# 20.2 `AL` -- Constants used with the `al` module

Availability: IRIX.

This module defines symbolic constants needed to use the built-in module `al` (see above); they are equivalent to those defined in the C header file `<audio.h>` except that the name prefix "`AL_`" is omitted. Read the module source for a complete list of the defined names. Suggested use:

      import al
      from AL import *
