Multi-room support with Signalyst Asynchronous Network Audio Adapters Speaker configuration for multichannel playback (delay and level) for PCM and SDM (DSD)īypasses operating system software mixer and sample rate conversion Playback of stereo, 2.1, 3.0, quadrophonic, 3.1, 5.0, 5.1 and 7.1 channel material Native/direct playback of DSF/DSDIFF files (ASIO DSD, DoP v1.1 with both 0x05/0xFA and 0x06/0xF9 markers) Selectable algoritm and noise filters for DSF/DSDIFF PCM playback (7 / 6 options) Playback of DSF/DSDIFF files through any supported audio interface (PCM conversion and 128x to 64x conversion) Software-based digital volume control for PCM and SDM (DSD)
Optional high-frequency expansion for the convolution engine Selectable convolution algorithm (FIR) for equalization, such as digital room correction (2 options), for PCM/DSD content Selectable dithering / noise shaping algorithm (7 options) 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")ĭelta-Sigma modulators for upsampling PCM/DSD content up to 24.576 MHz 1-bit SDM (6 oversampling options) Want to buy 192/24 files for future but currently own only 96/24 capable hardware? Or want to buy DSD128 files but currently own only DSD64 or 192/24 PCM capable hardware? Resampling and dither/noise shaper can be used to playback high resolution files on a lower resolution hardware, allowing future-proof investment on high resolution files. Many AVRs also resample internally to 48, 96 or 192 kHz, with the HQPlayer, these can be fed at the native rate. Higher quality oversampling and delta-sigma modulation can be done by utilizing vast mount of processing power available in modern PCs. HQPlayer also features several selectable high quality upsampling and downsampling algorithms as well as selectable dither, noise shaping and modulator algorithms.Īll modern DACs employ oversampling and delta-sigma modulation, however the hardware implementations are more or less resource constrained. HQPlayer is a high quality audio player for Windows, Linux and Mac OS X.
