AudioLazy is a package written in pure Python proposing digital audio signal
processing (DSP).

It prioritizes code expressiveness, clarity and simplicity, without precluding
the lazy evaluation, and can be used together with Numpy, Scipy and
Matplotlib as well as default Python structures like lists and generators.

It also features:

- A ``Stream`` class for finite and endless signals representation with
  elementwise operators (auto-broadcast with non-iterables) in a common
  Python iterable container accepting heterogeneous data;
- Strongly sample-based representation (Stream class) with easy conversion
  to block representation using the ``Stream.blocks(size, hop)`` method;
- Sample-based interactive processing with ``ControlStream``;
- ``Streamix`` mixer for iterables given their starting time deltas;
- Multi-thread audio I/O integration with PyAudio;
- Linear filtering with Z-transform filters directly as equations (e.g.
  ``filt = 1 / (1 - .3 * z ** -1)``), including linear time variant filters
  (i.e., the ``a`` in ``a * z ** k`` can be a Stream instance), cascade
  filters (behaves as a list of filters), resonators, etc.. Each
  ``LinearFilter`` instance is compiled just in time when called;
- Zeros and poles plots and frequency response plotting integration with
- Linear Predictive Coding (LPC) directly to ``ZFilter`` instances, from
  which you can find PARCOR coeffs and LSFs;
- Both sample-based (e.g., zero-cross rate, envelope, moving average,
  clipping, unwrapping) and block-based (e.g., window functions, DFT,
  autocorrelation, lag matrix) analysis and processing tools;
- A simple synthesizer (Table lookup, Karplus-Strong) with processing tools
  (Linear ADSR envelope, fade in/out, fixed duration line stream) and basic
  wave data generation (sinusoid, white noise, impulse);
- Biological auditory periphery modeling (ERB and gammatone filter models);
- Multiple implementation organization as ``StrategyDict`` instances:
  callable dictionaries that allows the same name to have several different
  implementations (e.g. ``erb``, ``gammatone``, ``lowpass``, ``resonator``,
  ``lpc``, ``window``);
- Converters among MIDI pitch numbers, strings like "F#4" and frequencies;
- Polynomials, Stream-based functions from itertools, math, cmath, and more!
