    • openAccess   Efficient target-response interpolation for a graphic equalizer 

      BELLOCH, JOSE A.; Välimäki, Vesa IEEE (2016-05)
      A graphic equalizer is an adjustable filter in which the command gain of each frequency band is practically independent of the gains of other bands. Designing a graphic equalizer with a high precision requires evaluating ...

    • openAccess   Efficient Velvet-Noise Convolution in Multicore Processors 

      BELLOCH, JOSE A.; Badia, Jose M.; León Navarro, Germán; Välimäki, Vesa Audio Engineering Society (2024-06-02)
      Velvet noise, a sparse pseudo-random signal, finds valuable applications in audio engineering, such as artificial reverberation, decorrelation filtering, and sound synthesis. These applications rely on convolution operations ...

    • openAccess   GPU-based Dynamic Wave Field Synthesis using Fractional Delay Filters and Room Compensation 

      BELLOCH, JOSE A.; González, Alberto; Quintana-Orti, Enrique S.; Ferrer, Miguel; Välimäki, Vesa IEEE (2017-02)
      Wave Field Synthesis (WFS) is a multichannel audio reproduction method, of a considerable computational cost that renders an accurate spatial sound field using a large number of loudspeakers to emulate virtual sound ...

    • openAccess   Multicore implementation of a multichannel parallel graphic equalizer 

      BELLOCH, JOSE A.; Badía, José; León, Germán; Bank, Balázs; Välimäki, Vesa Springer (2022-04-22)
      Numerous signal processing applications are emerging on mobile computing systems. These applications are subject to responsiveness constraints for user interactivity and, at the same time, must be optimized for energy ...
