[Android Q&A, Help & Troubleshooting] mechtifs:
These day I want to have 5 kinds of sound effects on my device. My English is poor, so maybe there will be some grammar mistakes. Could you help me to find problems in the audio_effects.conf?

# 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>
# [ int|short|float|bool|string <value> ]
# ...
# }
# }
# <param 2 name > {<param> <value>}

When I use it, only v4a still working, the other will FC. First, I make sure that other things are right. Please tell me how to fix it, thx very much!
