Streaming Audio Processing

Design and run real-time audio processing in MATLAB and Simulink using Audio Toolbox streaming objects. These objects maintain internal state across frames, support tunable properties, and provide built-in visualization.

When to Use

• Building frame-based audio processing loops
• Filtering audio in real time (crossover, EQ, shelving, octave)
• Applying dynamic range control (compressor, limiter, expander, noise gate)
• Measuring audio levels (peak, loudness, SPL, octave-band spectra)
• Resampling audio signals (sample rate conversion)
• Applying long impulse responses in real time (frequency-domain filtering)
• Tuning audio parameters interactively while streaming
• Visualizing filter responses or compressor characteristics
• Controlling audio parameters with MIDI devices
• Building audio processing chains in Simulink
