Signal Types
------------

MuzGen use different kind of signals for sound design.


Constant
^^^^^^^^

The simplest signal is the **constant signal**. It
returns the same frame everytime. It is used mostly as argument of
commands. In MuzScript, every numbers are constant signals.

.. code-block::

   # constant signal
   142


Sine
^^^^

The sine wave signal is the fundamental signal in sound theory.
It takes two arguments: a frequency and an amplitude.
Mathematically we can define our sine using the following formula:

.. math::

   amplitude * sin(2 * pi * frequency / samplerate * time)


To generate a sine, we can use the ``sine`` command.

.. code-block::

   # sine signal with a frequency of 440 and an amplitude of 1
   [sine 440 1]
