  • Attack transient detection for a musical instrument signal
    Patent number: 6091013
    Abstract: An attack transient detector determines the moment of note onset; e.g. the time at which a guitar string is plucked; from a signal generated by a musical instrument. Detection of the attack transient causes the generation of a trigger signal which can be used to control processing of the musical instrument signal.
