An audio decoder for raw MPEG audio data
Meta::Voice::Audio::Decoding::AudioDecoderMp3 extends Meta.Voice.Audio.Decoding.IAudioDecoder.

Overview

Data Fields

bool
Mp3 must be decoded sequentially in since frame data could be carried over to the next chunk

Public Member Functions

void
Setup
( int channels,
int sampleRate )
Initial setup of the decoder
int
GetTotalSamples
( ulong contentLength )
Mp3 sample count cannot be determined from content length, return -1
float []
Decode
( byte [] chunkData,
int chunkStart,
int chunkLength )
A method for returning decoded bytes into audio data
