Again, there’s no timing information as such (other than embedded information about the sample rate): the data is just in order. In this buffer, you will find, in some form or another, the audio samples. When the data comes to the point where it has to leave the computer, whether it’s the audio interface or the USB interface, you’ll never guess what you’ll find it in…yup, a buffer.
Now, we could trace the passage of this data all over the computer, round the Northbridge and Southbridge, but luckily it isn’t important. I’ve oversimplified the data composition: it’s put into frames with control information, which have data removed from them, encoded and combined with control characters for transmission over the SATA interface, but the bottom line is that it’s ultimately just sequential data, one sample following another. There isn’t any timing information as such: it’s just sequential data. My previous statement was perhaps overly simplified, so here’s a longer example.Ĭonsider some uncompressed audio data, which your hard drive has just read into its internal buffer (assuming it’s uncompressed simply for the simplicity of the example rather than because it’s meaningful in terms of SQ).

Suggested mechanism of audibility: Direct effect of software on jitter (ie, not the power supply). Here is the slightly more technical searching question-y bit: This is good to boost apparent detail level, but I tend to find that the even order upsampling produces a more natural sound.įrom my perspective, we really *should* be asking “How?” and other sorts of questions: when everything is accepted at face value you end up like The Absolute Sound, which recently insisted that two completely identical files, played under identical conditions, sound different… A standard CD file (44.1 kHz) would be resampled to either 96kHz, 192kHz, or 384kHz depending on the maximum limit of your DAC. “Maximum sample rate upsampling” upsamples the files to the maximum limit your DAC will accept. I tend to agree, based on my listening impressions. Some argue that this yields the most natural sound. A standard CD file (44.1kHz) would be resampled to either 88.2kHz or 176.4kHz. “4x or 2x” means upsampling to the even order. This will force all files to be upsampled to a specific sample rate. “Forced upsampling” (Preferences > Audio Filters).“Maximum memory allocated for tracks pre-load” (Preferences > Audio System).Some additional settings that you might want to play around with in the preferences panel are:

(or SRC libSampleRate on Free Audirvana). Audio Filters > Make sure it’s on iZotope 64-bit SRC Converter, quality slider at Best.Audio System > Yes on both Exclusive Access Mode and Integer Mode.Audio System > Preffered Audio Device > Choose your DAC here.You start up the player, add files to the playlist, open the preferences panel and set up the following: Both versions give you the ability to create playlists, complete with the playlist window and FLAC support. Especially in comparison to the Sonic Studio players, the two Audirvanas look like a big bargain in terms of the features you get for the price. Both versions come loaded with functions such as FLAC support, unlimited maximum sample rate, automatic sample rate conversion, exclusive access mode, playback from memory and integer mode. The Audirvana players are very easy and straightforward to use. Audirvana+ comes with a superior Benchmark iZotope 64bit-SRC sample rate converter, while the free version comes with an open source SRC libSampleRate 32bit sample rate converter.The sonic engine on Audirvana+ comes with even more optimizations, making the sound quality a step up from the free version (what I observed is a more spacious soundstage and a far better layering on the Plus version).Itunes Integration is only available with Audirvana+.
