Multipurpose Digital Audio Effect: Combining Different Techniques Within a Single Device

This paper introduces an audio effect (FX) plugin module capable of processing the input signal with several common types of audio manipulation within up to 30 individual bands. The advantage of the proposed implementation lies mostly in its versatility, with potential applications ranging from simple delay up to spatial simulations, such as reverb. Unlike the existing commercial solutions that typically split the input signal into a fixed set of frequency bands, the proposed FX processes the input signal in parallel across all bands, with each band applying optional filtering and other processing independently. The proposed FX was implemented using the C++ programming language and the JUCE framework.
