It looks familiar.
Regardless of the size or location of your music library, let Audirvana know where to find it. Then you can navigate it using an easy and elegant user interface, organize it as you wish, and create playlists.
Libraries and Playlists
It’s simple. Audirvana is an open platform that accepts all formats used by our most demanding customers — FLAC, MQA, DSD, Apple Lossless, AIFF, WAV — but also M4A, MP3, WavPack, Cue Sheets, or APE.
Audio File Formats
To help you fully enjoy your music, Audirvana offers a universal service that supports all the formats you need so you can play your audio files without having to modify or downgrade them. There are two main families of digital audio formats Pulse Code Modification (PCM) and Direct Stream Digital (DSD).
The PCM protocol is by far the most widely used in computers. It is supported natively by computers and describes each sample in absolute value independently of the previous ones. It is the basis of the WAV format, or Apple’s AIFF, which includes metadata. Depending on the clock used to digitize a PCM file, it can have 44,100 or 48,000 samples per second (or multiples of these values: 88.2 kHz, 176.4kHz, 96kHz, 192kHz, etc.). Each value is quantified on a scale of ±32,767 (signed 16-bit binary code encoding). With 24bits, we have more values reproduce more subtly the dynamics nuances, but the speed and size of the files increase. The CD or Red Book format, for example, contains a 44.1kHz sampling rate with 16 bits in stereo, i.e. a bit rate of 1,411 kb per second (1,411k = 44100 x 16 x 2). Beyond that are the High Resolution (HiRes), or High Definition (HD) or Studio Master formats.
To accommodate large sampling rates, including the file sizes, and storage space they require, compression formats have been developed that allow the transmitter-side signal to be encoded and then decoded during playback, hence the expression CODEC (coding and cecoding contraction). Compression may be lossless ( FLAC, Apple Lossless–ALAC, WMA Lossless, WavPack, and APE formats). Or it may be lossy, with the deletion of minor audio data supposed masked by more dominant data , and with data rates often between 128 kbps and 320 kbps, i.e. between 10 and 4 times less data than the CD format (MP3, WMA, AAC, etc.).
Audirvana was the first application in its category to integrate MQA (Master Quality Authenticated), a more recent PCM format that reproduces studio-master audio quality in a file small enough to be streamed or downloaded. Using a DAC with the “MQA decoder” maximizes MQA quality. If your DAC is an “MQA renderer,” decoding is shared between application and DAC, guaranteeing the same optimal quality. Finally, even if your DAC is not MQA-compatible, it can still read the files, and you benefit from their high resolution, especially from a two-fold sampling.
DSD is a protocol developed by Sony and Philips. It is based on binary encoding of sound at a very high sampling rate that is 64 to 128 times that of the CD. It thus offers very good impulse response. The code can have only two values: +1 (if the signal goes up) or -1 (if the signal goes down). Thus the pulse durations determine the amplitude of the signal (Pulse Density Modulation). Audirvana allows you to decode and read all your DSD files, as well as SACD disc ISO images. The ASIO driver on Windows supports the DSD format unlike the WASAPI driver and macOS. This is why Audirvana uses in the latter cases the “DSD over PCM” protocol, which passes a native DSD signal in what the OS believes to be PCM. However, this limits the maximum usable sampling frequency.
Your Ideal Library
Prioritizing sound quality, Audirvana technology offers unlimited access to high-resolution music libraries, accessible from the same interface, and played using the best methods. Our partners — TIDAL (with Master MQA), Qobuz (Studio Master), HRA Streaming — offer quality superior to the CD format with exclusive advantages.
Hi-Res Streaming Services
Tidal Tidal is an American streaming service, available in 52 countries, which offers more than 60 million songs.The service offers high-fidelity, CD-quality music, and high resolution video. The Audirvana license provides two additional TIDAL free discovery months if you subscribe to the HiFi tier (offer reserved for new TIDALsignups).
Qobuz originated in France and has become available in about 15 countries including the U.S. since 2019. It offers 40 million titles in CD quality, with an extensive classical repertoire, and nearly 200,000 albums in high-res audio quality. The acquisition of the Audirvana license entitles you to two additional Qobuz free discovery months if you subscribe to the HI-FI offer (reserved for new Qobuz users, not yet available in the U.S.).
HRA-Streaming is thestreamingservice of HighResAudio, a German download site that offers more than 30,000 albums specially selected for their recording quality and whose high-definition quality is 100 percent verified.
Match your speakers
To optimize the listening experience, Audirvana enables you to set up the audio stream in accordance with your audio system’s digital-to-analog converter (DAC). This is done automatically if you use headphones to listen on your computer, or if you use an external sound card connected via USB. Otherwise, Audirvana connects wirelessly to your system using the universal network protocol UPnP/DLNA and decodes stereo or multi-channel files.
You can also simply send the sound to your speakers via Bluetooth or Airplay (Mac).
When choosing the system on which Audirvana will play your music, you select the digital-to-analog converter (DAC) that will transform the digital data into an analog electrical signal that will drive your speakers. The DAC is a key element in sound quality. For example, if you listen through your computer’s headphone jack, you use the DAC in the computer, called the “integrated output.” If you send the sound to an external device, the signal is transmitted digitally to that device and converted to analog by it.
Depending on its quality, the DAC is more or less accurate, able to support certain formats or high resolutions, and to perform consistent calculations in real time such as oversampling.
The default settings are generally satisfactory, but to optimize the sound quality of your system, regardless of file formats, make sure that Audirvana has the technical information about your DAC. You may specify whether or not it supports the DSD or MQA formats, the maximum sampling rate, and the resolution allowed. Thus, Audirvana will enable you to get the best out of your DAC by transmitting adapted and already decoded information, which will limit the computer processing to what is strictly necessary.
Almost all DACs on the market today operate on a very high frequency switching principle with a resolution of only a few bits. They therefore systematically oversample the signal, but work with limited computing power and more or less efficient algorithms. You can ask Audirvana to perform this operation upstream, using the significantly higher computing capabilities of the computer and with a high-performance algorithm (SoX).
To send music to your wireless system without any loss in quality, Audirvana works with the universally accepted UPnP or DLNA protocol. It is a royalty-free protocol that allows multiple devices to communicate over the same network (wirelessly over wi-fi or wired over ethernet or PLC) to share and play files, including audio.
In this configuration, what DLNA refers to as a “media renderer,” which converts and plays the music, will retrieve the files on a “media server” using a control point, typically your computer. To be able to decode files in advance, Audirvana plays the roles of control point and ad hoc media server. In other words, it is seen by the renderer as the file provider, which allows it to perform the necessary processing.
Stay Up To Date
Since 2011, Audirvana has been evolving constantly, integrating new formats, adding new features, and improving the user experience. It is now also available on Windows 10. Free updates are available for macOS version 3.5 with a brand-new user interface. If you’re already using Audirvana, get major upgrades (new series) at a preferred price.
If you want to use room correction, Audirvana offers external filters (AudioUnits or VST3) that apply room correction settings to all music.
The use of an external filter, or audio plug-in, modifies the frequency response of all songs played. This can be useful to correct room resonance, change the signature of an audio system, or apply a specific effect. Audirvana can integrate AudioUnits under macOS, or VST3 under Windows, into the signal processing chain. Set the compatible filters of your choice and apply them to all songs played in Audirvana. These settings should be carefully used and are not for everyone. They require expertise to avoid creating greater nuisances than those you were trying to correct in the first place.
You needn’t be tethered to your computer. You can control Audirvana remotely from your smartphone by downloading the A+ Remote mobile application from the App Store.
Note that these are remote controls: Audirvana continues to work directly through your computer to ensure optimal sound. Our technologies cannot be implemented under iOS or Android.
