AB  - A transform codec employing efficient algorithm for detection of spectral tonal components is presented. The tonality measure used in MPEG psychoacoustic model is replaced with the method providing adequate tonality estimates even if the tonal components are deeply frequency modulated. The reliability of hearing threshold estimated using psychoacoustic model with standardized tonality measure and the proposed one is investigated using objective quality testing methods. The proposed tonality estimator is also used as a basis for detector of noise-like signal bands. Instead of quantizing the noise-like signal components according to the usual transform coding scheme, the signal bands containing only noise-like components are filled with locally generated noise in the decoder. The results of the listening tests reveling usefulness of employed tonality estimation method for such a coding scenario are presented
