Differentiation is precisely what you don't want a chopper to do. When the chopper's on, you want the signal grounded out, when it's not, you want raw, undistorted signal.
A capacitor certainly doesn't isolate it, in any case. It has to be charged up by the input signal, the larger the value, the harder it sucks on it. You're putting your signal, input and output, through a fairly brutal low pass filter.
If the chopper is distorting the input, your input resistance of 1K may be too low.

mlib_status mlib_SignalLimit_F32S(mlib_f32 *srcdst, const mlib_f32 *low, const mlib_f32 *high, mlib_s32 n);
DESCRIPTION
Each of these functions performs hard limiting.
For monaural signals, the following equation is used:
dst[i] = low[0] if src[i] < low[0]
dst[i] = src[i] if low[0] <= src[i] < high[0]
dst[i] = high[0] if src[i] >= high[0]
where i = 0, 1, ..., (n - 1).
For stereo signals, the following equation is used:
dst[2*i] = low[0] if src[2*i] < low[0]
dst[2*i] = src[2*i] if low[0] <= src[2*i] < high[0]
dst[2*i] = high[0] if src[2*i] >= high[0]
dst[2*i+1] = low[1] if src[2*i+1] < low[1]
dst[2*i+1] = src[2*i+1] if low[1] <= src[2*i+1] < high[1]
dst[2*i+1] = high[1] if src[2*i+1] >= high[1]
where i = 0, 1, ..., (n - 1).
PARAMETERS
Each of the functions takes some of the following arguments:
dst Destination signal array.
src Source signal array.
srcdst Source and destination signal array.
low Lower input limit. In the stereo version, low[0] contains the lower limit for channel 0, and low[1] contains the lower
limit for channel 1.
high Upper input limit. In the stereo version. high[0] contains the upper limit for channel 0, and high[1] contains the upper
limit for channel 1.
n Number of samples in the source signal array.
RETURN VALUES
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
