  +--lava.riff.wave.WaveSampleRounder

public class WaveSampleRounder

extends java.lang.Object

Rounds wave sample data.

Details: WaveSampleRounder is a collection of functions that round sample arrays to a desired precision.

The parameters for each of these methods follow the same pattern as described in the header for class WaveSampleConverter, with the exception that there is an additional parameter that specifies the rounding precision.

Method Detail

round

public static long[] round(long[] src,
                           int from,
                           long[] dest,
                           int to,
                           int amt,
                           int bits)

Rounds values to requested precision.

Details: round modifies the sample data so that each value is rounded to the specified number of bits. Rounding is accomplished by setting the least significant bits to 0.

Parameters:

src - source array

from - starting index in src

dest - destination array

to - starting index in dest

amt - number of values to clip

bits - number of bits of precision

Returns:

destination array

round

public static int[] round(int[] src,
                          int from,
                          int[] dest,
                          int to,
                          int amt,
                          int bits)

Rounds values to requested precision.

Details: round modifies the sample data so that each value is rounded to the specified number of bits. Rounding is accomplished by setting the least significant bits to 0.

Parameters:

src - source array

from - starting index in src

dest - destination array

to - starting index in dest

amt - number of values to clip

bits - number of bits of precision

Returns:

destination array

round

public static short[] round(short[] src,
                            int from,
                            short[] dest,
                            int to,
                            int amt,
                            int bits)

Rounds values to requested precision.

Details: round modifies the sample data so that each value is rounded to the specified number of bits. Rounding is accomplished by setting the least significant bits to 0.

Parameters:
