The RTL2832 allows to fine-tune the output frequency of the resampler by writing a correction value to a register. A call of rtlsdr_set_freq_correction() corrects both the RF frequency and the sampling frequency by calling the internal function rtlsdr_set_sample_freq_correction() which calculates a correction value and writes it to the aforementioned register.
