    102 # Audio preprocessor configurations.
    103 # The pre processor configuration consists in a list of elements each describing
    104 # pre processor settings for a given input source. Valid input source names are:
    105 # "mic", "camcorder", "voice_recognition", "voice_communication"
    106 # Each input source element contains a list of effects elements. The name of the effect
    107 # element must be the name of one of the effects in the "effects" list of the file.
    108 # Each effect element may optionally contain a list of parameters and their
    109 # default value to apply when the pre processor effect is created.
    110 # A parameter is defined by a "param" element and a "value" element. Each of these elements
    111 # consists in one or more elements specifying a type followed by a value.
    112 # The types defined are: "int", "short", "float", "bool" and "string"
    113 # When both "param" and "value" are a single int, a simple form is allowed where just
    114 # the param and value pair is present in the parameter description
