Selectable algoritm and noise filters for DSF/DSDIFF PCM playback (13 / 12 options).Playback of DSF/DSDIFF files through any supported audio interface (PCM conversion and DSD rate conversion).Source content analysis to detect need for apodizing oversampling filter.Software-based digital volume control for PCM and SDM (DSD).Parametric equalizers for PCM/DSD content.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 (9 options).Delta-Sigma modulators for upsampling PCM/DSD content up to 98.304 MHz 1-bit SDM (14 modulators, 49 PCM oversampling options and 3 DSD rate converters).Software upsampling / downsampling with selectable algorithm up to 32-bit 1.536 MHz or down to 8-bit 32 kHz PCM (45 options, most “apodizing”).The main features of HQPlayer Desktop are: Convolution engine supports RIFF (WAV) format FIR impulse responses, which can be produced with suitable software. Want to buy 192/24 or DXD files for future but currently own only 96/24 capable hardware? Or want to buy DSD128 or DSD256 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.įor digital room correction and other equalization purposes, selectable convolution algorithms are included. 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 macOS.
