  • Guitar String Sound Retrieved from Moving Pixels

    The aim of this study was to develop a method of visual recording and analyzing the vibrations of guitar strings using high-speed cameras and dedicated video processing algorithms. The recording of a plucked string reveals the way in which the deformations propagate, composing the standing and travelling wave. The paper compares the results for a few selected models of classical and acoustic guitars, and it involves processing...

  • Modelling and Measurement of Folk Guitar: Truss Rod and Strings in Numerical Analysis of Tone

    The study makes an attempt to model a complete vibrating guitar including its non-linear features, specifically the tension-compression of truss rod and tension of strings. The purpose of such a model is to examine the influence of design parameters on tone. Most experimental studies are flawed by uncertainties introduced by materials and assembly of an instrument. Since numerical modelling of instruments allows for deterministic...

  • Comparison of two methods of sound extraction from guitar string video recordings

    Publication

    A comparison of two sound extraction methods from guitar string video recordings is presented in the paper. A brief overview of highframe rate camera technology and possible applications are included. The method using the image analysis from two such cameras is presented. The cameras are placed at the angle of 90 degrees for recording the image in three planes. The results achieved...

    Michał Lech was born in Gdynia in 1983. In 2007 he graduated from the faculty of Electronics, Telecommunications and Informatics of Gdansk University of Technology. In June 2013, he received his Ph.D. degree. The subject of the dissertation was: “A Method and Algorithms for Controlling the Sound Mixing Processes by Hand Gestures Recognized Using Computer Vision”. The main focus of the thesis was the bias of audio perception caused...

  • Jarosław Chojnacki prof. dr hab. inż.

    Born in 1961 in Bydgoszcz, professional education started at the Chemical Technical Highschool  (I. Łukasiewicz). He graduated from the Faculty of Chemistry at the Gdańsk University of Technology in 1986, defending the work on ion-selective electrodes. Subsequent studies were related to organic and siliconorganic synthesis and, from 2002 year on, to crystallography. The doctoral thesis concerned the Silanotiolanes of coinage metals...

  • Application of Fast Cameras to String Vibrations Recording

    Publication

    A hardware and software solution for guitar string vibration measurement by fast cameras is described. Orthogonal setup for 3D image acquisition is proposed capable to capture several thousand image frames per second. Dedicated image processing algorithm was developed and described in the paper, aimed at tracking the movement of some selected points along the string. Fast and accurate tracking results provided a detailed information...

  • Using concentrated spectrogram for analysis of audio acoustic signal

    Publication

    The paper presents results of time-frequency analysis of audio acoustic signals using the method of Concentrated Spectrograph also known as ''Cross-spectral method'' or ''Reassignment method''. Presented algorithm involves signal's local group delay and channelized instantaneous frequency to relevantly redistribute all Short-time Fourier transform lines in time-frequency plain. The main intention of the paper is to compare various...

  • Pose-Configurable Generic Tracking of Elongated Objects

    Publication

    - Year 2013

    Elongated objects have various shapes and can shift, rotate, change scale, and be rigid or deform by flexing, articulating, and vibrating, with examples as varied as a glass bottle, a robotic arm, a surgical suture, a finger pair, a tram, and a guitar string. This generally makes tracking of poses of elongated objects very challenging. We describe a unified, configurable framework for tracking the pose of elongated objects, which...
