    Build your own private, encrypted, open-source Dropbox-esque sync folder

Prerequisites:

One or more clients running a UNIX-like OS. Examples are given for Ubuntu 12.04 LTS, although all software components are available for other platforms as well (e.g. OS X). YMMV
A cheap Ubuntu 12.04 VPS with storage. I recommend Backupsy, they offer 250GB storage for $5/month. Ask Google for coupon codes.

Software components used:

Unison for file synchronization
EncFS for folder encryption


## bl_waveforms.py

"""
Bandlimited versions of scipy.signal.waveforms.

Intent is mathematical perfection over performance;
these use additive synthesis, so they are slow, but exact.

Less ideal methods using BLIT:
Sawtooth can be made by integrating BLIT minus a DC value to prevent integrator wandering off
Square can be made by integrating bipolar BLIT
