It works somewhat strange, and you can't control its behavior at all.
With sox, there are a lot of parameters to tune. There are different
source materials, a lot types of speakers with different acoustic
properties, and if you want to do convertion without loosing too much of
original sound and without distorion, you gotta need sox capabilities.
