Signal processing is an import area. It deeply embeds in digital life.

How can I ignore it so many years?

How signal processing affects daily life

Machine learning is essentially signal processing.

Video/Audio recording is just engineering. The vital part is also signal processing; such as face detection, object identification, data overlay & analysis…

Looking from SP perspective

my computer usage is pretty bad: To do good signal processing, I need good hardware: Strengthen my body; Use good PC; Good protection;

I need to measure the environment and infer harms; then take action and don’t let bad environment hurt me;

To increase SP capacity I need to increase information and money flow gradually…

Programming Language

Audio play is mainly C (SDL2); video is mainly C/C++ (ffmpeg, openGL);

However C is hard to manage with pointer and memory; luckily I just learned Go.

Python can do some quick and dirty things, but speed and deep knowledge is a downside. It also makes me form a habit to search existing solutions online…
