: A string containing the error message if an error has occurred.
 * - response: The response object from the fetch request.
 * - audioBuffer: The decoded audio data as an AudioBuffer.
 * - fetchAudio: A function that initiates the fetching and decoding process.
 *
 * This hook is useful in scenarios where you need to retrieve audio files from a server and process them for web audio applications.
