A python package to analyse guitar sounds. Developed as a lutherie research analysis tool with the Bruand Lutherie School. The main goal of this project is to provide a tool to efficiently analyse sound data from research projects in musical instrument design. While sound analysis packages already exist, they are more directed to feature extraction for machine learning purposes. Additionally, some features of interest, like time dependent decay, onset shape and Fourier transform peaks distribution are not computable trivially or accurately with existing tools.
