Detailed Description

Add a controlled amount of noise to the incoming signal.

[add_noise]
`type <uniform/gaussian>(gaussian)`
Type of noise to add.
`range <range>(1.0)`
Amount of noise to add.
`seed <seed>(-1)`
Initialization of the random generator. By default (no 'seed' specified), a random value will be used as seed, making the preprocessing variable, i.e. processing the same file twice will give different results. When a seed is specified, the seed is combined with a hash of the file name to select a different noise pattern for each file.
`order <dependent/independent>(dependent)`
Select whether the added noise depends on the order of the files in the corpus or not; this allows the addition of different noise to the same file by processing that file twice (or more).
