RAPID Audio Prototyping Device

Real-time Audio System Check (R-TASC)

An audio system problem identification and debugging process supported in Audio Weaver designed to verify hardware performance, software performance, and functionality

Provides visibility and access to:
  • All aspects of the system
  • All signals in real-time
    Identifies issues related to:
    • Software integration
    • Microphone and loudspeaker assembly
    Tests advanced processing chains
    Tests advanced processing chains to:
    • Get visibility into multi-channel feedback paths for AEC
    • Inspect signal integrity before ASRs and ML blocks
    Eliminates the need to:
    • Use specialized interfaces and audio workstations
    • Interfere with the operation of the audio system

    Real-time Troubleshooting
