    I created PCM file (176.4 kH, 16 bit), then I converted it to DSD using Weiss Saracon, then converted DSD to PCM using foo_input_sacd in two modes: Multistage (Fixed-Point) and Multistage (Double-Precision).
    On waveform of resulted files it is clearly seen, that Multistage (Fixed-Point) gives phase inversion. Here are waveforms:
    Original PCM:

    DSD to PCM in Multistage (Double-Precision) mode:

    DSD to PCM in Multistage (Fixed-Point) mode:
    Fixed-Point
