-       best: This is a bandlimited interpolator derived from the
-       mathematical sinc function and this is the highest quality
-       sinc based converter, providing a worst case Signal-to-Noise
-       Ratio (SNR) of 97 decibels (dB) at a bandwidth of 97%.
-
-       medium: This is another bandlimited interpolator much like the
-       previous one. It has an SNR of 97dB and a bandwidth of 90%. The
-       speed of the conversion is much faster than the previous one.
-
-       fastest: This is the fastest bandlimited interpolator and
-       has an SNR of 97dB and a bandwidth of 80%.
-
-       zero_order_hold: A Zero Order Hold converter (interpolated
-       value is equal to the last value). The quality is poor but
-       the conversion speed is blindlingly fast.
-
-       linear: A linear converter. Again the quality is poor, but
-       the conversion speed is blindingly fast.
