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.
