特性:

• Software upsampling / downsampling with selectable algorithm up to 32-bit 1.536 MHz or down to 16-bit 32 kHz PCM (14 options, most "apodizing")
• Delta-Sigma modulators for upsampling PCM/DSD content up to 24.576 MHz 1-bit SDM (6 oversampling options)
• Selectable dithering / noise shaping algorithm (7 options)
• Selectable convolution algorithm (FIR) for equalization, such as digital room correction (2 options), for PCM/DSD content
• Optional high-frequency expansion for the convolution engine
• Software-based digital volume control for PCM and SDM (DSD)
• Playback of DSF/DSDIFF files through any supported audio interface (PCM conversion and 128x to 64x conversion)
• Selectable algoritm and noise filters for DSF/DSDIFF PCM playback (7 / 6 options)
• Native/direct playback of DSF/DSDIFF files (ASIO DSD, DoP v1.1 with both 0x05/0xFA and 0x06/0xF9 markers)
• Playback of stereo, 2.1, 3.0, quadrophonic, 3.1, 5.0, 5.1 and 7.1 channel material
• Speaker configuration for multichannel playback (delay and level) for PCM and SDM (DSD)
• Bypasses operating system software mixer and sample rate conversion
• Support for professional ASIO drivers
• Multi-room support with Signalyst Asynchronous Network Audio Adapters
• Support for ID3v2 tags on AIFF, DSF and WAV files (versions 2.2, 2.3 and 2.4)
• Smooth level limiter for clipped material
• "Dual wire" channel bonding support to reach 2x rates, PCM and DoP (DSD)
• 64-bit floating point processing
• Full support for multi-core processors (can utilize up to around 27 cores depending on configuration)
• Light weight desktop-GUI to lower graphics noise
• Touch-GUI for use with tablets or laptops with touch screen.
