|Abstract:||This article comments on a frequency estimator which was proposed by  and shows empirically that it exhibits a much larger mean squared error than a well known frequency estimator by . It is demonstrated that by using a heuristical adjustment  the performance can be greatly improved. Furthermore, references to two modern techniques are given, which both nearly attain the Cramér-Rao bound for this estimation problem.  U. Ligges. Transkription monophoner Gesangszeitreihen.
