How does real-time audio processing impact the quality of live music performances?

What are the key differences between real-time audio processing and offline audio processing?

The key differences between real-time audio processing and offline audio processing lie in the timing and immediacy of the processing. Real-time audio processing occurs instantaneously as the audio is being captured or played, allowing for immediate adjustments and effects. In contrast, offline audio processing involves processing the audio after it has been recorded, which can be more time-consuming but may offer more advanced editing capabilities and precision.
