-# random dsp code
-
-it's a bunch of half-baked python code that's kinda handy.
-
-don't expect commits, docs, or comments to be any verbose.
-
-## the stuff
-
-* a basic BS.1770-3 normalization implementation
-— [bs.py](/lib/bs.py)
-
-* biquad butterworth/chebyshev filters [(via DSPFilters)][dspf]
-— [nsf.py](/lib/nsf.py)
-
-* bilinear transformation: s-plane to z-plane
-— [planes.py](/lib/planes.py)
-
-* various functions for biquad filters
-— [bq.py](/lib/bq.py) [\_\_init\_\_.py](/lib/__init__.py)
-
-* some functions for state-variable filters [(via Raph Levien)][svf]
-— [svf.py](/lib/svf.py)
-
-* sine sweeps, and the Optimized Aoshima's Time-Stretched Pulse [(via here)][sweeps]
-— [sweeps.py](/lib/sweeps.py)
-
-* a lot of stuff for magnitude plotting like tilting and smoothing
-— [fft.py](/lib/fft.py) [smoothfft.py](/lib/smoothfft.py) [\_\_init\_\_.py](/lib/__init__.py)
-
-* rough experiments with psychoacoustic equalization ("neon pink" and other crap)
-— [data.py](/lib/data.py) [\_\_init\_\_.py](/lib/__init__.py)
-
-* miscellaneous matplotlib stuff
-— [plot.py](/lib/plot.py)
-
-* miscellaneous utility functions
-— [util.py](/lib/util.py) [wav.py](/lib/wav.py)

-
-all wrapped up in a inconveniently named "lib" module!
-
-## dependencies
-
-python 3.5+
-
-numpy scipy sympy matplotlib ewave
-
-usually run in an ipython environment.
