Detailed Description

class for de-compressing audio received from network

This class encapsulates opus decoder for packing audio over network.

Constructor & Destructor Documentation

AudioDecoder::AudioDecoder	(	quint32	aSampleRate = 8000,
		quint32	aNumChannels = 1
	)

Constructor.

Member Function Documentation

frameDecoded

void AudioDecoder::frameDecoded ( quint32  aCallId, quint32  aSeqNo, const QByteArray &  aEncodedData, Hash  aOriginatingNode  )

signal

This signal is emitted when decoded frame is ready for further processing, typically by audio mixer.

Parameters

aCallId	call where frame originates from
aSeqNo	sequence number of the frame in the call
aEncodedData	raw de-coded audio data. In practice the byte-array holds array of floats, each preseting one sample, in range [-1,1].

frameReceived

void AudioDecoder::frameReceived ( quint32  aCallId, quint32  aSeqNo, const QByteArray &  aAudioData, Hash  aOriginatingNode  )

slot

Received audio frames to be de-coded are connected to this slot.
