type converter =
| Conv_sinc_best_quality (*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%. All three Conv_sinc_* converters are based on the techniques of Julius O. Smith although this code was developed independantly.*)
| Conv_sinc_medium_quality (*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.*)
| Conv_fastest (*This is the fastest bandlimited interpolator and has an SNR of 97dB and a bandwidth of 80%.*)
| Conv_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.*)
| Conv_linear (*A linear converter. Again the quality is poor, but the conversion speed is blindingly fast.*)
Kind of converter.
