/**
 * usePlayer is a custom React hook that provides functionalities to play, pause, stop, and manage audio playback using Tone.js.
 * It allows control over playback volume, looping, muting, and offers callbacks for various audio playback states.
 *
 * @param {UsePlayerProps} props - Configuration properties for the player.
 * @param {number} props.volume - Initial volume for the player (default: 5).
 * @param {boolean} props.loop - Whether the audio should loop (default: false).
 * @param {boolean} props.mute - Whether the audio should be muted (default: false).
 * @param {Function} props.onReady - Callback executed when the player is ready.
 * @param {Function} props.onPlay - Callback executed when the audio starts playing.
 * @param {Function} props.onPause - Callback executed when the audio is paused.
 * @param {Function} props.onStop - Callback executed when the audio is stopped.
 * @param {Function} props.onFinish - Callback executed when the audio finishes playing.
 * @param {Function} props.onError - Callback executed in case of an error.
 *
 * @returns {object} An object containing various properties and methods for audio playback control:
 * - player: The Tone.js Player instance.
 * - audioDuration: The duration of the loaded audio.
 * - isReady: Boolean indicating if the player is ready.
 * - isPlaying: Boolean indicating if the audio is currently playing.
 * - isFinish: Boolean indicating if the audio has finished playing.
 * - volume: Current volume of the player.
 * - loop: Boolean indicating if the audio is set to loop.
 * - mute: Boolean indicating if the audio is muted.
 * - time: Current playback time.
 * - percentage: Current playback progress as a percentage.
 * - pickTime: Method to set the playback start time.
 * - init: Method to initialize the player with an AudioBuffer.
 * - play: Method to start playback.
 * - pause: Method to pause playback.
 * - stop: Method to stop playback.
 * - getTime: Method to get the current playback time.
 * - setPickTime: Method to set a specific playback time.
 * - setVolume: Method to set the volume.
 * - setLoop: Method to toggle looping.
 * - setMute: Method to toggle mute.
