SetSamplingParameters ( double clock_freq, double sample_freq, double pass_freq = -1, double filter_scale = 0.97 ) : bool	Setting of SID sampling parameters. Use a clock freqency of 985248Hz for PAL C64, 1022730Hz for NTSC C64. The default end of passband frequency is pass_freq = 0.9sample_freq/2 for sample frequencies up to ~ 44.1kHz, and 20kHz for higher sample frequencies. For resampling, the ratio between the clock frequency and the sample frequency is limited as follows: 125clock_freq/sample_freq < 16384 E.g. provided a clock frequency of ~ 1MHz, the sample frequency can not be set lower than ~ 8kHz. A lower sample frequency would make the resampling code overfill its 16k sample ring buffer. The end of passband frequency is also limited: pass_freq <= 0.9*sample_freq/2 E.g. for a 44.1kHz sampling rate the end of passband frequency is limited to slightly below 20kHz. This constraint ensures that the FIR table is not overfilled.
