Detailed Description

Central monitoring panel of the Mema.Mo application.

MemaMoComponent is the active-state UI of the Mema.Mo tool — the monitoring companion in the Mema tool suite. When a TCP connection to a Mema server has been established, this component owns a pair of ProcessorDataAnalyzer instances (one for input audio, one for output audio) that process the streamed AudioOutputBufferMessage / AudioInputBufferMessage payloads received over the network and broadcast level/spectrum data to the pluggable visualisation components.

Visualisation modes (mutually exclusive, switched from MainComponent settings):

  • Meterbridge — horizontal or vertical peak/RMS/hold level bars for every channel.
  • 2-D spatial field — positional level indicators for speaker layouts from LRS up to 9.1.6 ATMOS, rendered by TwoDFieldOutputComponent.
  • Waveform — scrolling audio waveform plots per channel.
  • Spectrum — frequency-domain FFT magnitude display per channel.

The component communicates back to MainComponent via the onExitClick callback when the user requests a disconnection.

MainComponent — owns this component and drives the Discovering/Connecting/Monitoring state machine.
Mema::ProcessorDataAnalyzer — performs peak/RMS/hold metering and FFT analysis on received buffers.
