Class TimeBase

java.lang.Object

artisynth.core.util.TimeBase

public class TimeBase
extends java.lang.Object

Converts between basic Artisynth time units (ticks) and seconds, milliseconds, microseconds, and frequency. The basic time tick is a sub-nanosecond quantity chosen to allow the time intervals associated with standard audio frequencies (i.e., 48kHz, 44.1khz, 32khz, etc.), as well as those which are multiples of 1 microsecond, to be represented as long integers.

Method Detail

round

public static double round(double t)

Rounds t to the nearst PRECISION seconds.

Returns:

rounded value of t.

equals

public static boolean equals(double t0,
                             double t1)

Returns true if t0 and t1 are equal within the tolerance specified by PRECISION.

Returns:

true if t0 and t1 are equal within tolerance

modulo

public static double modulo(double t0,
                            double t1)

Returns t0 modulo t1, within the tolerance specified by PRECISION.

Returns:

t0 % t1 within PRECISION.

compare

public static int compare(double t0,
                          double t1)

Compares t0 and t1 within the tolerance specified by the reciprocal of PRECISION. Returns an integer which is less than, equal, or greater than 0 if t0 is less than, equal, or greater than t1.

Returns:

integer comparing t0 and t1

main
