The expression can also use pi, sin, cos, and Python operators. The expression has access to the variables x, y, t, and r, which are all on the range [0, 1). In the spirit of bytebeat, this wraps up the boilerplate so that you can generate two-second grayscale gifs with a single expression, which is evaluated at every point to create each frame. random () x, y, t = col / width, row / height, i / frames frame = exp_as_func () process. zeros (( width, height )) for row in range ( width ): for col in range ( height ): r = np. cos, 0 frames = 32 for i in range ( frames ): frame = np. argv ) # Put some convenient things in the namespace: run_async ( pipe_stdin = True, pipe_stderr = True ) ) # Interestingly, this hack runs much faster than using compile + eval.Įxp_as_func = eval ( 'lambda: ' + sys. format ( width, height ), framerate = fps ). So, here are some brief examples, comprising the possibilities '.

This post is more preliminary: all about getting audio and video samples into Python (say, from files or hardware) and/or out of it and into the world. Some might not think of it as a language for DSP, but its excellent ecosystem (including the SciPy squad) and expressiveness make it a very useful tool.įuture posts may discuss some of the many interesting things to do with audio and video. Python, while not perfect, is pretty reasonable among dynamic languages, exceedingly convenient, and finally past the era of 2-vs-3. To that end: here are the quickest ways I know to get audio and video into or out of Python. It’s nice, and sometimes essential, to have the flexibility of a general programming language, which enables you to express what you want precisely using the abstractions of your choosing.

I often find that these do not perfectly serve my purposes: I know what I want, but existing tools might not support it well or at all. Tools for working with audio and video abound.
