Audirvāna loads, decodes and processes the entire audio data of a track prior to playback in a buffer memory. During playback, the computer power supply is stabilized and processor activity limited to the bare minimum: less than 0.5% of CPU load.
Audirvāna also delivers a ‘ready-to-play’ digital audio stream that allows your converter to operate under optimal conditions, i.e. a PCM (or DSD) stream already decoded, which takes into account the characteristics of your DAC – for the order of reception of data beyond 16bits for example – and reduces the tasks to be performed at its level.
Upsampling using Audirvāna’s integrated algorithms can also help. Most DACs operate at very high internal frequencies and low resolution. Therefore the audio data is converted and oversampled. This is done by the DAC using basic algorithms since those chipsets have limited computing power. Audirvāna can run more sophisticated and demanding oversampling algorithms using the much higher processing power of the computer. This can help the DAC be more quiet and accurate, but the benefit depends on each models characteristics.
