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.

Processing is performed by the player application and the processed data is then asynchronously streamed over network to a very lightweight network audio adapter interfacing to the DAC. Network Audio Adapter Network audio is especially useful to give freedom from cables when player is run on a tablet or other wireless device. Incredibly low processor latency (average 2-6 microseconds on fairly powerful processors) Boot time 10/15 s. Audio latency at 44.1 kHz < 1 ms depending on hardware configuration. HQPlayer features several user-selectable high-quality resamplers as well as user-selectable dither/noise shaping algorithms and delta-sigma modulators. AudioLinux is the first plug & play realtime audio system based on Archlinux with programmed IRQ and application realtime priority.
#HQPLAYER MAC PRO#
Convolution engine supports RIFF (WAV) format FIR impulse responses, which can be produced with suitable software, such as Acourate, Room EQ Wizard or DRC. HQPlayer Pro is a high-quality audio file converter, recorder, and player for 64-bit Windows 7/8.1/10, macOS and Linux. For digital room correction and other equalization purposes, selectable convolution algorithms are included. 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.
