Introduction

Simpl is an open source library for sinusoidal modelling written in C/C++ and Python, and making use of Scientific Python (SciPy). The aim of this project is to tie together many of the existing sinusoidal modelling implementations into a single unified system with a consistent API, as well as providing implementations of some recently published sinusoidal modelling algorithms, many of which have yet to be released in software. Simpl is primarily intended as a tool for other researchers in the field, allowing them to easily combine, compare and contrast many of the published analysis/synthesis algorithms.
