PlanetKit 6.2.2

Release date: 2026-01-29

Add auto gain control mode for translators

• In translation rooms, translators typically speak while simultaneously listening to another participant.
  • In this scenario, auto gain control does not increase the microphone volume even when it is low, because the situation is detected as an echo environment due to double talk (overlapping speech).
  • This behavior causes an issue where the translator's microphone volume cannot be increased when it is below a certain level.
  • To address this, we provide a separate mode that allows the microphone volume to be increased even in such echo environments for translators.
• This enhancement adds a new mode to resolve issues encountered with the default PLNK_AUTO_GAIN_CONTROL_TYPE_HARDWARE, ensuring the translator's voice can be delivered clearly even during overlapping speech.

Example code

Set the PLNK_AUTO_GAIN_CONTROL_TYPE_HARDWARE_ECHO_TOLERANCE mode if the user's role is translator.

class YourConference {
public:
    void SetAutoGainControlModeForTranslator() {
        PlanetKit::SendVoiceProcessorPtr voiceProcessor = m_pConference->GetSendVoiceProcessor();

        voiceProcessor->SetAutoGainControl(
            PLNK_AUTO_GAIN_CONTROL_TYPE_HARDWARE_ECHO_TOLERANCE,
            nullptr,
            [](void* pUserData, bool bSuccess) {
                std::wcout << L"AGC configured with result: " << bSuccess << std::endl;
            }
        );
    }

private:
    PlanetKit::PlanetKitConferencePtr m_pConference;
};
