Class Conversions

java.lang.Object

eu.bandm.sig.adlib.Conversions

public class Conversions
extends Object

Library of conversion routines between representations of sound signals. All methods are static and work between a "semantic" data type and sequences of bytes, "decoding" from the former to the latter, "encoding" vice versa.
The method signatures can be used to "walk over" a larger array of bytes, or applied to a temporary buffer for just one sample.

pcmSigned16BigEndian_float_to_raw

public static void pcmSigned16BigEndian_float_to_raw(float x,
                                                     byte[] out,
                                                     int outindex)

(Copied from bt's code in DataLineSink)

Parameters:

pcm - the sound sample to convert

out - where to store the byte results

outindex - where to store the byte results
