public static int bytesToInt16(byte[] buffer, int byteOffset, boolean bigEndian)
byteOffset
in
buffer
to a signed integer sample with 16bit range.
For little endian, buffer[byteOffset] is interpreted as low byte, whereas it is interpreted as high byte in big endian.
This is a reference function.
public static int bytesToInt24(byte[] buffer, int byteOffset, boolean bigEndian)
byteOffset
in
buffer
to a signed integer sample with 24bit range.
For little endian, buffer[byteOffset] is interpreted as lowest byte, whereas it is interpreted as highest byte in big endian.
This is a reference function.
public static int bytesToInt32(byte[] buffer, int byteOffset, boolean bigEndian)
byteOffset
in
buffer
to a signed 32bit integer sample.
For little endian, buffer[byteOffset] is interpreted as lowest byte, whereas it is interpreted as highest byte in big endian.
This is a reference function.
public static short ulaw2linear(byte ulawbyte)
public static byte linear2ulaw(int sample)
public static short alaw2linear(byte ulawbyte)
public static byte linear2alaw(short pcm_val)
public static void intToBytes16(int sample, byte[] buffer, int byteOffset, boolean bigEndian)
int
to 2 bytes in an array.
sample
is interpreted as signed (as Java does).
For little endian, buffer[byteOffset] is filled with low byte of sample, and buffer[byteOffset+1] is filled with high byte of sample + sign bit.
For big endian, this is reversed.
Before calling this function, it should be assured that
sample
is in the 16bit range - it will not be clipped.
This is a reference function.
public static void intToBytes24(int sample, byte[] buffer, int byteOffset, boolean bigEndian)
int
to 3 bytes in an array.
sample
is interpreted as signed (as Java does).
For little endian, buffer[byteOffset] is filled with low byte of sample, and buffer[byteOffset+2] is filled with the high byte of sample + sign bit.
For big endian, this is reversed.
Before calling this function, it should be assured that
sample
is in the 24bit range - it will not be clipped.
This is a reference function.
public static void intToBytes32(int sample, byte[] buffer, int byteOffset, boolean bigEndian)
int
to 4 bytes in an array.
sample
is interpreted as signed (as Java does).
For little endian, buffer[byteOffset] is filled with lowest byte of sample, and buffer[byteOffset+3] is filled with the high byte of sample + sign bit.
For big endian, this is reversed.
This is a reference function.
