• Bit-perfect playback

    The DAC sample rate is automatically switched to the audio file original one to ensure unaltered signal is played.

    All internal processing is done using 64 bit precision to eliminate information loss due to rounding errors.

    In addition, optional processing can be configured for upsampling, volume control, and Audio Unit plugins.

  • Shortest audio signal path

    Advanced optimizations:

    • Audio device Exclusive Access
    • Direct Mode
    • Integer Mode
  • Full Memory Play

    File loading, processing, converting to DAC native format are all done before playback to minimize any possible interference

  • SysOptimizer

    SysOptimizer can be configured to stop the OS X background services potentially interfering with sound quality, and give to Audirvana Plus the extreme priority during playback to ensure the maximum signal streaming precision.

  • iZotope inside

    The world benchmark processing for:

    • 64-bit SRC best in class sample rate conversion technology
    • MBIT+ dithering Volume Control (Dithering is meant to reduce the audible impact of the inevitable reduction in the audio signal precision when reducing the bitdepth, which happens when using a digital volume control. iZotope MBIT+ is the leading technology that pushes the noise way out of the audible spectrum.)

    And these filters can be tuned precisely by configuring their advanced parameters

  • Audio Unit plug ins support

    Support huge range of Audio Unit filter plugins available on the market to allow you to pick and use your preferred equalizer, digital room correction, headphone crossover, …

  • Native DSD Streaming

    With a DSD over PCM compatible DAC, DSD64, DSD128, and beyond can be streamed natively for direct playback of the DSD signal by the DAC.

    With non DSD DACs, DSD audio files are automatically downsampled in memory to PCM before playback using a high-quality 64-bit multistage algorithm.

  • Multichannel playback

    Play in surround, 5.1 or any other channel configuration with a compatible DAC
