-- A program and a library to modify the amplitudes of the sound representations 
-- created by mmsyn7ukr or mmsyn7ukr-array package or somehow otherwise. Besides
-- it can be used to adjust volume for the sequential \"result*.wav\" files.

module Main where

import Control.Exception (onException)

-- | The main and the only one function in the module. If you specify a one command line argument, which can be obtained by running @mmsyn7s@ program
-- with the needed to be sounded (with sound representations) Ukrainian text (please, refer to: https://hackage.haskell.org/package/mmsyn7s).
