Processador de áudio e otimizador de fones de ouvido independente

Abstract

The project aims at developing and assembling a device capable of altering and enhancing audio signals from laptops and cellphones when connected to headfones, according to the user’s preferences. Through digital signal processing and high quality conversion/amplification, the resulting product can reduce bottlenecks in the audio delivery process from its digital delivery by the transmitting device to the final analog stage. Its main functionality lies in improving the sound quality delivered to entry-level and mid-range headphones without the need for expensive equipment. It also focuses on being a portable and self-contained (i.e. without the need for specific drivers or software on the platform to which it is connecting) allowing for greater flexibility in its use. Through filter composition, the device allows for more complex ilters, such as equalization, in order to allow the customization of the original signal.
