Static Public Member Functions inherited from Mema::SerializableMessage
static SerializableMessage *	initFromMemoryBlock (const juce::MemoryBlock &blob)

Protected Attributes inherited from Mema::SerializableMessage
SerializableMessageType	m_type = SerializableMessageType::None
	Type discriminator stored in the first 4 bytes of every serialised frame.

int	m_userId = -1
	Optional connection-id tag for echo-suppression (-1 = not set).

Detailed Description

Carries a pre-matrix input audio buffer streamed continuously from Mema to subscribed clients.

Instantiated by MemaProcessor in audioDeviceIOCallbackWithContext() after the input data has been captured but before it passes through the crosspoint matrix. Clients that have subscribed to AudioInputBuffer traffic (via DataTrafficTypeSelectionMessage) receive one of these per audio device block.
