#AUDIRVANA PLUS 3.2 USER MANUAL SOFTWARE#

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: I set this to Automatic.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… With BitPerfect I found turning on dithering to yield a better sound over no dithering.

Dithering gives you a choice whether or not to have dithering on the resampling process.

Most of the time I use 88.2kHz, and sometimes 96kHz.

Upsampling gives you a set sample rate to upsample on the fly all your files to.

The recommended setting here is SoX 14.3.2 VHQ Intermediate

SRC gives you a choice between running on Apple’s Core Audio resampler to the SoX resampler.

Here are some of the options you may want to look into: If you’d like to, you can play around with the upsampling settings on the “Sound” tab of the Preferences window (Preferences > Sound). In fact, the only thing that indicates BitPerfect’s presence on your playback system is the tiny icon on the upper right corner of your desktop, next to the Wifi, Speaker Volume, and Battery indicator icons.Įven though the updated BitPerfect offers more customization options than the previous one, the default settings are good and you don’t really need to change anything except for setting your output device. It is designed to run together with Itunes, and so you never see a BitPerfect player window.

The minimalistic interface of BitPerfect makes it unique in comparison to the other players. It has retained all the simplicity and user-friendly interface that I love about BitPerfect, but with some powerful new addition including a 64-bit playback engine, a high quality sample rate conversion powered by SoX, especially with user configurable file upsampling features (using the SoX upsampling engine). On February 1th, 2012, Tim posted an updated version of BitPerfect, and the 1.0 version is a big step up from the last one I use for the BitPerfect review.
