Method Detail

max

public static double max(double[] dataIn)

Returns:

the max value of a double array. Assumes the wave form is centred around zero.

normalize

public static void normalize(SampleSet input,
             int percentage,
             javax.sound.sampled.AudioFormat format)

Normalizes the input SampleSet according to its sample size i.e. 8-bit 16-bit etc and the percentage of amplitude within this sample size. e.g. if percentage = 100 and the sample size is 8 bits then the max value of the sample set will be 127.

normalizeTo16Bit

public static void normalizeTo16Bit(SampleSet input)

Noramlizes to 16-bit resolution to 90% of the bandwidth
