HQPlayer Quick Start Guide


This is so called transport list, AKA library. You can configure the contents using File / Library... menu entry. You can select two kinds of entries from this list. Main one is "transport", highlighted here, which is an entire subdirectory (or a CD-drive). Transport usually equals to an album based on commonly used artist/album/song layout. Another is a single file - usually a song. Selecting a song changes playback mode to playlist mode, you can add more tracks by selecting more tracks or by drag-and-drop from outside of the application*. Direct DSDIFF/DSF playback is possible only in transport mode or when playlist contains only DSDIFF and/or DSF files, when playlist contains also other supported file types PCM conversion is used. Current mode is indicated in the status bar area, after each selection.

Tracks or playlist

This is the list of tracks in transport mode or list of songs in a playlist mode. If you selected a directory in the list above, it is in a transport mode. If you selected a song, or used drag-and-drop, it is in a playlist mode.


This is where you can select how the output is produced. Output is always at the maximum bit depth of your audio interface at the sampling rate selected here. Regardless of source. You should always use at least TPDF dither. Bit depth can be changed from the File / Settings menu and should match that of DAC's, or it's linear range in case you have measurements available.

First select output sample type from right (PCM/DSD). Then follow order of the settings from left to right; resampling/oversampling algorithm, dither/noise-shaping algorithm and output sampling rate.

Direct DSDIFF/DSF playback

This is how things look like when direct DSDIFF/DSF playback mode has been engaged for capable hardware by selecting, in this case, a DSF transport. Notice that the filter/dither/convolution settings are disabled and that the output sampling rate selection displays full rate. No processing is performed in this mode.
