HQPlayer is a high quality audio player for Windows, Linux and macOS. HQPlayer also features several selectable high quality upsampling and downsampling algorithms as well as selectable dither, noise shaping and modulator algorithms.

All modern DACs employ oversampling and delta-sigma modulation, however the hardware implementations are more or less resource constrained. Higher quality oversampling and delta-sigma modulation can be done by utilizing vast mount of processing power available in modern PCs. Many AVRs also resample internally to 48, 96 or 192 kHz, with the HQPlayer, these can be fed at the native rate.

Features:

Software upsampling / downsampling with selectable algorithm up to 32-bit 1.536 MHz or down to 8-bit 32 kHz PCM (28 options, most "apodizing")
Delta-Sigma modulators for upsampling PCM/DSD content up to 98.304 MHz 1-bit SDM (11 modulators, 30 PCM oversampling options and 2 DSD rate converters)
Selectable dithering / noise shaping algorithm (9 options)
Selectable convolution algorithm (FIR) for equalization, such as digital room correction (2 options), for PCM/DSD content
Optional high-frequency expansion for the convolution engine
Software-based digital volume control for PCM and SDM (DSD)
Playback of DSF/DSDIFF files through any supported audio interface (PCM conversion and DSD rate conversion)
Selectable algoritm and noise filters for DSF/DSDIFF PCM playback (11 / 8 options)
Native/direct playback of DSF/DSDIFF files (ASIO DSD, DoP v1.1 with both 0x05/0xFA and 0x06/0xF9 markers)
Playback of stereo, 2.1, 3.0, quadrophonic, 3.1, 5.0, 5.1 and 7.1 channel material
Speaker configuration for multichannel playback (delay and level) for PCM and SDM (DSD)
Matrix processing for routing, filtering and mixing channels with gain, for PCM/DSD content
Bypasses operating system software mixer and sample rate conversion
Support for professional ASIO drivers
Network endpoint support with Signalyst Asynchronous Network Audio Adapters
Support for ID3v2 tags on AIFF, DSF and WAV files (versions 2.2, 2.3 and 2.4)

can someone tell me what's the point of oversampling a finished song done and processed at 44.1/48khz? Plenty of smoke and mirrors in the audophile world.

you should spend some time playing with the settings to get the best results. Oversampling might be good or bad depending on how you use it. There's a lot of articles about it.

you can't improve the quality of something already printed, you don't add any information, only duplicate already existing one. In mixing/processing is used to increase aliasing distortion tollerance from nonlinear processes. You can't take a flac file or any kind of file compressed and uncompressed, play it oversampled and that magically sounds better. As well DSD is nonsensical since for the 99.999% (and probably even more decimal 9s) the music is recorded, processed and done in pcm in first place.
