How to turn off noise reduction, echo cancellation, and automatic gain control?

If your classroom integrates or uses audio mixing or other tools, and you want to turn off noise reduction, echo cancellation, and gain control functions, add the following code to packages/agora-classroom-sdk/src/infra/api/index.tsx:

 if (AgoraRteRuntimePlatform.Electron === AgoraRteEngineConfig.platform) {
      rtcSDKParameters = [
        { 'rtc.audio.aec.enable': false },
        { 'rtc.audio.agc.enable': false },
        { 'rtc.audio.ans.enable': false },
      ];
    } else {
      rtcSDKParameters = [
        {
          MEDIA_DEVICE_CONSTRAINTS: {
            audio: {
              autoGainControl: false,
              echoCancellation: false,
              noiseSuppression: false,
            },
          },
        },
      ];
    }
