![]() 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.
