  - Year 2014

  The aim of this paper is to present a novel approach to the Virtual Bass Synthesis (VBS) algorithms applied to portable computers. The developed algorithms are related to intelligent, rule-based setting of synthesis parameters according to music genre of an audio excerpt and to the type of a portable device in use. To find optimum synthesis parameters of the VBS algorithms, subjective listening tests based on a parametric procedure...

  - Przegląd Telekomunikacyjny + Wiadomości Telekomunikacyjne - Year 2014

  W pracy przedstawiono algorytm inteligentnej adaptacji parametrów syntezy niskich częstotliwości w urządzeniach przenośnych w zależności od odtwarzanego gatunku muzycznego (Smart VBS). Proponowany algorytm wykorzystuje metody generacji harmonicznych oparte na generatorze funkcji nieliniowych (NLD) i wokoderze fazowym (PV). Dla znalezienia optymalnych parametrów syntezy przeprowadzono testy subiektywne sprawdzające powiązanie parametrów...

• Smart Virtual Bass Synthesis Algorithm Based on Music Genre Classification

  Publication

  • T. Sanner
  • B. Kostek

  - Year 2014

  The aim of this paper is to present a novel approach to the Virtual Bass Synthesis (VBS) algorithms applied to portable computers. The proposed algorithm employed automatic music genre recognition to determine the optimum parameters for the synthesis of additional frequencies. The synthesis was carried out using the non-linear device (NLD) and phase vocoder (PV) methods depending on the music excerpt genre. Classification of musical...

  - Year 2013

  An experiment conducted to validate possibility of use virtual bass synthesis (VBS) algorithm in a portable computer is presented. The subjective listening tests based on the procedure of pairwise comparison between VBS, based on the so-called missing fundamental phenomenon, and standard bass boost technique are employed. The evaluation was carried out in two types of conditions: in a professional listening room and employing an...

  - Year 2013

  For the purpose of video surveillance software quality assessment in this work the ISO/IEC-9126 norm was used with a particular focus on maintainability of the software system. The paper presents a study on the connection between software metrics derived from the static analysis of the source code and changeability of the video surveillance software system. It is shown that meeting requirements of software quality metrics may result...

  - Year 2013

  An experiment conducted to validate a possibility of use a single active electrode EEG device for detecting Steady State Visually Evoked Potentials (SSVEP) is shown. A LED stimulator was applied to stimulate patients with two different frequencies - 13 Hz and 17 Hz. First, EEG signals were recorded and pre-processed using MATLAB software. In the next step recordings were analysed and classified employing the WEKA software. As indicated...
