* AudioBox - 音声再生・合成Box
|
||||
*
|
||||
* ## 📝 概要
|
||||
* Web Audio APIを使用してブラウザでの音声再生、
|
||||
* 合成、エフェクト処理を統一的に管理するBox。
|
||||
* ゲーム、音楽アプリ、オーディオビジュアライザー開発に最適。
|
||||
*
|
||||
* ## 🛠️ 利用可能メソッド
|
||||
*
|
||||
* ### 🔊 基本再生
|
||||
* - `loadAudio(url)` - 音声ファイル読み込み
|
||||
* - `play()` - 再生開始
|
||||
* - `pause()` - 一時停止
|
||||
* - `stop()` - 停止
|
||||
* - `setVolume(volume)` - 音量設定 (0.0-1.0)
|
||||
*
|
||||
* ### 🎵 音声合成
|
||||
* - `createTone(frequency, duration)` - 純音生成
|
||||
* - `createNoise(type, duration)` - ノイズ生成
|
||||
* - `createBeep()` - システム音
|
||||
*
|
||||
* ### 📊 解析・ビジュアライザー
|
||||
* - `getFrequencyData()` - 周波数解析データ取得
|
||||
* - `getWaveformData()` - 波形データ取得
|
||||
* - `getVolume()` - 現在の音量レベル
|
||||
*
|
||||
* ### 🎛️ エフェクト
|
||||
* - `addReverb(room)` - リバーブエフェクト
|
||||
* - `addFilter(type, frequency)` - フィルター適用
|
||||
* - `addDistortion(amount)` - ディストーション
|
||||
*
|
||||
* ## 💡 使用例
|
||||
* ```nyash
|
||||
* local audio, visualizer
|
||||
* audio = new AudioBox()
|
||||
*
|
||||
* // 効果音再生
|
||||
* audio.loadAudio("sounds/explosion.wav")
|
||||
* audio.setVolume(0.7)
|
||||
* audio.play()
|
||||
*
|
||||
* // 音声合成
|
||||
* audio.createTone(440, 1000) // A4音を1秒
|
||||
* audio.createBeep() // システム音
|
||||
*
|
||||
* // オーディオビジュアライザー
|
||||
* local freqData = audio.getFrequencyData()
|
||||
* // freqDataを使用してcanvasに描画
|
||||
* ```
