Method Detail

reSample

public byte[] reSample(byte[] sourceData,
                       int bitsPerSample,
                       int sourceRate,
                       int targetRate)

Do resampling. Currently the amplitude is stored by short such that maximum bitsPerSample is 16 (bytePerSample is 2)

Parameters:

sourceData - The source data in bytes

bitsPerSample - How many bits represents one sample (currently supports max. bitsPerSample=16)

sourceRate - Sample rate of the source data

targetRate - Sample rate of the target data

Returns:

re-sampled data
