The settings associated with each algorithm are slightly different, but both will allow you to define the multiple of the sampling rate to be applied (x2, x4 etc.) as well as to fine-tune various filters, essentially to neutralize the artifacts that result from these operations. This will facilitate the DAC’s work by giving it a stream that contains more precise points at the base. You can use Audirvāna to carry out this operation upstream: it will benefit from the computer’s much greater computing power, and with a high-performance algorithm. They therefore systematically oversample the signal just before the actual conversion, but work with limited computing power and more or less powerful algorithms, particularly for chip-cost and latency reasons. Indeed, almost all DACs today on the market operate on a very-high-frequency switching-principle with a resolution of only a few bits. This can improve sound quality, sometimes quite noticeably, depending on your system’s converter and the settings you choose. 'You can oversample your audio files directly in Audirvāna before playback on your system, using one of the two built-in high-performance algorithms: SOX (SoundExchange) and R8 Brain. Benefiting from the processing power of your computer, much higher than the internal capacity of the DAC, Audirvāna can run more sophisticated and demanding oversampling algorithms, and feed your DAC with a signal containing more accurate data that facilitates the interpolation work.'Ĭlick to expand.What definitely could affect the sound is the filtering done with oversampling Today, most DACs operate at very high internal frequencies and low resolution. With quality as sole priority, Audirvāna does not have to seek a compromise between processing speed and accuracy and can thus mobilize the computer’s computing power using the best algorithms. 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. I have used Roon a lot and I think the interface. If bits are ‘just bits’ then Audirvana will sound identical to iTunes (or any other Windows/MacOS music player). In addition, Audirvāna delivers a ‘ready-to-play’ digital audio stream that allows your converter to operate under optimal conditions, i.e. I use it exclusively on a mac mini server and run it from the very good iPad app. The thing I like most about Audirvana is that its 30-day trial is one of the easiest ways for anyone to hear (or not) digital audio’s differences for themselves and for free. This limits processor activity during playback and protects the music from playback jitter and possible signal interference by stabilizing the computer power supply and limiting processor activity to the bare minimum: minus 0.5% CPU load less than 0:5% of CPU load. 'Audirvāna loads, decodes and processes the entire audio data of a track prior to playback in a buffer memory.
