Audio Processing System

An Audio Processing System is a signal processing system that can perform audio manipulation tasks through digital signal processing techniques.

• AKA: Sound Processing System, Audio System, Acoustic Processing System, Audio DSP System.
• Context:
  • It can typically perform Signal Analysis through frequency transforms.
  • It can typically implement Noise Reduction through filtering algorithms.
  • It can typically support Audio Enhancement through equalization techniques.
  • It can typically handle Format Conversion between audio codecs.
  • It can typically manage Sample Rate through resampling methods.
  • It can often enable Echo Cancellation for communication systems.
  • It can often provide Audio Effects through signal modification.
  • It can often support Multi-Channel Processing for spatial audio.
  • It can range from being a Real-Time System to being an Offline System, depending on its processing constraints.
  • It can range from being a Single-Channel System to being a Multi-Channel System, depending on its channel support.
  • It can range from being a Linear System to being a Non-Linear System, depending on its processing method.
  • It can range from being a Low-Level System to being a High-Level System, depending on its abstraction level.
  • ...
• Example(s):
  • Speech Processing Systems, such as:
    • Speech Enhancement System for voice clarity.
    • Speaker Separation System for cocktail party problem.
    • Voice Activity Detection System for speech segmentation.
  • Music Processing Systems, such as:
    • Audio Mixing System for music production.
    • Music Information Retrieval System for audio analysis.
    • Audio Mastering System for final production.
  • Communication Systems, such as:
    • Acoustic Echo Canceller for teleconference.
    • Noise Suppression System for call quality.
    • Audio Codec System for compression.
  • ...
• Counter-Example(s):
  • Video Processing System, which handles visual data.
  • Text Processing System, which handles written content.
  • Image Processing System, which handles static visuals.
