Abstract: A method for processing a time-domain signal with transient oscillations includes: performing, by one or more computer systems, a time-frequency representation transform on the time-domain signal to obtain a plurality of coefficients for, with a coefficient corresponding to a presence of an impulse response of a filter used by the time-frequency representation transform; selecting one or more of the coefficients, with the selected one or more of the coefficients having attributes that are more indicative of the transient oscillations; and reconstructing, based on performing an inverse transform on the selected one or more coefficients, a portion of the time-domain signal that represents the transient oscillations.
