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 is especially useful to give freedom from cables when player is run on a tablet or other wireless device. Convolution engine supports RIFF (WAV) format FIR impulse responses, which can be produced with suitable software, such as Acourate, Room EQ Wizard or DRC. 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. 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. All modern DACs employ oversampling and delta-sigma modulation, however the hardware implementations are more or less resource constrained. Kysyttäessä käytännön esimerkkiä tarkentaa Laako vielä, että aika monet ajavat HQPlayeria pctai Mac-koneissa, mahdollisesti Roonin rinnalla, jolloin (LinQin) pelkkä NAA-moduuli on kätevä. HQPlayer also features several selectable high quality upsampling and downsampling algorithms as well as selectable dither, noise shaping and modulator algorithms. Monimutkaisempiin huonekorjauksiin ja vastaaviin prosesseihin saattaa ulkoinen HQPlayer ja pelkkä NAA-moduuli olla parempi vaihtoehto. HQPlayer is a high quality audio player for Mac OS X.
