All modern DACs employ oversampling anddelta-sigma modulation, however the hardwareimplementations are more or less resourceconstrained. Higher unique oversampling anddelta-sigma modulation can be done byutilizing vast mount of processing poweravailable in modern PCs.Many AVRs also resample internally to48, 96 or 192 kHz, with the HQPlayer,these can be fed at the native rate.
Want khổng lồ buy 192/24 or DXD files for futurebut currently own only 96/24 capable hardware?Or want to lớn buy DSD128 or DSD256 files butcurrently own only DSD64 or 192/24 PCM capablehardware?Resampling and dither/noise shaper can beused to playbaông xã high resolution files on alower resolution hardware, allowingfuture-proof investmenton high resolutionfiles.
For digital room correction & otherequalization purposes, selectable convolutionalgorithms are included.Convolution engine supports RIFF (WAV) formatFIR impulse responses, which can be producedwith suitable software, such asAcourate,Room EQ Wizard + rePhase,Audiolense,orDRC.
Network Audio Adapter
Network audio is especially useful togive freedom from cables when player is runon a tablet or other wireless device.

Processing is performed by the playerapplication và the processed data is thenasynchronously streamed over network to avery lightweight network audio adapterinterfacing khổng lồ the DAC. Asynchronous FIFOprovides maximum isolation between processingvà audio reproduction.
