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…
