### Checking Opus Library Loading Status in JavaScript

Source: https://github.com/xinnan-tech/xiaozhi-esp32-server/blob/main/main/xiaozhi-server/test/abbreviated_version/test.html

This function attempts to verify if the Opus decoding library (expected as a global `Module` object from Emscripten) has loaded successfully. It checks for the presence of the `Module` object, specific decoder functions (`_opus_decoder_get_size`), and handles cases where the module might still be initializing by registering an `onRuntimeInitialized` callback. It updates UI status and enables/disables the start button based on success or failure.

```JavaScript
function checkOpusLoaded() {
  try {
    // 检查Module是否存在（本地库导出的全局变量）
    if (typeof Module === 'undefined') {
      log("Module对象不存在", "error");
      throw new Error('Opus库未加载，Module对象不存在');
    }
    // 记录Module对象结构以便调试
    log("Module对象结构: " + Object.keys(Module).join(", "));
    // 尝试使用全局Module函数
    if (typeof Module._opus_decoder_get_size === 'function') {
      window.ModuleInstance = Module;
      log('Opus库加载成功（使用全局Module）', "success");
      updateScriptStatus('Opus库加载成功', 'success');
      // 启用开始录音按钮
      startButton.disabled = false;
      statusLabel.textContent = "待机";
      // 3秒后隐藏状态
      setTimeout(() => {
        const statusElement = document.getElementById('scriptStatus');
        if (statusElement) statusElement.style.display = 'none';
      }, 3000);
      window.opusLoaded = true;
      return true;
    }
    // 尝试使用Module.instance
    if (typeof Module.instance !== 'undefined' && typeof Module.instance._opus_decoder_get_size === 'function') {
      window.ModuleInstance = Module.instance;
      log('Opus库加载成功（使用Module.instance）', "success");
      updateScriptStatus('Opus库加载成功', 'success');
      // 启用开始录音按钮
      startButton.disabled = false;
      statusLabel.textContent = "待机";
      // 3秒后隐藏状态
      setTimeout(() => {
        const statusElement = document.getElementById('scriptStatus');
        if (statusElement) statusElement.style.display = 'none';
      }, 3000);
      window.opusLoaded = true;
      return true;
    }
    // 检查是否有其他导出方式
    log("Module上可用方法: " + Object.getOwnPropertyNames(Module).filter(prop => typeof Module[prop] === 'function').join(", "));
    if (typeof Module.onRuntimeInitialized === 'function' || typeof Module.onRuntimeInitialized === 'undefined') {
      log("Module.onRuntimeInitialized 尚未执行，等待模块初始化完成...");
      // Module可能未完成初始化，注册回调
      Module.onRuntimeInitialized = function() {
        log("Opus库运行时初始化完成，重新检查");
        checkOpusLoaded();
      };
      return false;
    }
    throw new Error('Opus解码函数未找到，可能Module结构不正确');
  } catch (err) {
    log(`Opus库加载失败: ${err.message}`, "error");
    updateScriptStatus(`Opus库加载失败: ${err.message}`, 'error');
    statusLabel.textContent = "错误：Opus库加载失败";
    return false;
  }
}

### Stopping Microphone Test in JavaScript

Source: https://github.com/xinnan-tech/xiaozhi-esp32-server/blob/main/main/xiaozhi-server/test/opus_test/test.html

This function stops an active microphone test. It resets UI elements, cancels any ongoing animation frames, stops the audio stream from the microphone, closes the Web Audio API context, and hides the audio meter.

```JavaScript
function stopMicTest() {
  const audioMeter = document.getElementById("audioMeter");
  const testMicBtn = document.getElementById("testMic");
  log("停止麦克风测试");
  window.testMicActive = false;
  testMicBtn.textContent = "测试麦克风";
  testMicBtn.style.backgroundColor = "#fbbc05";
  if (window.testMicAnimationFrame) {
    cancelAnimationFrame(window.testMicAnimationFrame);
  }
  if (window.testStream) {
    window.testStream.getTracks().forEach(track => track.stop());
  }
  if (window.testContext) {
    window.testContext.close();
  }
  audioMeter.style.display = "none";
}
```
