The Sound Quality redefined: Direct Mode BETA available

Direct Mode shortens further the audio signal by bypassing all CoreAudio, even its lowest level HAL layer.

In addition, the Integer Mode that was no more available in Lion is back for all the devices that offered it in Snow Leopard!

As it is now at a good level of maturity, I’ve decided to release Direct Mode as a public beta for you to enjoy it now. I will continue to improve it, taking you feedback into account, and pursuing the optimization ideas I’ve identified.

The beta is no longer available for download. Directly download the official version that now includes Direct Mode.

Be sure to enable Direct Mode in the Audio System panel of Audirvana Plus user preferences.

And enjoy!

Note that as this is a BETA, the automated updates are disabled. You’ll get notification of updates in this post, in #audirvana tweets, or on Facebook (Audirvana Plus). And use the link above to download the latest version. update (June 3rd, 2012)
