Strong increase in Sound Quality with PCM to DSD upsampling

Starting with Audirvana Plus release 2.5.1

This is the ultimate step in upsampling to send to the DAC the closest signal to the one used internally in its DAC chip immediately before the conversion to analog. This enables, with native DSD compatible DACs, to bypass all digital filters and processing done in the DAC chip by those done by Audirvana Plus.

The Mac computer CPU is much more powerful than the DAC chip and thus enables to use much more sophisticated upsampling algorithms to give strongly increased sound quality.

Please note that some very loud tracks have hard clipping. This can create trouble with the sigma-delta modulator that leads to one second of silence on one channel. If this happens, can you first try to set a lower value for the « Safe volume reduction before DSD upsampling » like -3dB? This should help as this rare issue is more likely to happen with very loud tracks.

Enjoy the new great improvement in sound quality!

 

With a DSD compatible DAC, there a new Forced upsampling option in the Audio Filters page of the preferences.

You can tune the output both the iZotope advanced filter settings, and the type of DSD filter.

On OS X 10.11.5 and iTunes 12.4 updates

Apple has just released two updates that break compatibility:

  • iTunes 12.4 breaks compatibility with some commands of the scripting interface used to control it, causing crash for applications that use them. Audirvana Plus has been updated in its version 2.5.1.1 to be compatible with both iTunes 12.4 and earlier versions, in its legacy iTunes integrated mode.
  • OS X El Capitan 10.11.5: May 21st update: Audirvana Plus has been updated in its version 2.5.1.4 to have Direct Mode compatible with 10.11.5. No more need to replace the kernel extension.
    Apple has unfortunately introduced a regression with 10.11.5 update that breaks Direct Mode.
    Until they fix it, you have to disable Direct Mode (option in Audio System page of preferences) to get playback to start.
    If you are Terminal-savvy, there is a way to get it back: you can replace the faulty kernel extension of 10.11.5, IOAudioFamily.kext, located in /System/Library/Extensions, by one from a former El Capitan version, if you have a backup. You may need to disable SIP to make this operation.

NEW: A+ Remote 1.5 and HIGHRESAUDIO VirtualVault

Newsweek (Europe edition 5/15/15): “(…)this one plays every available high- resolution format. The Audirvana Plus 2 is excellent quality and for €59 it’s pretty good value.”

Audirvana Plus 2.1: Enhancing the onboarding Experience

The modern library management features of Audirvana Plus bring strong convenience for sorting all your music tracks & albums. Helping to quickly find the piece you want to hear now, in this genre, from this artist. Or even easily perform A/B listening of the same classical piece by different performers.

The albums view to scan visually through the album cover images, or the tracks list view with its structured filter browser to quickly zero on The track in a hierarchical refining manner are very powerful tools.

But… all these need the audio files in the music library to have the proper metadata, and especially the album information ones. And this is not always the case, especially when coming from proprietary database librarian, or by just using the Finder hierarchy of file folders (and no library manager). Even more, some audio files formats like WAV, DSDIFF (.dff), are quite often missing any metadata.

The new Audirvana Plus 2.1 helps you in the on boarding to the full library management experience by:

  • Understanding file folders missing album metadata as albums in the album view, enabling to see them as if they were already actual albums. Option is then proposed to convert them to albums, storing in the files the album metadata
  • Retrieving all the iTunes album art information, even the one stored only in its database to have all albums with their cover image after just asking to synchronize the iTunes library. It is then proposed to save these hidden album images in the audio files metadata
  • And for those not yet ready to fully benefit from the library, it is possible to temporary add files directly in the Play Queue. This can be done by either drag files, folders, .m3u playlists from the Finder, or tracks from iTunes and drop them directly in the Play Queue, or use the “Open with…” command of the Finder on audio files.

And the good news is that this new major release is free as will be all the upcoming 2.x ones for all Audirvana Plus 2 users.
