In this paper, we present an incremental improvement of a known fundamental frequency estimation algorithm for monophonic signals. This is viewed as a case study of using our signal graph based synthesis language, PWGLSynth, for audio analysis. The roles of audio and control signals are discussed in both analysis and synthesis contexts. The suitability of the PWGLSynth system for this field of applications is examined and some problems and future work is identified.
