• audiolazy/lazy_lpc.py
• audiolazy/lazy_misc.py
• audiolazy/lazy_poly.py
• docs/conf.py
• math/lowpass_highpass_bilinear.py

Fixes:

• Should read synchronize rather than synchonize.
• Should read symmetric rather than simmetric.
• Should read miscellaneous rather than miscellanous.
• Should read cloning rather than clonning.
• Should read capabilities rather than capabilites.
• Should read approximation rather than aproximation.
• Should read access rather than acess.
