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