Enum Constant Detail

LINEAR_INTERPOLATION

public static final SampleRateConverter.SampleRateConversionAlgorithm LINEAR_INTERPOLATION

Performs linear interpolation between samples where the sample rate in the output format is greater than the sample rate of the input format. If the sample rate is less, then the nearest value of the input samples is used.

sbout

protected SampleBuffer sbout

Method Detail

values

public static SampleRateConverter.SampleRateConversionAlgorithm[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (SampleRateConverter.SampleRateConversionAlgorithm c : SampleRateConverter.SampleRateConversionAlgorithm.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static SampleRateConverter.SampleRateConversionAlgorithm valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

process

public abstract SampleChunk process(SampleChunk s,
                                    AudioFormat output)

Process a sample chunk and output a sample chunk in the given output format.

Parameters:

s - The input sample chunk

output - The output format

Returns:

A resampled sample chunk.
