摘要：
A method is specified for recognition of the start of a note in the case of percussion or plucked musical instruments, in the case of which an envelope curve following function is formed from an audio signal, a comparison variable is formed from a current value of the envelope curve following function and a predecessor value corresponding to an earlier value, and the start of a note is defined at a point in time at which the comparison value exceeds a threshold value.
