Automatic Transcription of Polyphonic Musical Signals with Linear Matching Pursuit By Andrew McLeod The Harmonic Matching Pursuit (HMP) algorithm has offered promising results in the automatic transcription of audio signals. It works by decomposing the given signal into a set of harmonic atoms, and then grouping those atoms into individual notes. HMP has shown very promising results, but more r...

In this paper, we introduce a new adaptive data analysis method to study trend and instantaneous frequency of nonlinear and nonstationary data. This method is inspired by the Empirical Mode Decomposition method (EMD) and the recently developed compressed (compressive) sensing theory. The main idea is to look for the sparsest representation of multiscale data within the largest possible dictiona...
