Select the location of the proxy files This allows to select the location of the root folder where all the generated proxy files will be placed. To avoid having iTunes duplicate these proxy files and eat too much disk space, it is recommended to unselect in iTunes preferences, Advanced tab, the options Keep iTunes Media Folder Organized and Copy files to iTunes Media Folder when adding to library. After creation, neither the proxy files, nor the original files should be moved or deleted.
This would break the link and prevent correct playback when using iTunes for controlling Audirvana Plus. Note this is the way iTunes handles these M3U files - Automatically start playback when Audirvana is opened with a track or playlist usually when double-clicking on such a file in the Finder - Save the current playlist when exiting, and automatically reload it the next time Audirvana is opened Volume Control The volume control knob can be rotated by using a vertical, horizontal, or a rotation motion with the mouse.
It is used if available connected when starting playback, otherwise the system default device is used. The preferred or default if not connected audio device name is displayed in the Active Audio Device paragraph, as well as its handled sample rates.
Simple Decimation the algorithm used before version 1. This enables a further shorter audio signal path for better sound quality, and gives possibility to enable Integer Mode in Lion and later. Integer mode: In this mode Audirvana Plus directly sends the audio data to the lowest level in CoreAudio, bypassing the driver audio mixer and the format converter.
This enables to achieve very high sound quality. There are two different streaming modes in Integer Mode: Mode 1 that brings the highest transparency, and soundstage depth Mode 2 that is more on the warm side Choose the one that fits the best your system and listening tastes.
Increasing this value will reduce further the disk accesses and the associated interferences. As a rule of thumb it is best to leave at least 2. To give enough time to the DAC to synchronize its clocks upon a sample rate change and avoid missing the first notes of a track , set the right Spl rate switching latency depending on you DAC e. In addition if the bridge is offering both 24bit and 32bit bitdepth, you can limit the bitdepth to 24bit by selecting Limit max bitdepth to 24bit instead of 32bit.
Multichannel capability The total number of channels of the audio device is shown, as well as the channels configuration in use. In the case the audio device is used only in two channels stereo output, the option Use as stereo only can be used to optimize the audio path. After having selected the audio device in the list left of the main window , click on Configure Speakers… to raise the speakers selection popup.
There you can set the channel mapping for the multichannel configuration or Stereo if you have selected the Use as stereo only setting. Note that restarting Audirvana Plus is needed after any change made in the channels configuration in AudioMidi Setup.
Sample Rate Conversion Sample Rate Conversion happens when - The audio device does not handle the audio track sample rate - Upsampling is forced.
Sample Rate Converter Settings Use the quality slider to set the desired quality level. Note that with high initial sample rates, the best quality setting especially for Apple CoreAudio may be demanding too much computing power for some Macs thus giving in playback pauses.
For iZotope bit SRC, you have access to advanced detailed parameters to tune the sample rate converter filters:. Higher steepness will reject unwanted frequencies but cause more ringing in the time- domain and a higher CPU load - Max filter length: controls the memory and CPU usage used by the resampling filter.
Default value k should be sufficient for most applications. Can be increased for getting vey high quality output for very high sample rates e. DSD downsampling - Cutoff: cutoff frequency is computed by multiplying the Nyquist frequency by the value of the cutoff scaling parameter.
Any frequencies in the stop-band, which are not fully attenuated, will result in aliasing, which is when these unwanted frequencies are mapped to different frequencies and mixed into the output.
Use higher values for better quality and use lower values to minimize CPU load. The steeper the filter, the greater the amount of ringing. There are two general types of ringing: pre-ringing and post-ringing. Pre- ringing will smear transients earlier in time, while post-ringing will smear transients later in time.
This control allows users to select pre-ringing, post- ringing, or anywhere in between. A value of 1. A value of 0. Setting intermediate values allows a continuous tradeoff between pre-ringing and post-ringing and allows users to linearize phase in the pass-band as much as possible.
Volume control type Your DAC may or may not offer remote volume control master or digital. Thus a dithering algorithm is used to lessen the audible impact of this digital volume control. Dithering engine tweaking When using dithering volume control, you have access to advanced parameters for the dithering engine: - Dithering Type: Controls the type of dithering. Type 1 dither is a traditional dither based on a rectangular probability distribution function PDF , and Type 2 dithering is a traditional dither based on a triangular PDF.
Dithering noise can be shaped in order to make it less audible. Simple noise shaping performs simple high-pass filtering on the noise. Clear noise shaping aggressively moves the noise toward the Nyquist frequency. Psych 5 is a 5th- order filter designed to move noise away from audible bands, and Psych 9 is a 9th-order filter with similar characteristics.
The choices range from no noise shaping to very aggressive noise shaping, providing. The None and Low settings can leave some non-linear quantization distortion or dither noise modulation, while higher settings completely eliminate the non-linear distortion at the expense of a slightly increased noise floor. The Normal setting should suffice for most cases. However, after noise shaping, especially in aggressive dithering modes, the high- frequency dither noise is significantly amplified, and the overall dither signal can show spurious peaks up to - 60 dB FS.
If such high peaks are undesirable, you can enable the Limit Peaks option to effectively suppress the spurious peaks in the noise-shaped dither. Truncation results in harmonic quantization distortion that adds overtones to the signal and distorts the timbre. In this case you can enable the Suppress Harmonics option to slightly alter the truncation rules, moving the harmonic quantization distortion away from overtones of audible frequencies. This option doesn't create any random dithering noise floor.
Instead it works more like truncation, but with better tonal quality in the resulting signal. This option is applicable only in the modes without dithering noise and without aggressive noise shaping.
Use this setting for this purpose. Then select in the drop down lists the Audio Units you want to use. Configuration of each Audio Unit plugin can be done either offline by clicking on Configure Click on Apply when done with the settings to save them.
Presets for each Audio Unit type can be saved or recalled. Note that the presets can be saved on the user domain, or local to the system possible only if the user has the authorization to modify system settings. Or configuration can be made in realtime during playback by using the option Realtime AudioUnits control and setup popup windows will open upon playback start for each Audio Unit. Note that with the realtime setup the AudioUnits rendering is done during playback, and thus, for maintaining the optimal sound quality, this option should be set to off after the AudioUnits configuration is completed.
This will ensure the rendering is done during track loading process, before playback. The audio signal processing is done in the following order: 1 File loading and decoding 2 Sample rate conversion if needed 3 Audio Units in the top to down order. Spotlight, Time Machine are resource hungry background processes that create important activity of the disk drives, and thus interferences detrimental to the sound quality. The automated detection of iDevices on USB can even cause audible clicks. It is therefore strongly advised to enable SysOptimizer.
It will deactivate these interfering background services at playback start, and reactivate them upon stop. For best sound quality, Audirvana Plus can completely deactivate sound playback by iTunes. Note that this also prevents any other application to output sound during playback. In addition, to increase further the Sound Quality, you can deactivate convenience functions: - Volume Control: Audirvana Plus interacts with iTunes on a regular basis to exchange the volume control values.
Furthermore, the time indication remains to during playback. Select the DAC in the drop down list of the popup window. Click on Select to close the popup. Note for Macs before end If you encounter some short and frequent audio dropouts and you have a Mac from before end, this may be due to insufficient USB bus power.
Of course no other device shall be connected on the same hub. One may be already shared with an internal peripheral like the built-in iSight webcam. To check your DAC is connected to the right plug: 1. Scroll the left column down to the Hardware section 3. Select USB 4. Connect any other peripherals, such as external hard drives, to another bus, or even to a Firewire or Thunderbolt one.

Main window operations Transport Buttons Play: Starts the audio playback, and the following initialization steps if enabled in the user preferences : - Take exclusive access of the audio device - Select native device format audio stream for playback integer mode - Deactivate the background process that might have been interfering e.
Keyboard shortcut: Space Pause: Pause the playback. Keyboard shortcut: Space Stop: Fully stop audio playback, release the audio device, and restore the deactivated OSX services.
Other buttons Disp. Warning: For local volumes this will mean the audio files are moved to the trash, but for network shares, the audio files will be deleted permanently. An additional warning message will ask to confirm this permanent, not undoable operation. Please note that some audio files may contain several tracks e.
In this case, deleting permanently the audio file will remove all of its tracks from the database. This is stated in a special warning message as shown in the example below:. Metadata ediEng The metadata for a track, multiple tracks at a time, and an album can be edited by using the "Show Metadata" command of the View menu or Cmd I shortcut.
This opens the metadata editor panel on the right of Audirvana Plus window, displaying the metadata of the selected items. Its contents are updated when the selection e. So the metadata panel can be used to show the detailed metadata of a track or album , even when not willing to edit it. When any metadata value is modified, two buttons appear at the bottom of the metadata editor panel as shown above:. The corresponding audio file needs to be accessible for the save operation to work - Revert: shortcut Cmd.
Discard any changes, and revert to the tracks previous values. It presents four blocks of metadata that can be collapsed or expanded by clicking on the Hide or Show button on the right of their header bar. Corresponding audio file name, and full path the full path can be hidden by clicking on the small triangle left of the file name. Clicking on the arrow on the right of the path reveals the audio file in a Finder window.
The button Recompute ReplayGain triggers re analysis of the audio file dynamics. Track title, Grouping title. Example of usual use of the Grouping metadata is to group movement tracks of the same piece e. The track title can be complemented with a name used for sorting.
Artists list, Composer name. Genre name. When typing the first letters of the name, a list of genres already in the database is presented in a popup menu for faster typing. Disc Number, total discs count in the set 8.
Track individual rating from 0 to 5 stars. Note that to set the value of 0, the easiest way is usually to drag the rating to the left as if it was a cursor. The name of the conductor usually in classical music 2. The orchestra or band name 3. The name of the soloist 4. The main instrument e. Piano, Violin, Guitar 5. The piece format e. Sonata, Concerto, Symphony, Opera or a style detailing the genre for non classical music 6.
The period of the music e. Baroque, Romantic The Conductor, Ensemble, and Soloist are automatically added to the artists list of the track they are all artists. Album title. Changing the title enables to attach the track to already existing album when selecting one from the list in the popup menu that appears when typing the first letters of the album title , or create a new one. Album artist name 3.
Album image. The album information cannot be changed in the track metadata editor. Album title, artists, image, rating can be modified in the Album metadata editor. The Album metadata editor is displayed when an album is selected and no track is selected. Free text comments. MulEple tracks When multiple tracks are selected, the metadata panel displays the metadata fields whose values are common among the selected tracks. The other fields are left empty. Enables to change the album title 2. Album artist.
The main artist of the album 3. Album front cover image. This can be changed either by dropping a new image on it, or by pressing the change button and then selecting an image file in the file selection popup window. Album rating. The whole album rating from 0 to 5 stars. Such a situation will make more difficult finding a track or an album e. Select them all using Cmd A shortcut. It makes possible to rename the name of the artist displayed and the one used for the sorting.
Please note saving those changes can take some time, especially if the renamed artists are in numerous tracks. All audio files referencing the renamed artists are updated in this save process. This also gives you the opportunity to use the Remote application running on iPhone or iPad for remote control. But note that the sound quality will be affected by having iTunes running along with Audirvana Plus.
In this mode, the Audirvana Plus main window is still active and can be raised if desired by clicking on the Audirvana Plus dock icon. Note that Audirvana Plus will play all iTunes music files except DRM protected, tracks on the Cloud or on Home Sharing libraries , and automatically deactivate itself for the Internet radios that will still be played directly by iTunes.
You can switch between the classic playlist mode and the complete iTunes integration by using the iTunes Integrated Mode command in the Audirvana Plus menu.
Volume Control Volume Knob: There are three types of volume control, depending on the device capabilities, and the user preferences: - Master red cursor : the device provides a remote volume control feature that is inside the DAC and normally of optimal quality. See your DAC user manual for this. Should typically be set at 0dB to ensure bit perfect output.
If the device provides no volume remote control and dithered volume control is not enabled in user preferences, the volume control knob is inactive. Depending on the user preferences, the knob is rotated using a vertical default , horizontal or rotational motion of the mouse. The album image is gathered from, in order of priority: - The image embedded in the audio file - A folder.
Technical information is given at the bottom of the LCD screen: - On the left: Playing track file type, and native bit depth and sample rate - On the right: The DAC current bit depth and sample rate.
On the right column are some playback status indicators: - CPU: the red CPU sign indicates an unexpected pause in audio playback. The most frequent source of such issues is a lack of available memory. Try to exit other memory hungry applications e. Track playing posiEon The current playing position in minutes:seconds is displayed on the left, and the track total duration is on the right of the playing position cursor.
Dragging the playing position cursor or clicking directly on a different position makes the playback seek to this position. Inside this playing position track is given information about the loading progress, in form of a grey progress bar. Note this is the way iTunes handles these M3U files - Automatically start playback when Audirvana is opened with a track or playlist usually when double-clicking on such a file in the Finder - Save the current playlist when exiting, and automatically reload it the next time Audirvana is opened - Display playlist, library tracks using a larger font.
ApplicaEon Updates Audirvana Plus can automatically connect to audirvana. Miscellaneous opEons - During playback, Audirvana Plus can deactivate the screen saver - Some user operation warnings e. This command reactivates them. It is used if available connected when starting playback, otherwise the system default device is used.

In addition to the iZotope filter settings, the sigma-delta modulation filter can be chosen. To avoid DSD upsampling clipping issues leading to silence , the volume of too loud tracks must be reduced.
For tracks with ReplayGain and sample peak values, the need and the amount of volume reduction is computed automatically. For others, a fixed amount of safe volume reduction can be specified here. Audio Signal Polarity These options give the ability to invert globally the polarity of the audio signal, either for all tracks, or for only the tracks that have the invertpolarity keyword in their comments. Volume control type Your DAC may or may not offer remote volume control master or digital.
Thus a dithering algorithm is used to lessen the audible impact of this digital volume control.

Use this setting for this purpose. This avoids the common problem of having to manually adjust volume levels between tracks when playing audio files from albums that have been mastered at different loudness levels. To remove the need to manually adjust the volume of the preamplifier, the volume leveling can be performed automatically to a normalized value of average loudness of dB. These settings allow to switch on this automated loudness volume normalization during playback at the album or individual track level.
Then select in the drop down lists the Audio Units you want to use. Configuration of each Audio Unit plugin can be done either offline by clicking on Configure Click on Apply when done with the settings to save them. Presets for each Audio Unit type can be saved or recalled.

The automated detection of iDevices on USB can even cause audible clicks. It is therefore strongly advised to enable SysOptimizer. It will deactivate these interfering background services at playback start, and reactivate them upon stop.
In addition, SysOptimizer can increase the priority of Audirvana Plus during playback to maximize the precision of the audio streaming. There are two ways to do this import:.
This is the recommended method, as any folder content update will then be automatically pushed to Audirvana Plus except for the network volumes. Adding new files inside these folders will make their tracks automatically appear in Audirvana Plus. In case of synchronization conflict, the priority is given to changes made in Audirvana Plus over in iTunes. The tracks that are also in folders in the synchronization list will be preserved. Note that this operation will need to be repeated each time the iTunes library is updated.
The following information is not synchronized from iTunes: - Tracks not readable outside of iTunes: DRM protected files usually ending with. Tracks whose file is not accessible during the synchronization will not be imported. If you have a streaming account, you can connect it by clicking on « Connect ».
Example for Qobuz given below:. For best sound quality, Audirvana Plus can completely deactivate sound playback by iTunes. Note that this also prevents any other application to output sound during playback. In addition, to increase further the Sound Quality, you can deactivate convenience functions: - Volume Control: Audirvana Plus interacts with iTunes on a regular basis to exchange the volume control values.
