AudioDecoderPcm Class
Extends IAudioDecoder
An audio decoder for raw PCM audio data
Fields
readonly AudioDecoderPcmType PcmType[Get]
bool WillDecodeInBackground[Get]
All pcm decoding should occur in background due to large amount of data
Member Functions
AudioDecoderPcm
( AudioDecoderPcmType pcmType,
int sampleBufferLength )
Constructor that allows selection of pcm type
virtual void Decode
( byte [] buffer,
int bufferOffset,
int bufferLength,
AudioSampleDecodeDelegate onSamplesDecoded )
A method for decoded bytes and calling an AddSample delegate for each
Parameters
buffer
A buffer of bytes to be decoded into audio sample data
bufferOffset
The buffer start offset used for decoding a reused buffer
bufferLength
The total number of bytes to be used from the buffer
onSamplesDecoded
Callback following a sample decode
Static Member Functions
static int GetByteCount
( AudioDecoderPcmType pcmType )
Returns total bytes per sample
static long GetTotalSamplesPcm
( long contentLength,
AudioDecoderPcmType pcmType )
Gets pcm sample count from byte content length (1 sample = 2 bytes)
Parameters
contentLength
The provided number of bytes
static float [] DecodePcm
( byte [] rawData,
AudioDecoderPcmType pcmType )
Decodes an array of pcm data
Parameters
rawData
Raw array of pcm bytes
pcmType
The pcm decode type to be used
static float DecodeSample_Pcm16
( byte [] rawData,
int index )
Decodes an Int16 sample into a float from 0 to 1
Parameters
rawData
Raw data to be decoded into a single sample
index
Offset of the data
static float DecodeSample_Pcm32
( byte [] rawData,
int index )
Decodes an Int32 sample into a float from 0 to 1
Parameters
rawData
Raw data to be decoded into a single sample
index
Offset of the data

( byte [] rawData,
int index )
Decodes an Int64 sample into a float from 0 to 1
Parameters
rawData
Raw data to be decoded into a single sample
index
Offset of the data
static float DecodeSample_PcmU16
( byte [] rawData,
int index )

Object Data for package-func
delegate float PcmDecodeDelegate
( byte [] buffer,
int bufferOffset )
Decodes a specific buffer index
Object Data for package-static-func
static PcmDecodeDelegate GetPcmDecoder
( AudioDecoderPcmType pcmType )
Returns a decode method depending on the pcm type
