AcMus is a project on musical acoustics devoted to the development of models and computer tools for the study of room acoustics and focus on helping the investigation of issues related to the design, control and acoustic treatment of environments. AcMus has not been maintained for a few years now, but the code may still be useful. We consider the current repository to be at https://gitlab.com/ccsl-usp/acmus .
compariSong is an audio tool to support query by singing/humming. It compares a database of popular songs with a hummed-by-user melody and returns the closest matches.
