jpg, cover. jpg image file in the same folder as the audio file - The first file found ending with Sleeve. jpg, or the first file found with the. jpg extension in the same folder as the audio file. 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. Playlists opEons - M3U playlist format can be interpreted like M3U8, that is with UTF-8 character encoding. 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. com server to check if an updated version is available, and propose to download it. Miscellaneous opEons - During playback, Audirvana Plus can deactivate the screen saver - Some user operation warnings e. delete tracks from library can be deactivated. This command reactivates them. SelecEng the Audio Device Audirvana Plus uses a hot plugging mechanism: you select your preferred Audio Device.
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.
MQA Device MQA devices decoder or renderer are automatically detected. You then have the possibility to set manually if it is a MQA decoder or MQA renderer.
When a MQA track is played, any audio processing after the MQA decoding upsampling, audio units, software volume control, … is disabled to send an authenticated MQA signal to the DAC. Even more, for MQA decoders, the signal is not decoded in Audirvana Plus. Simple Decimation the algorithm used before version 1. system beeps, …. Direct Mode: In this mode Audirvana Plus bypasses completely CoreAudio, including its low-level layers.
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. More information in Audirvana: OSX Bit Perfect and Integer Mode.
Audio buffers memory allocaEon Set the maximum amount of memory Audirvana Plus can use for loading the audio tracks in memory. 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. the advanced synchronization locking of the AMR DP may need up to 4s. 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.
MulEchannel 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. Sample Rate Conversion Sample Rate Conversion happens when - The audio device does not handle the audio track sample rate - Upsampling is forced.
Two different Sample Rate Converter algorithms are proposed: the standard Apple CoreAudio, or the gold standard iZotope bit SRC. 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. 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. the highest available on the audio device of 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. 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. 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 approximately 14 dB of audible noise suppression, at the expense of a higher noise floor.
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. USB may be higher than the one the DAC can handle, or even the DAC linear range may be in a lower bit depth 20bit instead of 24bit. 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. 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.
Select Use AudioUnits effects to enable the Audio Units plugins support. 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. 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.
m4p extension , the tracks on the cloud and coming from Home Sharing libraries - Non musical tracks e. video, books - Criteria of Smart Playlists, only the tracks are imported for these The following information is not synchronized to iTunes: - Advanced metadata not handled by iTunes e.
soloist, conductor, period - Play count and last played date - Playlists single way: only imported from iTunes, any changes done to these playlists imported from iTunes in Audirvana Plus is erased upon the subsequent synchronization In addition, with this method, you need to ensure all your music files folders are accessible mounted before launching the synchronization.
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.
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. The DAC name shall appear under Active Audio Device. 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.
A workaround consists in plugging the DAC in a USB powered hub that is connected to the Mac. 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.
Enable SysOpEmizer Enable SysOptimizer in the User Preferences to have more advanced optimizations performed automatically at each playback. Set priority to Extreme. DeacEvate screen saver Using the option in the General page of Audirvana Plus preferences Disable energy saver In System Preferences, Energy Saver, set the Computer Sleep and the Display Sleep time to Never.
