DSF to DFF converter

Key features

Sample rates: D64, D128, D256, D512, D1024
Output band (by user option): 20 kHz (optimized mode, recommended); up to 100 kHz (wide band mode).

Audio quality issues

In Settings > General 3 main filter modes that define output band:

Optimized mode (20 kHz output audio band; recommended);
Non-optimized (up to 24 kHz, depend on input and output sample rates);
Non-optimized Wideband (up to 100 kHz, depend on input and output sample rates).

If modes #2 and #3 cause audible noise at your hardware, then use mode #1.

You can compare sound (see Settings > General > "Use minimum phase filter" switch). When the switch is checked in Optimized mode (#1) "quasi-analog filter" is applied. In modes #2 and #3 the switch is ignored.

If you want to copy input DSF to output DFF without any processing (bit-perfect conversion):

in Settings > General > check "Don't make DSP..." switch;
in main window > Output panel > Sampling rate list choose "as input" or sample rate value similar to input file.
