MQA file is verified and authenticated by the MQA decoder. When the MQA file is played for the first time, BluOS initially indicates it as a (24-bit HD file). After authentication, the indicator is replaced with the (MQA logo). This process happens seamlessly within the first few seconds of playback and the audio is uninterrupted or unaltered.
