+# 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
+# pre_processing {
+# <input source name> {
+# <fx name> {
+# <param 1 name> {
+# param {
+# int|short|float|bool|string <value>
+# [ int|short|float|bool|string <value> ]
+# ...
+# }
+# value {
+# int|short|float|bool|string <value>
