+Source manipulation
+===================
+
+We have created a source in the last section.
+As said previously, its properties can be manipulated
+to create wanted effects.
+
+Moving the source
+-----------------
+
+Changing :py:meth:`Source.position` is one of the most noticeable,
+but first, we have to enable spatialization via :py:attr:`Source.spatialize`.
+
+.. code-block:: python
+
+   from time import sleep
+   from palace import Device, Context, Source, decode
+
+   filename = 'some_audio.ogg'
+   with Device() as dev, Context(dev) as ctx:
+       with Source() as src:
+           src.spatialize = True
+
+           dec = decode(filename)
+           dec.play(12000, 4, src)
+           while src.playing:
+               sleep(0.025)
+               ctx.update()
+
+Now, we can set the position of the source in this virtual 3D space.
+The position is a 3-tuple indicating the coordinate of the source.
+For those who didn't know this yet: x is for left-right, y is for up-down,
+and z is for back-forth.
+For example, this will set the source above you:
+
+.. code-block:: python
+
+   src.position = 0, 1, 0
+
+*Note*: for this too work, you have to have HRTF enabled.  You can check that
+via :py:attr:`Device.current_hrtf`.
+
+You can as well use a function to move the source automatically by writing
+a function that generate positions.  A simple example is circular motion.
+
+.. code-block:: python
+
+   from itertools import takewhile, count
+   def rotate(t):
+       return sin(t), 0, -cos(t)
+   ...
+   for i in takewhile(src.playing, count(step=0.025)):
+       src.position = rotate(i)
+       ...
+
+A more well-written example of this can be found on our `repository`_.
+
+Pitch
+-----
+
+Modifying :py:attr:`pitch` changes the playing speed, effectively changing
+pitch.  Pitch can be any positive number.
+
+.. code-block:: python
+
+   src.pitch = 7  # quite high pitch
+   src.pitch = 0.4  # low pitch
+
+Air absorption factor
+---------------------
+
+:py:attr:`Source.air_absorption_factor` simulates atmospheric high-frequency
+air absorption. Higher values simulate foggy air and lower values simulate
+drier air.
+
+.. code-block:: python
+
+   src.air_absorption_factor = 9  # very high humidity
+   src.air_absorption_factor = 0  # by default: dry air
