Pymousetrap provides access to a C-implemented shared library that efficiently stores information about a 2-dimensional grid (a mousetrap). The mousetrap is integer resolution, and supports works very similarly to graphics libraries; mousetraps can be 'blitted' onto each other, with transparency. This code was written with the intent to simplify the way mouse click events were handled, but probably has other uses.
audio_conv.py converts between several different audio formats. Conversion works by converting the input file(s) to an intermediate wav file, optionally normalizing the wav, then writing out the output file with appropriate tag information. This script handles wildcards, works recursively, and handles filenames with spaces and other special characters (question marks, quotation marks, etc).
