Advanced method of signal time-stretching based on tonal and non-tonal segment detection
 Vomáčka, Jan ; Trzos, Michal (referee) ; Balík, Miroslav (advisor)
This thesis deals with the method for time conversion of an audio signal based on a different approach to groups tonal and non-tonal segment signal implemented in Matlab. The first part deal with methods for musical signal processing based on time compression or expansion and describes the problems associated with the current way of implementing these methods. The following describes the methods of variable segmentation and tonal and non-tonal components detection in the audio recording. At the second part are these methods of variable segmentation, tonal component detection and time compression or expansion implemented in MATLAB. At the third part is performed testing on sound recordings and evaluation of results.
