Description
  • Hodnoceni audio kompresnich artefaktu. (cs)
  • The present paper deals with the subjective evaluation of audio-coding systems. From this evaluation, it is found that depending on the type of the signal and the algorithm of the audio-coding system used, different types of audible errors arise. These errors are called coding artefacts. Nevertheless while in the auditory domain there can be perceivable three kinds of artefacts, the author purposes that in the coding domain there is only one common cause for the artefact aparition, the non-efficient tracking of transient-stochastic signals. For this purpose, state-of-the art of audio coding systems use a wide range of signal processing techniques, from which the application of the wavelet transform is described here.
