Abstract

Dinamička regulacija razine često je korišten i praktičan alat za upravljanje dinamičkim
rasponom audio signala. Dinamički procesori imaju dugu povijest korištenja u elektroakusti
čnom lancu i mogu se implementirati u analognoj i digitalnoj domeni. U
ovom radu, teorijski su obradeni principi dinamičke obrade audio signala. Nadalje,
korištenjem Python i C++ programskih jezika povezanih preko Cython sučelja,
programski je izvedena feedforward topologija dinamičkog procesora s grafičkim korisni
čkim sučeljem koji omogućuje namještanje prijenosne karakteristike i osnovnih
parametara dinamičke kompresije/ekspanzije razine audio signala.

Abstract (english)

Dynamic range control is a common and practical tool used to control the dynamic
range of an audio signal. Dynamic processors have a long history of use in the electroacoustic
chain and they can be implemented both in analog and digital domain. In
this paper, basics principles of dynamic audio signal processing are discussed. Furthermore,
feedforward dynamic processor with a graphical user interface is developed
in Python and C++ programming languages where Cython is used as an interface
between the two. Software implementation allows for the transfer function parameters
tuning.
