HQPlayer Desktop 5.4.2 [Latest]

February 5, 2024

HQPlayer Desktop - is a high quality audio player for Windows. 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.

Features
• Software upsampling / downsampling with selectable algorithm up to 32-bit 1.536 MHz or down to 16-bit 32 kHz PCM (25 options, most "apodizing")
• Delta-Sigma modulators for upsampling PCM/DSD content up to 49.152 MHz 1-bit SDM (24 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 DSD rate 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)
• Matrix processing for routing, filtering and mixing channels with gain, for PCM/DSD content
• Bypasses operating system software mixer and sample rate conversion
• Support for professional ASIO drivers
