Note that decoding the signal beyond twice the sampling rate of the encoded file (for the few rare recordings actually made above 96kHz) can only be done in a DAC MQA. In this case, Audirvana brings, in addition to the general Sound Quality improvement, the decoding of the MQA file that would be played only at little above CD quality otherwise, losing all its high resolution benefits. Non MQA capable audio devices can benefit from the high resolution (doubled sample rate compared to the encoded file one) thanks to the MQA decoder integrated in Audirvana. By MQA decision, the second unfolding (to 176.4 or 192kHz) can be performed only in a MQA renderer/decoder DAC. Is the MQA light appearing only when the DAC is decoding and not when it’s rendering only?Īudirvana integrates the MQA Core Decoder that performs the first unfolding (up to 88.2 or 96kHz) to benefit from the high resolution of the MQA audio files even without an MQA audio device.
