A novel precise method of signal analysis in the time-frequency domain is presented. A signal energy distribution is estimated by discard and displacement of energy parts of the classical spectrogram. A channelized instantaneous frequency and a local group delay are used in order to energy replacement. Additionally, newly introduced representations such as: a channelized instantaneous bandwidth and a local group duration are used for remove some part of irrelevant energy. An obtained energy distribution called attractogram is highly concentrated. And it causes that mono-components of an analyzed signal are precisely localized in the time-frequency domain. The presented method is utilised in order to acustical signals analysis
