NumPy is the fundamental package for scientific computing in Python.
It is a library for the Python programming language, adding support for large,
multi-dimensional arrays and matrices, along with a large collection of high-level
mathematical functions to operate on these arrays.
The SciPy library is one of the core packages that make up the SciPy stack.
It provides many user-friendly and efficient numerical routines such as routines for numerical
integration and optimization.
Software library written for data manipulation and analysis in Python.
Offers data structures and operations for manipulating numerical tables and time series.
Matplotlib is a Python 2D/3D plotting library which produces publication quality figures
in a variety of hardcopy formats and interactive environments across platforms.
The higher level probability algorithms for machine learning.
If you know the rules for dealing with your data then you will want something lower level.
If you want the computer to learn the rules for you and give you probabilistic answers then this library is useful.
This requires study of metaparameters to understand if you are getting a more correct answer than not.
Don't reinvent the wheel !
High level API for the manipulation of an audio file.
FFmpeg is the leading multimedia framework, able to decode, encode, transcode, mux,
demux, stream, filter and play pretty much anything that humans and machines have created. e.g.) this is used
to encode and decode mp3 files.
