AudioDecoderJson Class

A decoder for json data and audio within a single data stream. Decodes the data into split audio and text streams
Meta::Voice::Audio::Decoding::AudioDecoderJson extends Meta.Voice.Audio.Decoding.IAudioDecoder.

Overview

Data Fields

int
Once setup this should display the number of channels expected to be decoded
int
Once setup this should display the number of samples per second expected
bool
Due to headers, sequential decode is required

Public Member Functions

AudioDecoderJson
( IAudioDecoder audioDecoder,
AudioJsonDecodeDelegate onJsonDecoded )
Constructor that takes in an audio decoder and decode callback delegate
void
Setup
( int channels,
int sampleRate )
Performs an audio decode setup with specified channels and sample rate
int
GetTotalSamples
( ulong contentLength )
Cannot determine total samples via content length alone
float []
Decode
( byte [] chunkData,
int chunkStart,
int chunkLength )
Performs a decode of full chunk data
