Computer Music and Audio Processing Modern music often relies on computer systems for recording, shaping sound, and performing in real time. This article covers basic ideas in computer music and audio processing, with simple ideas you can try at home. At its core, computer music is about turning ideas into sound using digital tools. You work with signals, streams of numbers that represent air pressure over time. With the right steps, you can craft tones, textures, and percussion from raw data. ...

Image and Audio Processing: Techniques and Tools Images and audio are both data that computers can analyze and improve. The ideas are similar: clean up the signal, reveal useful patterns, and present results that people can act on. Start with a clear goal, then choose a representation that makes the task easier. Images often need cleaning, enhancement, or extraction of features. Common steps include reducing noise, adjusting brightness or color, sharpening edges, and detecting shapes. Audio work focuses on clarity, loudness, and meaningful content, such as removing hiss, equalizing balance, and analyzing frequency content. ...

Computer Vision and Speech Processing Fundamentals Computer vision and speech processing help machines understand our world. Vision systems look at pictures or videos to identify objects, scenes, and actions. Speech processing turns spoken language into text or meaning. Both fields use data, careful preprocessing, and learning from examples. They share ideas like features, models, and evaluation, but each has its own challenges, such as lighting changes for vision or noise in audio. ...
