  • AES E-Library » Detection and Extraction of Transients for ...

    An algorithm for the detection and extraction of transient signal components is presented. It is based on the detection of sharp onsets of the signal power in time direction of the complex time frequency domain. Afterwards the detected transients are extracted in the corresponding MDCT spectrum. The audio signal containing only the extracted transients is synthesized using the inverse MDCT.
