HQPlayer is a high quality audio player for Windows, Linux and macOS. HQPlayer also features several selectable high quality upsampling and downsampling algorithms as well as selectable dither, noise shaping and modulator algorithms.

All modern DACs employ oversampling and delta-sigma modulation, however the hardware implementations are more or less resource constrained. Higher quality oversampling and delta-sigma modulation can be done by utilizing vast mount of processing power available in modern PCs. Many AVRs also resample internally to 48, 96 or 192 kHz, with the HQPlayer, these can be fed at the native rate.

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.

Windows 10 x64

Audio interface with support for WASAPI Exclusive or ASIO

CPU support for SSE4.2 instruction set

Display adapter with OpenGL support

Minimum full-HD resolution (1080p)

PDF reader software

Improve Direct SDM indication towards clients, support relative paths in playlist files, add invert, random and repeat functions to the Client. Number of small improvements and fixes.
