A signal processing method for the separation of concurrent harmonic sounds is described. The method is based on a two-stage approach. First, a multipitch estimator is applied to find initial sound parameters which are reliable, but inaccurate and static. In a second stage, more accurate and time-varying sinusoidal parameters are estimated in an iterative procedure, which imposes certain constr...

We propose a new method for the musical pitch and instrument estimation of polyphony for transcription. Most of previous methods are based on the extraction of the pitch frequencies. But the extraction of the pitches is di cult since the musical sound has many harmonic components and these components are changed complicatedly depending on the tones and musical instruments. The principle of our ...

Family therapy is moving increasingly toward evidence-based practice and competency-based training. This article explores what might seem to be an unlikely link between social constructionist supervision, which is based on dialogic and fluid processes of meaning-making, and the increasing reliance on discrete core competencies in the education and training of family therapists. We propose an al...

The Clavinet is an electromechanical musical instrument produced in the mid-twentieth century. As is the case for other vintage instruments, it is subject to aging and requires great effort to be maintained or restored. This paper reports analyses conducted on a Hohner Clavinet D6 and proposes a computational model to faithfully reproduce the Clavinet sound in real time, from tone generation to...

We present a new probabilistic model for transcribing piano music from audio to a symbolic form. Our model reflects the process by which discrete musical events give rise to acoustic signals that are then superimposed to produce the observed data. As a result, the inference procedure for our model naturally resolves the source separation problem introduced by the the piano’s polyphony. In order...
