HQPlayer Desktop 5.5.1 (x64)

HQPlayer Desktop 5.5.1 is a standalone audio player for Windows x64, built for high-resolution listening and configurable playback processing rather than use as a VST plugin. It suits hobby producers and audio enthusiasts who want control over how stereo or multichannel files reach their DAC or audio interface.

Its resampling engine offers selectable upsampling and downsampling filters, alongside dithering, noise shaping and delta-sigma modulation for PCM and DSD material. This lets you adapt high-resolution recordings to the rates your playback hardware supports. DSF and DSDIFF files can be converted for PCM playback or sent through supported native DSD and DoP paths.

For more involved listening setups, HQPlayer includes FIR convolution for EQ or room correction, channel routing and mixing, plus speaker delay and level adjustment. Playback supports layouts up to 7.1, while ASIO support allows the application to bypass the Windows software mixer and sample-rate conversion. Multicore processing and optional NVIDIA CUDA DSP offload help handle demanding conversion tasks. It is a dedicated listening utility, not an effect to insert into FL Studio or Ableton Live.
